Summary
The major genes that predispose to hereditary breast cancer are called BRCA1 and BRCA2. Most mutations in these genes cause the protein product to be truncated and inactive. However there are many families in which such truncating mutations are not found, but instead there are sequence changes that may slightly alter the protein product. It is often difficult to predict whether these sequence variants are likely to cause hereditary breast cancer simply by looking at the position and nature of th ....The major genes that predispose to hereditary breast cancer are called BRCA1 and BRCA2. Most mutations in these genes cause the protein product to be truncated and inactive. However there are many families in which such truncating mutations are not found, but instead there are sequence changes that may slightly alter the protein product. It is often difficult to predict whether these sequence variants are likely to cause hereditary breast cancer simply by looking at the position and nature of the sequence change. Consequently, it is not possible to offer informative genetic counselling to these women or their at-risk family members. Assessment of the potential pathogenicity and functional significance of these unclassified sequence variants will be directly useful with regard to the clinical management of these women and their families, and will develop our current understanding of how different domains of these genes contribute to their role as cancer susceptibility genes. In addition, some of our experiments to classify variants may be useful as a screening tool to identify carriers of mutations, and so prioritize them for mutation screening.Read moreRead less
New High-risk Variants For Colorectal Cancer: The Post-GWAS Era

Summary
Our aim is to discover new genes that greatly increase bowel cancer risk. If we can identify these carriers we may be able to prevent them getting cancer. By studying DNA related to bowel cancer, using a novel family design, we will identify families most likely to carry the new genes. We will focus genetic testing, using new techniques, to look for mutations in these prioritised families. Identified mutations will be tested in a 3,500 bowel cancer cases to see how important they are.

Summary
Cancer development is associated with changes in the genetic composition of the cell. These changes involve the loss/gain of genetic material and/or changes in gene expression. Using sophisticated technology, we will define the changes in the genes that are associated with the transition from a benign to a malignant cancer state. We will examine this process in the blood cancer, multiple myeloma, in order to identify new treatment targets for this incurable disease.
