NCIt definition : Human PBX1 wild-type allele is located in the vicinity of 1q23 and is approximately
296 kb in length. This allele, which encodes pre-B-cell leukemia transcription factor
1 protein, is involved in transcriptional regulation. A chromosomal translocation
t(1;19)(q23;p13.3) of this gene and the TCF3 gene is associated with pre-B-cell acute
lymphoblastic leukemia. A second translocation of this gene and the EWSR1 gene may
be associated with myoepithelioma.;
