Colorectal Cancer Gene Identified By Case Western Reserve University Researchers
Case Western Reserve University School of Medicine researchers published a study in The American Journal of Human Genetics identifying the hereditary components of colorectal cancer (CRC.) “Identification of Susceptibility Genes for Cancer in a Genome-wide Scan: Results from the Colon Neoplasia Sibling Study” is the first large linkage study of families with CRC and colon polyps in the country. Because only five percent of CRC cases are due to known gene defects, this NIH-funded study is designed to identify the remaining CRC-related susceptibility genes. The team built on a previous study which identified a specific region on chromosome 9q that harbors a CRC susceptibility gene. Upon review of a whole genome scan of all chromosome pairs in 194 families, the researchers were able to identify additional CRC gene regions on chromosomes 1p, 15q, and 17p.
