Despite progress being made in defining the genetic causes of ITs, nearly 50% of patients with familial thrombocytopenia are affected with forms of unknown origin. Here, through exome sequencing of 2 siblings with autosomal-recessive thrombocytopenia, we identified biallelic loss-of-function variants in  This gene encodes for a receptor-like PTP, PTPRJ (or CD148), which is expressed abundantly in platelets and megakaryocytes. Consistent with the predicted effects of the variants, both probands have an almost complete loss of PTPRJ at the messenger RNA and protein levels. To investigate the pathogenic role of PTPRJ deficiency in hematopoiesis in vivo, we carried out CRISPR/Cas9-mediated ablation of  (the ortholog of human ) in zebrafish, which induced a significantly decreased number of CD41 thrombocytes in vivo. Moreover, megakaryocytes of our patients showed impaired maturation and profound defects in SDF1-driven migration and formation of proplatelets in vitro. Silencing of  in a human megakaryocytic cell line reproduced the functional defects observed in patients' megakaryocytes. The disorder caused by  mutations presented as a nonsyndromic thrombocytopenia characterized by spontaneous bleeding, small-sized platelets, and impaired platelet responses to the GPVI agonists collagen and convulxin. These platelet functional defects could be attributed to reduced activation of Src family kinases. Taken together, our data identify a new form of IT and highlight a hitherto unknown fundamental role for PTPRJ in platelet biogenesis.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/30591527?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Melazzini, Federica</style></author><author><style face="normal" font="default" size="100%">Palombo, Flavia</style></author><author><style face="normal" font="default" size="100%">Balduini, Alessandra</style></author><author><style face="normal" font="default" size="100%">De Rocco, Daniela</style></author><author><style face="normal" font="default" size="100%">Marconi, Caterina</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Gnan, Chiara</style></author><author><style face="normal" font="default" size="100%">Pippucci, Tommaso</style></author><author><style face="normal" font="default" size="100%">Bozzi, Valeria</style></author><author><style face="normal" font="default" size="100%">Faleschini, Michela</style></author><author><style face="normal" font="default" size="100%">Barozzi, Serena</style></author><author><style face="normal" font="default" size="100%">Doubek, Michael</style></author><author><style face="normal" font="default" size="100%">Di Buduo, Christian A</style></author><author><style face="normal" font="default" size="100%">Stano Kozubik, Katerina</style></author><author><style face="normal" font="default" size="100%">Radova, Lenka</style></author><author><style face="normal" font="default" size="100%">Loffredo, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Pospisilova, Sarka</style></author><author><style face="normal" font="default" size="100%">Alfano, Caterina</style></author><author><style face="normal" font="default" size="100%">Seri, Marco</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Clinical and pathogenetic features of ETV6 related thrombocytopenia with predisposition to acute lymphoblastic leukemia.</style></title><secondary-title><style face="normal" font="default" size="100%">Haematologica</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Haematologica</style></alt-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2016 Jun 30</style></date></pub-dates></dates><language><style face="normal" font="default" size="100%">ENG</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;ETV6-related thrombocytopenia (ETV6-RT) is an autosomal dominant thrombocytopenia that has been recently identified in a few families and has been suspected to predispose to hematological malignancies. To gain further information on this disorder, we searched for ETV6 mutations in the 130 families with inherited thrombocytopenia of unknown origin from our cohort of 274 consecutive pedigrees with familial thrombocytopenia. We identified 20 ETV6-RT patients from 7 pedigrees. They have 5 different ETV6 variants, including three novel mutations affecting the highly conserved E26 transformation-specific domain. The relative frequency of ETV6-RT resulted 2.6% in the whole case series and 4.6% among the families with known forms of inherited thrombocytopenia. The degree of thrombocytopenia and bleeding tendency of ETV6-RT patients were