Brief description Aims: 1. Develop a model that will predict who has a mutation in a group of genes that cause cancer 2. Estimate risk of cancer in people who have a mutation in these genes (carriers) 3. Determine if cancer risk in carriers can be reduced People who inherit a mutation in a group of genes called 'mismatch repair genes' are at increased risk of cancer, particularly cancer of the colon and rectum. If these carriers can be identified they can take preventive measures such as screening to reduce their risk of cancer and death. We will develop a model using data from the Colon Cancer Family Registry (CFR), the world's largest dataset of carriers and non-carriers which has already recruited and genetically tested over 4,000 families from Australasia, USA and Canada. The model will allow clinicians to predict who is a likely be a carrier based so they can be tested for the mutation. We know the risk of cancer is high in carriers, but we don't have precise estimates. We will use the Colon CFR applying sophisticated statistical methods required to answer this question. This data is critical for genetic counselling so appropriate decisions can be made by the patient and the doctor as to what preventive measures to take. We will also use the Colon CFR data to find out what how the carriers who develop cancer differ from those who stay cancer free using their completed lifestyle questionnaires which includes questions on diet, smoking, alcohol consumption, exercise, aspirin use, and oral contraceptive pill use. We may identify risk factors that carriers can avoid (or take up if they reduce cancer risk) to reduce their risk of cancer.
