Among them, ACTN1-related thrombocytopenia (ACTN1-RT; Online Mendelian Inheritance in Man: 615193) is one of the most recently identified forms. It has been described as a mild autosomal dominant macrothrombocytopenia caused by mutations in ACTN1, a gene encoding for one of the two non-muscle isoforms of α-actinin. We recently identified seven new unrelated families with ACTN1-RT caused by different mutations. Two of them are novel missense variants (p.Trp128Cys and p.Pro233Leu), whose pathogenic role has been confirmed by in vitro studies. Together with the 10 families we have previously described, our cohort of ACTN1-RT now consists of 49 individuals carrying ACTN1 mutations. This is the largest case series ever collected and enabled a critical evaluation of the clinical aspects of the disease. We concluded that ACTN1-RT is the fourth most frequent form of IT worldwide and it is characterized by platelet macrocytosis in all affected subjects and mild thrombocytopenia in less than 80% of cases. The risk of bleeding, either spontaneous or upon haemostatic challenge, is negligible and there are no other associated defects, either congenital or acquired. Therefore, ACTN1-RT is a benign form of IT, whose diagnosis provides affected individuals and their families with a good prognosis.&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/30351444?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%">Farruggia, Piero</style></author><author><style face="normal" font="default" size="100%">Puccio, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Fioredda, Francesca</style></author><author><style face="normal" font="default" size="100%">Lanza, Tiziana</style></author><author><style face="normal" font="default" size="100%">Porretti, Laura</style></author><author><style face="normal" font="default" size="100%">Ramenghi, Ugo</style></author><author><style face="normal" font="default" size="100%">Barone, Angelica</style></author><author><style face="normal" font="default" size="100%">Bonanomi, Sonia</style></author><author><style face="normal" font="default" size="100%">Finocchi, Andrea</style></author><author><style face="normal" font="default" size="100%">Ghilardi, Roberta</style></author><author><style face="normal" font="default" size="100%">Ladogana, Saverio</style></author><author><style face="normal" font="default" size="100%">Marra, Nicoletta</style></author><author><style face="normal" font="default" size="100%">Martire, Baldassare</style></author><author><style face="normal" font="default" size="100%">Notarangelo, Lucia Dora</style></author><author><style face="normal" font="default" size="100%">Onofrillo, Daniela</style></author><author><style face="normal" font="default" size="100%">Pillon, Marta</style></author><author><style face="normal" font="default" size="100%">Russo, Giovanna</style></author><author><style face="normal" font="default" size="100%">Lo Valvo, Laura</style></author><author><style face="normal" font="default" size="100%">Serafinelli, Jessica</style></author><author><style face="normal" font="default" size="100%">Tucci, Fabio</style></author><author><style face="normal" font="default" size="100%">Zunica, Fiammetta</style></author><author><style face="normal" font="default" size="100%">Verzegnassi, Federico</style></author><author><style face="normal" font="default" size="100%">Dufour, Carlo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Autoimmune neutropenia of childhood secondary to other autoimmune disorders: Data from the Italian neutropenia registry.</style></title><secondary-title><style face="normal" font="default" size="100%">Am J Hematol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Am.

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%">Randi, Maria L</style></author><author><style face="normal" font="default" size="100%">Geranio, Giulia</style></author><author><style face="normal" font="default" size="100%">Bertozzi, Irene</style></author><author><style face="normal" font="default" size="100%">Micalizzi, Concetta</style></author><author><style face="normal" font="default" size="100%">Ramenghi, Ugo</style></author><author><style face="normal" font="default" size="100%">Tucci, Fabio</style></author><author><style face="normal" font="default" size="100%">Notarangelo, Lucia D</style></author><author><style face="normal" font="default" size="100%">Ladogana, Saverio</style></author><author><style face="normal" font="default" size="100%">Menna, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Giordano, Paola</style></author><author><style face="normal" font="default" size="100%">Consarino, Caterina</style></author><author><style face="normal" font="default" size="100%">Farruggia, Piero</style></author><author><style face="normal" font="default" size="100%">Zanazzo, Giulio A</style></author><author><style face="normal" font="default" size="100%">Fiori, Giovanni M</style></author><author><style face="normal" font="default" size="100%">Burnelli, Roberta</style></author><author><style face="normal" font="default" size="100%">Russo, Giovanna</style></author><author><style face="normal" font="default" size="100%">Jankovich, Momcilo</style></author><author><style face="normal" font="default" size="100%">Peroni, Edoardo</style></author><author><style face="normal" font="default" size="100%">Duner, Elena</style></author><author><style face="normal" font="default" size="100%">Basso, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Fabris, Fabrizio</style></author><author><style face="normal" font="default" size="100%">Putti, Maria C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Are all cases of paediatric essential thrombocythaemia really myeloproliferative neoplasms?

Here, we assessed 89 children with a clinical diagnosis of ET and found that 23 patients (25·8%) had a clonal disease. The JAK2 V617F mutation was identified in 14 children, 1 child had the MPL W515L mutation, and 6 had CALR mutations. The monoclonal X-chromosome inactivation pattern was seen in six patients (two with JAK2 V617F and two with CALR mutations). The other 66 patients (74·2%) had persistent thrombocytosis with no clonality. There were no clinical or haematological differences between the clonal and non-clonal patients. The relative proportion of ET-specific mutations in the clonal children was much the same as in adults. The higher prevalence of non-clonal cases suggests that some patients may not have myeloproliferative neoplasms, with significant implications for their

syndrome characterized by congenital thrombocytopenia associated with the risk of developing progressive nephropathy, sensorineural deafness, and presenile cataract. During the collection of a large case-series of patients with MYH9-RD we noticed several cases with unexplained elevation of liver enzymes. Our aim was to evaluate if the alteration of liver tests is a feature of the MYH9-RD and to define its clinical significance.&lt;/p&gt;&lt;p&gt;&lt;b&gt;METHODS AND FINDINGS: &lt;/b&gt;Data concerning liver tests, prospectively recorded in the Italian Registry for MYH9-RD, were collected and compared with those of three control populations: patients with autoimmune thrombocytopenia, patients with inherited thrombocytopenias other than MYH9-RD, and the participants to a large epidemiologic survey in an Italian geographic isolate. Thirty-eight of 75 evaluable MYH9-RD patients (50.7%) showed an elevation of ALT and/or AST, and 17 of 63 (27.0%) an increase of GGT. The increases ranged from 1.9 ± 0.7 to 2.7 ± 1.6 fold the upper normal limit. The prevalence of liver test alterations was significantly higher in MYH9-RD patients than in each of the control populations, with odds ratios ranging from 8.2 (95% CIs 2.2-44.8) to 24.7 (14.8-40.8). Clinical follow-up and more detailed liver studies of a subset of patients, including ultrasound liver scan, liver elastography and liver biopsy in one case, did not show any significant structural damage or evolution towards liver insufficiency.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS: &lt;/b&gt;Elevation of liver enzymes is a frequent and previously unrecognized feature of the MYH9-RD syndrome; however, this defect does not appear to have poor prognostic value.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/22558294?dopt=Abstract</style></custom1></record></records></xml>