mild, but 4 subjects developed B-cell acute lymphoblastic leukemia during childhood, resulting in a significantly increased incidence compared to the general population. Clinical and laboratory findings did not identify any peculiar defects that can be used to suspect this disorder by routine diagnostic workup. However, at variance with most inherited thrombocytopenias, platelet size was not enlarged. In vitro studies revealed that patients megakaryocytes have defective maturation and impaired proplatelet formation. Moreover, ETV6-RT platelets have reduced ability to spread on fibrinogen. Since also the dominant thrombocytopenias due to mutations in RUNX1 and ANKRD26 are characterized by normal platelet size and predispose to hematological malignancies, we suggest that mutation screening of ETV6, RUNX1 and ANKRD26 should be performed in all the subjects with autosomal dominant thrombocytopenia and normal platelet size.&lt;/p&gt;</style></abstract><custom1><style

thrombocytopenias (ITs) are a heterogeneous group of syndromic and nonsyndromic diseases caused by mutations affecting different genes. Alterations of ACTN1, the gene encoding for α-actinin 1, have recently been identified in a few families as being responsible for a mild form of IT (ACTN1-related thrombocytopenia; ACTN1-RT). To better characterize this disease, we screened ACTN1 in 128 probands and found 10 (8 novel) missense heterozygous variants in 11 families. Combining bioinformatics, segregation, and functional studies, we demonstrated that all but 1 amino acid substitution had deleterious effects. The clinical and laboratory findings of 31 affected individuals confirmed that ACTN1-RT is a mild macrothrombocytopenia with low risk for bleeding. Low reticulated platelet counts and only slightly increased serum thrombopoietin levels indicated that the latest phases of megakaryopoiesis were affected. Given its relatively high frequency in our cohort (4.2%), ACTN1-RT has to be taken into consideration in the differential diagnosis of ITs.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25361813?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Noetzli, Leila</style></author><author><style face="normal" font="default" size="100%">Lo, Richard W</style></author><author><style face="normal" font="default" size="100%">Lee-Sherick, Alisa B</style></author><author><style face="normal" font="default" size="100%">Callaghan, Michael</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author><author><style face="normal" font="default" size="100%">Rajpurkar, Madhvi</style></author><author><style face="normal" font="default" size="100%">Jones, Kenneth</style></author><author><style face="normal" font="default" size="100%">Gowan, Katherine</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Gnan, Chiara</style></author><author><style face="normal" font="default" size="100%">De Rocco, Daniela</style></author><author><style face="normal" font="default" size="100%">Doubek, Michael</style></author><author><style face="normal" font="default" size="100%">Li, Ling</style></author><author><style face="normal" font="default" size="100%">Lu, Lily</style></author><author><style face="normal" font="default" size="100%">Leung, Richard</style></author><author><style face="normal" font="default" size="100%">Landolt-Marticorena, Carolina</style></author><author><style face="normal" font="default" size="100%">Hunger, Stephen</style></author><author><style face="normal" font="default" size="100%">Heller, Paula</style></author><author><style face="normal" font="default" size="100%">Gutierrez-Hartmann, Arthur</style></author><author><style face="normal" font="default" size="100%">Xiayuan, Liang</style></author><author><style face="normal" font="default" size="100%">Pluthero, Fred G</style></author><author><style face="normal" font="default" size="100%">Rowley, Jesse W</style></author><author><style face="normal" font="default" size="100%">Weyrich, Andrew S</style></author><author><style face="normal" font="default" size="100%">Kahr, Walter H A</style></author><author><style face="normal" font="default" size="100%">Porter, Christopher C</style></author><author><style face="normal" font="default" size="100%">Di Paola, Jorge</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Germline mutations in ETV6 are associated with thrombocytopenia, red cell macrocytosis and predisposition to lymphoblastic leukemia.</style></title><secondary-title><style face="normal" font="default" size="100%">Nat Genet</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Nat.

