Effect of DNMT3A variant allele frequency and double mutation on clinicopathologic features of patients with de novo AML.

Abstract excerpt

The clinicopathologic features of DNA methyltransferase 3A (DNMT3A)-mutated de novo acute myeloid leukemia (AML), and the significance of variant type, variant allele frequency (VAF), and multiple concomitant DNMT3A mutations, remain poorly defined. We examined 104 DNMT3A-mutated de novo AML patients from 2 major centers. Most (82%) had normal karyotype (NK); R882H variants were frequent(38%). The most commonly...
