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"

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" font="default" size="100%">9</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24934643?dopt=Abstract</style></custom1></record></records></xml>
