Description
12/150 patients with de novo myelodysplastic syndrome screened for DNMT3A mutations (bone marrow and paired normal skin) had heterozygous mutations with predicted translational consequences. 1 patient was identified with 2 nonsynonymous coding mutations. R882 mutations accounted for 4/13 reported mutations, P904L for 2/13 mutations and the remaining had not been previously reported at the time of this report. Overall and event-free survival were worse for DNMT3A mutant patients although transplantation status was not considered (log-rank p=0.005 and p=0.009). Transformation to AML was increased for mutant 7/12 (58%) versus wildtype 39/138 (28%) patients (p=0.007). The authors note larger cohorts will be required to confirm these results.
