Hematologic Neoplasm with Germline RUNX1 Mutation - CISMeF
Hematologic Neoplasm with Germline RUNX1 MutationNCIt concept
Preferred Label : Hematologic Neoplasm with Germline RUNX1 Mutation;
NCIt definition : An autosomal dominant syndrome characterized by abnormalities in platelet number and
function and enhanced risk of developing myelodysplastic syndrome/acute myeloid leukemia
at a young age. Patients have germline monoallelic mutations in RUNX1 gene. The clinical
presentation is variable, even within the same family. Most affected individuals have
a mild to moderate bleeding tendency. Platelet counts are normal or mildly reduced,
with normal platelet morphology and variable degrees of platelet dysfunction. Distinct
families with germline RUNX1 mutations exhibit varying risks of development of myeloid
neoplasms with 11-100% (median: 44%) of family members affected. (WHO 2017);
