In a study of familial platelet disease with propensity to myeloid malignancies (FPD/AML), an autosomal dominant syndrome characterized by platelet abnormalities and susceptibility to MDS/AML that is caused by the genetic mutation of RUNX1, the authors identified germline RUNX1 mutations in five families with a history of MDS/AML (269). This evidence concerns the gene RUNX1 and myeloid neoplasm.