We identified a family with autosomal dominant thrombocytopenia, high erythrocyte mean corpuscular volume (MCV) and two occurrences of B cell-precursor acute lymphoblastic leukemia (ALL). Whole-exome sequencing identified a heterozygous single-nucleotide change in ETV6 (ets variant 6), c.641C&gt;T, encoding a p.Pro214Leu substitution in the central domain, segregating with thrombocytopenia and elevated MCV. A screen of 23 families with similar phenotypes identified 2 with ETV6 mutations. One family also had a mutation encoding p.Pro214Leu and one individual with ALL. The other family had a c.1252A&gt;G transition producing a p.Arg418Gly substitution in the DNA-binding domain, with alternative splicing and exon skipping. Functional characterization of these mutations showed aberrant cellular localization of mutant and endogenous ETV6, decreased transcriptional repression and altered megakaryocyte maturation. Our findings underscore a key role for ETV6 in platelet formation and leukemia predisposition.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default"

mothers and the newborns are potentially at risk of bleeding. However, medical management of this condition cannot be based on evidence because of the lack of consistent information in the literature. To advance knowledge on this matter, we performed a multicentric, retrospective study evaluating 339 pregnancies in 181 women with 13 different forms of inherited thrombocytopenia. Neither the degree of thrombocytopenia nor the severity of bleeding tendency worsened during pregnancy and the course of pregnancy did not differ from that of healthy subjects in terms of miscarriages, fetal bleeding and pre-term births. The degree of thrombocytopenia in the babies was similar to that in the mother. Only 7 of 156 affected newborns had delivery-related bleeding, but 2 of them died of cerebral hemorrhage. The frequency of delivery-related maternal bleeding ranged from 6.8% to 14.2% depending on the definition of abnormal blood loss, suggesting that the risk of abnormal blood loss was increased with respect to the general population. However, no mother died or had to undergo hysterectomy to arrest bleeding. The search for parameters predicting delivery-related bleeding in the mother suggested that hemorrhages requiring blood transfusion were more frequent in women with history of severe bleedings before pregnancy and with platelet count at delivery below 50 × 10(9)/L.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24763399?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Klersy, Catherine</style></author><author><style face="normal" font="default" size="100%">Gresele, Paolo</style></author><author><style face="normal" font="default" size="100%">Lee, Kieran J D</style></author><author><style face="normal" font="default" size="100%">De Rocco, Daniela</style></author><author><style face="normal" font="default" size="100%">Bozzi, Valeria</style></author><author><style face="normal" font="default" size="100%">Russo, Giovanna</style></author><author><style face="normal" font="default" size="100%">Heller, Paula G</style></author><author><style face="normal" font="default" size="100%">Loffredo, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Ballmaier, Matthias</style></author><author><style face="normal" font="default" size="100%">Fabris, Fabrizio</style></author><author><style face="normal" font="default" size="100%">Beggiato, Eloise</style></author><author><style face="normal" font="default" size="100%">Kahr, Walter H A</style></author><author><style face="normal" font="default" size="100%">Pujol-Moix, Núria</style></author><author><style face="normal" font="default" size="100%">Platokouki, Helen</style></author><author><style face="normal" font="default" size="100%">Van Geet, Christel</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Yerram, Preethi</style></author><author><style face="normal" font="default" size="100%">Hermans, Cedric</style></author><author><style face="normal" font="default" size="100%">Gerber, Bernhard</style></author><author><style face="normal" font="default" size="100%">Economou, Marina</style></author><author><style face="normal" font="default" size="100%">De Groot, Marco</style></author><author><style face="normal" font="default" size="100%">Zieger, Barbara</style></author><author><style face="normal" font="default" size="100%">De Candia, Erica</style></author><author><style face="normal" font="default" size="100%">Fraticelli, Vincenzo</style></author><author><style face="normal" font="default" size="100%">Kersseboom, Rogier</style></author><author><style face="normal" font="default" size="100%">Piccoli, Giorgina B</style></author><author><style face="normal" font="default" size="100%">Zimmermann, Stefanie</style></author><author><style face="normal" font="default" size="100%">Fierro, Tiziana</style></author><author><style face="normal" font="default" size="100%">Glembotsky, Ana C</style></author><author><style face="normal" font="default" size="100%">Vianello, Fabrizio</style></author><author><style face="normal" font="default" size="100%">Zaninetti, Carlo</style></author><author><style face="normal" font="default" size="100%">Nicchia, Elena</style></author><author><style face="normal" font="default" size="100%">Güthner, Christiane</style></author><author><style face="normal" font="default" size="100%">Baronci, Carlo</style></author><author><style face="normal" font="default" size="100%">Seri, Marco</style></author><author><style face="normal" font="default" size="100%">Knight, Peter J</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">MYH9-related disease: a novel prognostic model to predict the clinical evolution of the disease based on genotype-phenotype correlations.</style></title><secondary-title><style face="normal" font="default" size="100%">Hum Mutat</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Hum.

