Si. Papadhimitriou et al., AN UNUSUAL CYTOGENETIC ABNORMALITY INVOLVING CHROMOSOME-1 AND CHROMOSOME-7 IN A CASE OF CHRONIC MYELOMONOCYTIC LEUKEMIA, Cancer genetics and cytogenetics, 85(1), 1995, pp. 75-77
We report a case of chronic myelomonocytic leukemia in which cytogenet
ic analysis revealed a 47,XY, +1, +der(7)del(7)(q32q36)ins(7;1)(q32;p3
6.3p22) chromosomal constitution. This abnormal karyotype, which as a
whole is new to any myeloid malignancy, points to a possible pathogene
tic role for the oncogenes MET and FGR on the derivative chromosome 7,
and for the CSF1 and JUN genes flanking the breakpoint on chromosome
1.
