- Deletion of RUNX1 exons 1 and 2 associated with familial platelet disorder with propensity to acute myeloid leukemia(2018) SILVA, Marcela Cavalcante de Andrade; KREPISCHI, Ana Cristina Victorino; KULIKOWSKI, Leslie Domenici; ZANARDO, Evelin Aline; NARDINELLI, Luciana; LEAL, Aline Medeiros; COSTA, Silvia Souza; MUTO, Nair Hideki; ROCHA, Vanderson; VELLOSO, Elvira Deolinda Rodrigues PereiraFamilial platelet disorder with propensity to acute myeloid leukemia (FPD/AML) associated with RUNX1 mutations is an autosomal dominant disorder included in the group of the myeloid neoplasms with germ line predisposition. We describe two brothers who were diagnosed with hematological malignancies (one with AML and the other with T-cell lymphoblastic lymphoma). There was a history of leukemia in the paternal family and two of their siblings presented with low platelet counts and no history of significant bleeding. A microdeletion encompassing exons 1-2 of RUNX1 (outside the cluster region of the Runt Homology domain and the transactivation domain) was detected in six family members using array-CGH and MLPA validation. A low platelet count was not present in all deletion carriers and, therefore, it should not be used as an indication for screening in suspected families and family members.
