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%">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

&lt;/b&gt;Bernard-Soulier syndrome is a very rare form of inherited 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></records></xml>
