Evidence for a novel exon in the coding region of the adenomatous polyposis coli (APC) gene
- Univ. of Toronto (Canada)
Germline mutations of the tumor suppressor gene APC cause familial adenomatous polyposis. Somatic APC alterations are involved in several sporadic neoplasma, including colorectal, duodenal, gastric, and esophageal carcinoma. The APC mRNA is encoded by 15 exons. Additional transcripts have been reported, due to alternative splicing of coding as well as noncoding regions. Two mRNA isoforms occur due to a deletion of exon 7 or a partial deletion of exon 9. We have identified a novel exon, flanked by APC exons 10 and 11, which is expressed as an alternatively transcribed product of the gene. Further, we have shown that the novel exon consists of a heptad repeat motif and is conserved across species. 18 refs., 2 figs.