MYH9-RD is characterized by a considerable variability in clinical evolution: patients present at birth with only thrombocytopenia, but some of them subsequently develop sensorineural deafness, cataract, and/or nephropathy often leading to end-stage renal disease (ESRD). We searched for genotype-phenotype correlations in the largest series of consecutive MYH9-RD patients collected so far (255 cases from 121 families). Association of genotypes with noncongenital features was assessed by a generalized linear regression model. The analysis defined disease evolution associated to seven different MYH9 genotypes that are responsible for 85% of MYH9-RD cases. Mutations hitting residue R702 demonstrated a complete penetrance for early-onset ESRD and deafness. The p.D1424H substitution associated with high risk of developing all the noncongenital manifestations of disease. Mutations hitting a distinct hydrophobic seam in the NMMHC-IIA head domain or substitutions at R1165 associated with high risk of deafness but low risk of nephropathy or cataract. Patients with p.E1841K, p.D1424N, and C-terminal deletions had low risk of noncongenital defects. These findings are essential to patients' clinical management and genetic counseling and are discussed in view of molecular pathogenesis of MYH9-RD.&lt;/p&gt;</style></abstract><issue><style

thrombocytopenias (ITs), and evaluation of blood films is recommended as an essential step for differential diagnosis of these disorders. Nevertheless, what we presently know about this subject is derived mainly from anecdotal evidence. To improve knowledge in this field, we evaluated platelet size on blood films obtained from 376 patients with all 19 forms of IT identified so far and found that these conditions differ not only in mean platelet diameter, but also in platelet diameter distribution width and the percentage of platelets with increased or reduced diameters. On the basis of these findings, we propose a new classification of ITs according to platelet size. It distinguishes forms with giant platelets, with large platelets, with normal or slightly increased platelet size, and with normal or slightly decreased platelet size. We also measured platelet diameters in 87 patients with immune thrombocytopenia and identified cutoff values for mean platelet diameter and the percentage of platelets with increased or reduced size that have good diagnostic accuracy in differentiating ITs with giant platelets and with normal or slightly decreased platelet size from immune thrombocytopenia and all other forms of IT.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24990887?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author><author><style face="normal" font="default" size="100%">Kunishima, Shinji</style></author><author><style face="normal" font="default" size="100%">De Rocco, Daniela</style></author><author><style face="normal" font="default" size="100%">Zieger, Barbara</style></author><author><style face="normal" font="default" size="100%">Rand, Margaret L</style></author><author><style face="normal" font="default" size="100%">Pujol-Moix, Núria</style></author><author><style face="normal" font="default" size="100%">Caliskan, Umran</style></author><author><style face="normal" font="default" size="100%">Tokgoz, Huseyin</style></author><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Srivastava, Alok</style></author><author><style face="normal" font="default" size="100%">Ward, Christopher</style></author><author><style face="normal" font="default" size="100%">Morel-Kopp, Marie-Christine</style></author><author><style face="normal" font="default" size="100%">Alessi, Marie-Christine</style></author><author><style face="normal" font="default" size="100%">Bellucci, Sylvia</style></author><author><style face="normal" font="default" size="100%">Beurrier, Philippe</style></author><author><style face="normal" font="default" size="100%">de Maistre, Emmanuel</style></author><author><style face="normal" font="default" size="100%">Favier, Rémi</style></author><author><style face="normal" font="default" size="100%">Hézard, Nathalie</style></author><author><style face="normal" font="default" size="100%">Hurtaud-Roux, Marie-Françoise</style></author><author><style face="normal" font="default" size="100%">Latger-Cannard, Véronique</style></author><author><style face="normal" font="default" size="100%">Lavenu-Bombled, Cécile</style></author><author><style face="normal" font="default" size="100%">Proulle, Valérie</style></author><author><style face="normal" font="default" size="100%">Meunier, Sandrine</style></author><author><style face="normal" font="default" size="100%">Négrier, Claude</style></author><author><style face="normal" font="default" size="100%">Nurden, Alan</style></author><author><style face="normal" font="default" size="100%">Randrianaivo, Hanitra</style></author><author><style face="normal" font="default" size="100%">Fabris, Fabrizio</style></author><author><style face="normal" font="default" size="100%">Platokouki, Helen</style></author><author><style face="normal" font="default" size="100%">Rosenberg, Nurit</style></author><author><style face="normal" font="default" size="100%">HadjKacem, Basma</style></author><author><style face="normal" font="default" size="100%">Heller, Paula G</style></author><author><style face="normal" font="default" size="100%">Karimi, Mehran</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author><author><style face="normal" font="default" size="100%">Pastore, Annalisa</style></author><author><style face="normal" font="default" size="100%">Lanza, Francois</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Spectrum of the mutations in Bernard-Soulier syndrome.</style></title><secondary-title><style face="normal" font="default" size="100%">Hum Mutat</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Hum.

