Family platelet disorder with propensity to acute myeloid leukemia: new family with RUNX1 mutation

https://doi.org/10.17650/1818-8346-2011-6-4-6-11

Abstract

Familial platelet disorder with propensity to develop acute myeloid leukemia (FPD/AML) is a rare autosomal dominant disorder caused by inherited mutation of RUNX1. To date only 35 families have been described. We report on a family in which number and function of platelet were impaired in members of 4 generations. Acute myeloid leukemia developed in 3 members of 2 generations. The age of leukemia development was 11, 19 и 76 years. In all 5 affected family members available for study novel heterozygous mutation in runt domain of RUNX1 (c2018 A > C, pT147P) was detected by direct sequencing. This mutation is predicted to impair binding of CBF to core motif of DNA. Two affected patients died of leukemia; while in one complete remission was achieved with conventional and consolidated with allogeneic BMT from HLA-matched sister proved to be RUNX1 mutation negative.
