NOTCH1 mutation in a female with myeloid/NK cell precursor acute leukemia.
A 6-year-old Japanese female was diagnosed as having myeloid/NK cell precursor acute leukemia (MNKL) using immunocytochemical analysis. The patient was treated by cord blood transplantation from an HLA 1-locus mismatched unrelated donor after chemotherapy comprising cytosine arabinoside, idarubicin, etoposide, and L-asparaginase. We detected a nonsense mutation, C7412A, resulting in S2471X, where X is a terminal codon, in the PEST domain of NOTCH1 in this patient. The presence of the NOTCH1 activating mutation in MNKL might suggest a possible role in the leukemogenesis of MNKL.