Most of the mutations identified in the genes encoding for the GP1BA (GPIbα), GP1BB (GPIbβ), and GP9 (GPIX) subunits prevent expression of the complex at the platelet membrane or more rarely its interaction with VWF. As a consequence, platelets are unable to adhere to the vascular subendothelium and agglutinate in response to ristocetin. In order to collect information on BSS patients, we established an International Consortium for the study of BSS, allowing us to enrol and genotype 132 families (56 previously unreported). With 79 additional families for which molecular data were gleaned from the literature, the 211 families characterized so far have mutations in the GP1BA (28%), GP1BB (28%), or GP9 (44%) genes. There is a wide spectrum of mutations with 112 different variants, including 22 novel alterations. Consistent with the rarity of the disease, 85% of the probands carry homozygous mutations with evidence of founder effects in some geographical areas. This overview provides the first global picture of the molecular basis of BSS and will lead to improve patient diagnosis and management.&lt;/p&gt;</style></abstract><issue><style face="normal"

in MYH9, the gene encoding for the heavy chain of non-muscle myosin IIA (myosin-9). MYH9-RD is characterized by congenital macrothrombocytopenia and typical inclusion bodies in neutrophils associated with a variable risk of developing sensorineural deafness, presenile cataract, and/or progressive nephropathy. The spectrum of mutations responsible for MYH9-RD is limited. We report five families, each with a novel MYH9 mutation. Two mutations, p.Val34Gly and p.Arg702Ser, affect the motor domain of myosin-9, whereas the other three, p.Met847_Glu853dup, p.Lys1048_Glu1054del, and p.Asp1447Tyr, hit the coiled-coil tail domain of the protein. The motor domain mutations were associated with more severe clinical phenotypes than those in the tail domain.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default"

thrombocytopenia that derives from mutations in GPIbα, GPIbβ, or GPIX and is typically inherited as a recessive disease. However, some years ago it was shown that the monoallelic c.515C&gt;T transition in the GPIBA gene (Bolzano mutation) was responsible for macrothrombocytopenia in a few Italian patients.&lt;/p&gt;&lt;p&gt;&lt;b&gt;DESIGN AND METHODS: &lt;/b&gt;Over the past 10 years, we have searched for the Bolzano mutation in all subjects referred to our institutions because of an autosomal, dominant form of thrombocytopenia of unknown origin.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;We identified 42 new Italian families (103 cases) with a thrombocytopenia induced by monoallelic Bolzano mutation. Analyses of the geographic origin of affected pedigrees and haplotypes indicated that this mutation originated in southern Italy. Although the clinical expression was variable, patients with this mutation typically had a mild form of Bernard-Soulier syndrome with mild thrombocytopenia and bleeding tendency. The most indicative laboratory findings were enlarged platelets and reduced GPIb/IX/V platelet expression; in vitro platelet aggregation was normal in nearly all of the cases.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;Our study indicates that monoallelic Bolzano mutation is the most frequent cause of inherited thrombocytopenia in Italy, affecting 20% of patients recruited at our institutions during the last 10 years. Because many people from southern Italy have emigrated during the last century, this mutation may have spread to other countries.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21933849?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Biino, Ginevra</style></author><author><style face="normal" font="default" size="100%">Gasparini, Paolo</style></author><author><style face="normal" font="default" size="100%">d'Adamo, Pio</style></author><author><style face="normal" font="default" size="100%">Ciullo, Marina</style></author><author><style face="normal" font="default" size="100%">Nutile, Teresa</style></author><author><style face="normal" font="default" size="100%">Toniolo, Daniela</style></author><author><style face="normal" font="default" size="100%">Sala, Cinzia</style></author><author><style face="normal" font="default" size="100%">Minelli, Cosetta</style></author><author><style face="normal" font="default" size="100%">Gögele, Martin</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of age, sex and ethnicity on platelet count in five Italian geographic isolates: mild thrombocytopenia may be physiological.</style></title><secondary-title><style face="normal" font="default" size="100%">Br J Haematol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Br.

