Brief description Approximately 1-2% of all large bowel cancers are thought to be caused by inherited defects in genes involved in the repair of DNA. These cancers are indistinguishable from those that occur in the general population and this has made it difficult to identify individuals and families with the defective gene. It has been estimated that only about 10-20% of individuals affected by this familial cancer syndrome are being referred to specialized genetic service centres for testing. The large majority of familial colorectal cancers occur in young patients aged less than 60 years at diagnosis. Identification of these cases would allow genetic testing to be carried out on other family members who might also carry the mutant gene, thus allowing regular surveillance and a far greater likelihood of early detection and therefore cure. The aim of this project is to use a relatively simple laboratory-based method to test for the possibility that colorectal cancer in young patients (<60 years) may be inherited. From our preliminary data we expect that about 2% of all large bowel cancers, or 20 cases per year in Western Australia, may be familial. These individuals will be referred to Genetic Services WA for proper evaluation of their family history for cancer and for further DNA testing in an attempt to identify the defective gene. For positive cases, affected family members could then be tested for the gene after appropriate genetic counselling.
