Acute lymphoblastic leukemia associated with RCSD1–ABL1 novel fusion gene has a distinct gene expression profile from BCR–ABL1 fusion

摘要

De Braekeleer et al.1 published the first case of acute lymphoblastic leukemia (ALL) associated with a t(1;9)(q24;q34) and showed colocalization of bacterial artificial chromosome (BAC) clones containing the RCSD1 and ABL1 genes, suggesting the presence of a yet undescribed fusion gene. Mustjoki et al.2 identified a second patient.
