Translocation of CD3D gene in an acute myeloid leukemia (M5) with t(11;17)(q23;21).
Cytogenetic studies in patients with acute leukemia showed structural abnormalities on chromosome 11 at band q23 in five cases. Four of these had acute lymphoblastic leukemia (ALL) associated with t(4;11)(q21;q23) and one case had acute nonlymphoblastic leukemia (ANLL) (M5) associated with t(11;17)(q23;q21). We examined the CD3D and c-ets-1 genes in the t(11;17)(q23;q21) patient to ascertain any association between them and the chromosome change. In situ hybridization results showed that unlike in other studied cases with rearrangements of 11q23, the CD3D gene in the t(11;17)(q23;21) is transposed to the der(17) chromosome, providing evidence for a different breakpoint in the 11q23 region.
