Abstract:
We report a new chromosomal reciprocal translocation t(5;10)(q33;q22) in a 49-year-old man with atypical chronic myeloid leukemia (a-CML) and history of occupational exposure to petroleum products including benzene and other hydrocarbons. The t(5;10) (q33;q22) was found in 94% and 84% of metaphases in peripheral blood and bone marrow cells, respectively. Cytogenetic analysis of single colonies derived from granulocyte-macrophage (CFU-GM), and erythroid (BFU-E) hematopoietic progenitors showed that 88% and 40% of CFU-GM and BFU-E, respectively, had the t(5;10)(q33;q22). In contrast, peripheral blood T-lymphocytes, and cutaneous fibroblasts had normal 46,XY karyotype. Molecular analysis of the t(5;10)(q33;q22) translocation breakpoint is currently underway in order to identify genes located in this region which might provide insights into the pathogenesis of atypical myeloproliferative disorders.
