Description:
The gene (E2A) that codes for proteins with the properties of immunoglobulin enhancer binding factors E12/E47 was mapped to chromosome region 19p13.2-p13.3, a site associated with nonrandom translocations in acute lymphoblastic leukemias. The majority of t(1;19)(q23;p13)-carrying leukemias and cell lines studied contained rearrangements of E2A as determined by DNA blot analyses. The rearrangements altered the E2A transcriptional unit, resulting in the synthesis of a transcript larger than the normal-sized E2A mRNAs in one of the cell lines with this translocation. These observations indicate that the gene for a transcription factor is located at the breakpoint of a consistently recurring chromosomal translocation in many acute leukemias and suggest a direct role for alteration of such factors in the pathogenesis of some malignancies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mellentin, J D -- Murre, C -- Donlon, T A -- McCaw, P S -- Smith, S D -- Carroll, A J -- McDonald, M E -- Baltimore, D -- Cleary, M L -- CA30969/CA/NCI NIH HHS/ -- CA42106/CA/NCI NIH HHS/ -- CA42971/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Oct 20;246(4928):379-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Stanford University School of Medicine, CA 94025.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2799390" target="_blank"〉PubMed〈/a〉
