Resumen
Two novel chromosomal translocations were identified in 2 patients with chronic lymphocytic leukemia (CLL). Case 1: 60 year-old male, stage Rai 0/Binet A, with mutated immunoglobulin heavy (IgH) and lambda (Iglambda) light chain genes; karyotype: 46, XY, t(9;12)(q12;p11) [3]/ 46, XY [22]. Case 2: 56 year-old male, stage Rai 2/Binet B, with mutated IgH and unmutated Iglambda genes; karyotype: 46, XY, add(10)(q26), t(13;18)(q14;q21) [8]/ 46, XY [27]. Although both translocations are novel, the involved breakpoints (especially 13q14 and 18q21) have been reported to participate in various aberrations in CLL patients. Aberrations affecting bands 9q12 and 12p11, as in case 1, are generally rare.
