CORGI 2: A study to find genes that might increase or reduce the risk of bowel cancer Colorectal cancer (CRC) remains an important cause of morbidity and mortality. Identifying those at higher risk is important in targeting preventive measures, such as screening colonoscopy, to those most likely to benefit. Much of the risk of CRC and its precursor lesions (mostly polyps) is genetic, but a great deal of the heritability of CRC remains unexplained. Some of the remaining genetic risk probably results from rare genes with large effects, some from uncommon genetic variants with moderate effects and some from common differences with modest or very modest effects. The sub-division between these categories is extremely difficult to predict in advance of successful searches for these genes. The principal aim of this study is to identify additional susceptibility genes for CRC and cancers genetically related to CRC, such as endometrial cancer. This...
