Abstract

Abstract : We report a female newborn with acute myelogenous leukemia (AML) associated with a MYB-GATA1 fusion gene. Morphologic findings of myeloid lineage were obtained using light microscopy. Cytogenetic analysis of peripheral blood showed a complex karyotype: 46, X, -X, add(3)(q21), der(6)add(6)(q21)del(6)(q?), +mar1[5]/46, XX[15]. Targeted RNA sequencing revealed a MYB-GATA1 fusion gene. Reduced-dose AML-type chemotherapy resulted in remission and survival for >3 years without relapse. The present case demonstrated the feasibility of carrying out targeted RNA sequencing for identifying MYB-GATA1 and supports the notion that neonatal AML with MYB-GATA1 with reduced chemotherapy may show better prognosis than other highly toxic therapies.
