Cancer Genetics

Summary

The Cancer Genetics Laboratory investigates why some people get cancer, and how these cancers, particularly those of the breast, ovary and stomach, develop from a normal cell. The laboratory also looks at why these cancers are often found together in the same families and share many similar characteristics.

We are looking for other genes that might predispose to breast or ovarian cancer, using families from the Australasian consortium of familial breast cancer, kConFab, to identify high-penetrance genes, and case-control studies to identify low-penetrance genes. In addition, the laboratory has recently begun studying an inherited form of gastric cancer which has never previously been described.

The laboratory also has an interest in genes involved in response to chemotherapy in ovarian cancer patients, and have done a genome-wide association study in cases from the Australian Ovarian Cancer Study, with validation in additional cases from the Ovarian Association Consortium.

Conditions researched

• Breast cancer
• Ovarian cancer
• Gastric cancer

Current research

• Genes involved in resistance to chemotherapy in patients with ovarian cancer
• The ATM gene as a breast cancer predisposition gene
• Genomic characterisation of familial breast tumours
• Next generation sequencing approaches to finding novel breast cancer susceptibility genes
• Somatic mutations in basal-like breast tumour
• Low penetrance breast and ovarian cancer susceptibility genes, and modifier genes for BRCA1 and BRCA2