Due to the rarity of the disease, there are reports only on a few cases compromising any attempt to establish correlations between genotype and phenotype. In order to identify any associations, we describe the largest case series ever reported, which was evaluated systematically at the same center.&lt;/p&gt;&lt;p&gt;&lt;b&gt;DESIGN AND METHODS: &lt;/b&gt;Thirteen patients with the disease and seven obligate carriers were enrolled. We collected clinical aspects and determined platelet features, including number and size, expression of membrane glycoproteins, and ristocetin induced platelet aggregation. Mutations were identified by direct sequencing of the GP1BA, GP1BB, and GP9 genes and their effect was shown by molecular modeling analyses.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;Patients all had a moderate thrombocytopenia with giant platelets and a bleeding tendency whose severity varied among individuals. Consistent with expression levels of GPIbα always lower than 10% of control values, platelet aggregation was absent or severely reduced. Homozygous mutations were identified in the GP1BA, GP1BB and GP9 genes; six were novel alterations expected to destabilize the conformation of the respective protein. Except for obligate carriers of a GP9 mutation with a reduced GPIb/IX/V expression and defective aggregation, all the other carriers had no obvious anomalies.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;Regardless of mutations identified, the patients' bleeding diathesis did not correlate with thrombocytopenia, which was always moderate, and platelet GPIbα expression, which was always severely impaired. Obligate carriers had features similar to controls though their GPIb/IX/V expression showed discrepancies. Aware of the limitations of our cohort, we cannot define any correlations. However, further investigations should be encouraged to better understand the causes of this rare and underestimated disease.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default"

thrombocytopenia 2 (THC2) was considered an exceedingly rare form of autosomal dominant thrombocytopenia and only 2 families were known. However, we recently identified mutations in the 5'-untranslated region of the ANKRD26 gene in 9 THC2 families. Here we report on 12 additional pedigrees with ANKRD26 mutations, 6 of which are new. Because THC2 affected 21 of the 210 families in our database, it has to be considered one of the less rare forms of inherited thrombocytopenia. Analysis of all 21 families with ANKRD26 mutations identified to date revealed that thrombocytopenia and bleeding tendency were usually mild. Nearly all patients had no platelet macrocytosis, and this characteristic distinguishes THC2 from most other forms of inherited thrombocytopenia. In the majority of cases, platelets were deficient in glycoprotein Ia and α-granules, whereas in vitro platelet aggregation was normal. Bone marrow examination and serum thrombopoietin levels suggested that thrombocytopenia was derived from dysmegakaryopoiesis. Unexplained high values of hemoglobin and leukocytes were observed in a few cases. An unexpected finding that warrants further investigation was a high incidence of acute leukemia. Given the scarcity of distinctive characteristics, the ANKRD26-related thrombocytopenia has to be taken into consideration in the differential diagnosis of isolated thrombocytopenias.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">24</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21467542?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pippucci, Tommaso</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author><author><style face="normal" font="default" size="100%">Perrotta, Silverio</style></author><author><style face="normal" font="default" size="100%">Pujol-Moix, Núria</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Castegnaro, Giovanni</style></author><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Gnan, Chiara</style></author><author><style face="normal" font="default" size="100%">Punzo, Francesca</style></author><author><style face="normal" font="default" size="100%">Marconi, Caterina</style></author><author><style face="normal" font="default" size="100%">Gherardi, Samuele</style></author><author><style face="normal" font="default" size="100%">Loffredo, Giuseppe</style></author><author><style face="normal" font="default" size="100%">De Rocco, Daniela</style></author><author><style face="normal" font="default" size="100%">Scianguetta, Saverio</style></author><author><style face="normal" font="default" size="100%">Barozzi, Serena</style></author><author><style face="normal" font="default" size="100%">Magini, Pamela</style></author><author><style face="normal" font="default" size="100%">Bozzi, Valeria</style></author><author><style face="normal" font="default" size="100%">Dezzani, Luca</style></author><author><style face="normal" font="default" size="100%">Di Stazio, Mariateresa</style></author><author><style face="normal" font="default" size="100%">Ferraro, Marcella</style></author><author><style face="normal" font="default" size="100%">Perini, Giovanni</style></author><author><style face="normal" font="default" size="100%">Seri, Marco</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Mutations in the 5' UTR of ANKRD26, the ankirin repeat domain 26 gene, cause an autosomal-dominant form of inherited thrombocytopenia, THC2.</style></title><secondary-title><style face="normal" font="default" size="100%">Am J Hum Genet</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Am.

