(Submitter supplied) Interest focuses on genes encoding histone demethylases in hematologic malignancies, such as EZH2 (enhancer of zeste homolog 2). EZH2 mutations were recurrently observed in lymphomas and chronic myeloid malignancies, but data in acute leukemias are limited. We investigated 13 PICALM-MLLT10 (=CALM-AF10) rearranged acute leukemia predominantly of T-lineage (7 m/6 f; 6–53 years) by deep-sequencing for EZH2mut and identified 3 (23%) EZH2mut carriers: one splice site mutation in exon 14, while two patients had missense mutations in the D1 region of exon 5 which interacts with different DNA methyltransferase genes (but no DNMT3Amut was detected in the 13 PICALM-MLLT10-positive patients). more...

Analysis of mononuclear cells from PICALM-MLLT10-positive T-cell acute lymphoblastic leukemia (T-ALL) patients (2 cases with histone methyltransferase gene EZH2 mutations) and PICALM-MLLT10-negative T-ALL patients. Results provide insight into molecular mechanisms underlying the leukemia subtypes.
