we have cloned the chromosomal joinings between chromosomes 11 and 14 and also between chromosomes 14 and 18 , in b-cell tumours carrying translocations involving these chromosomes , and suggested the existence of two translocated loci , bcl-1 and bcl-2 , normally located on chromosomes 11 ( band q13 ) and 18 ( band q21 ) respectively , involved in the pathogenesis of human b-cell neoplasms .