Here, we show that ANKRD26, another gene within the THC2 locus, and neither MASTL nor ACBD5, is mutated in eight unrelated families. ANKRD26 was also found to be mutated in the family previously reported to have an ACBD5 mutation. We identified six different ANKRD26 mutations, which were clustered in a highly conserved 19 bp sequence located in the 5' untranslated region. Mutations were not detected in 500 controls and are absent from the 1000 Genomes database. Available data from an animal model and Dr. Watson's genome give evidence against haploinsufficiency as the pathogenetic mechanism for ANKRD26-mediated thrombocytopenia. The luciferase reporter assay suggests that these 5' UTR mutations might enhance ANKRD26 expression. ANKRD26 is the ancestor of a family of primate-specific genes termed POTE, which have been recently identified as a family of proapoptotic proteins. Dysregulation of apoptosis might therefore be the pathogenetic mechanism, as demonstrated for another thrombocytopenia, THC4. Further investigation is needed to provide evidence supporting this hypothesis.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21211618?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Recent advances in the understanding and management of MYH9-related inherited thrombocytopenias.</style></title><secondary-title><style face="normal" font="default" size="100%">Br J Haematol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Br.

It is transmitted in an autosomal dominant fashion and derives from mutations of MYH9, the gene for the heavy chain of non-muscle myosin IIA. Patients present with congenital macrothrombocytopenia with mild bleeding tendency and may develop kidney dysfunction, deafness and cataracts later in life. The term MYH9-RD encompasses four autosomal-dominant thrombocytopenias that were previously described as distinct disorders, namely May-Hegglin Anomaly, Sebastian, Fechtner and Epstein syndromes. Thrombocytopenia is usually mild and derives from complex defects of megakaryocyte maturation and platelet formation. It is easily diagnosed, in that the presence of giant platelets in peripheral blood raises the suspicion of MYH9-RD and a simple immunofluorescence test on blood films confirms the diagnostic hypothesis. However, genotype/phenotype correlations have been recognized and mutation screening is therefore required to define the risk of acquiring extra-haematological defects. Results of a small clinical study suggested that a non-peptide thrombopoietin mimetic might greatly benefit both thrombocytopenia and bleeding tendency of MYH9-RD patients.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21542825?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pecci, Alessandro</style></author><author><style face="normal" font="default" size="100%">Gresele, Paolo</style></author><author><style face="normal" font="default" size="100%">Klersy, Catherine</style></author><author><style face="normal" font="default" size="100%">Savoia, Anna</style></author><author><style face="normal" font="default" size="100%">Noris, Patrizia</style></author><author><style face="normal" font="default" size="100%">Fierro, Tiziana</style></author><author><style face="normal" font="default" size="100%">Bozzi, Valeria</style></author><author><style face="normal" font="default" size="100%">Mezzasoma, Anna Maria</style></author><author><style face="normal" font="default" size="100%">Melazzini, Federica</style></author><author><style face="normal" font="default" size="100%">Balduini, Carlo L</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Eltrombopag for the treatment of the inherited thrombocytopenia deriving from MYH9 mutations.