Amplifications of a region of chromosome 2p13 have been observed in various B-cell malignancies. After having ruled out several candidate genes, British, German and US researchers were able to identify the BCL11A gene and its 3 major RNA isoforms as the pathologic target for the amplification (Blood. 2001 Dec 1; 98(12):3413-3420). The researchers also reported that a previously identified translocation may contribute to deregulation of the BCL11A locus.
