More accurate leukemia diagnosis expected as researchers refine leukemia classification

"Part of precision medicine is an accurate molecular diagnosis, which this study provides to more patients." A novel subtype-defining alteration Alterations of the transcription factor gene PAX5 defined two new subtypes, including PAX5 P80R, as the first lymphoblastic leukemia initiated by a point mutation.

"These findings suggest that the founding mutation occurs early in blood cell development, in some cases in hematopoietic stem cells, and results in an acute leukemia with features of both myeloid and lymphoid cells," said Thomas Alexander, M.D., formerly of St. Jude and now of the University of North Carolina at Chapel Hill.