</style></title><secondary-title><style face="normal" font="default" size="100%">Blood</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Blood</style></alt-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Administration, Oral</style></keyword><keyword><style  face="normal" font="default" size="100%">Adolescent</style></keyword><keyword><style  face="normal" font="default" size="100%">Adult</style></keyword><keyword><style  face="normal" font="default" size="100%">Benzoates</style></keyword><keyword><style  face="normal" font="default" size="100%">Dose-Response Relationship, Drug</style></keyword><keyword><style  face="normal" font="default" size="100%">Female</style></keyword><keyword><style  face="normal" font="default" size="100%">Genetic Predisposition to Disease</style></keyword><keyword><style  face="normal" font="default" size="100%">Humans</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrazines</style></keyword><keyword><style  face="normal" font="default" size="100%">Male</style></keyword><keyword><style  face="normal" font="default" size="100%">Molecular Motor Proteins</style></keyword><keyword><style  face="normal" font="default" size="100%">Mutation</style></keyword><keyword><style  face="normal" font="default" size="100%">Myosin Heavy Chains</style></keyword><keyword><style  face="normal" font="default" size="100%">Platelet Aggregation</style></keyword><keyword><style  face="normal" font="default" size="100%">Platelet Count</style></keyword><keyword><style  face="normal" font="default" size="100%">Pyrazoles</style></keyword><keyword><style  face="normal" font="default" size="100%">Receptors, Thrombopoietin</style></keyword><keyword><style  face="normal" font="default" size="100%">Survival Rate</style></keyword><keyword><style  face="normal" font="default" size="100%">Thrombocytopenia</style></keyword><keyword><style  face="normal" font="default" size="100%">Treatment Outcome</style></keyword><keyword><style  face="normal" font="default" size="100%">Young Adult</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010 Dec 23</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">116</style></volume><pages><style face="normal" font="default" size="100%">5832-7</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Platelet transfusion is currently the primary medical treatment for reducing thrombocytopenia in patients with inherited thrombocytopenias. To evaluate whether stimulating megakaryopoiesis could increase platelet count in these conditions, we treated patients with a severe thrombocytopenia induced by MYH9 mutations (MYH9-related disease) with a nonpeptide thrombopoietin receptor agonist, eltrombopag. Twelve adult patients with MYH9-RD and platelet counts of less than 50 × 10(9)/L received 50 mg of eltrombopag orally per day for 3 weeks. Patients who achieved a platelet count higher than 150 × 10(9)/L stopped therapy, those with 100 to 150 platelets × 10(9)/L continued treatment at the same eltrombopag dose for 3 additional weeks, while those with less than 100 platelets × 10(9)/L increased the eltrombopag dose to 75 mg for 3 weeks. Major responses (platelet count of at least 100 × 10(9)/L or 3 times the baseline value) were obtained in 8 patients, minor responses (platelet counts at least twice the baseline value) in 3. One patient did not respond. Bleeding tendency disappeared in 8 of 10 patients with bleeding symptoms at baseline. Mild adverse events were reported in 2 patients. The availability of thrombopoietin mimetics opened new prospects in the treatment of inherited thrombocytopenias.

Patients present with congenital macrothrombocytopenia and inclusion bodies in neutrophils and might develop sensorineural deafness, presenile cataract, and/or progressive nephropathy leading to end-stage renal failure. In two families with macrothrombocytopenia we identified a novel c.3485G &gt; C mutation in the last nucleotide of exon 25. Bioinformatic tools for splice site prediction and minigene functional test predicted splicing anomalies of exon 25. However, analysis of RNA purified from patient's peripheral blood did not allowed us to detect any anomalies, suggesting that RNA processing is correct at least in this tissue. Therefore, we concluded that c.3485G &gt; C leads to a novel missense mutation (p.Arg1162Thr) of myosin-9, which resulted to be slightly degraded in patient platelets. A precise definition of the effect of mutations is fundamental to improve our knowledge into the pathogenetic mechanisms responsible for the disease.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/20603234?dopt=Abstract</style></custom1></record></records></xml>
