PG - 972-5 AB - Abnormalities of the short arm of chromosome 12 are nonrandom events in T cell prolymphocytic leukemia (T-PLL). Fluorescence in situ hybridization (FISH) studies were performed in three patients with T-PLL and one patient with T cell peripheral lymphoma and rearrangement of 12p. Whereas the rearrangements of 12p were different in the four patients, a breakpoint centromeric to the ETV6 gene was present in the three T-PLL patients. In addition, loss of heterozygosity for a chromosomal segment telomeric to ETV6 with loss of the RAD52 locus was also shown by FISH studies. In contrast, the breakpoint was telomeric to ETV6 in the patient with peripheral lymphoma. FAU - Salomon-Nguyen, F AU - Salomon-Nguyen F AD - INSERM U 301 and SD401 No. 301 CNRS, Paris, France.
