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 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 se ....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 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.Read moreRead less

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

Summary
Breast cancer is the most common disease of women. In families with an inherited form of breast cancer, nearly half the women in every generation can develop the disease. The aim of this Australia-wide study is to collect clinical, epidemiological and genetic data on approximately 700 of these severely-affected families. This national resource will be of great value for researchers who want to identify and characterize the genetic and life-style factors that affect the onset and progression of t ....Breast cancer is the most common disease of women.

The aim of this Australia-wide study is to collect clinical, epidemiological and genetic data on approximately 700 of these severely-affected families. This national resource will be of great value for researchers who want to identify and characterize the genetic and life-style factors that affect the onset and progression of the disease. The data emerging from the study will lead to more accurate genetic counselling, better surveillance and, ultimately, better methods to prevent and treat the disease in families who inherit a predisposition to the disease.Read moreRead less

Summary
This proposal addresses the need to improve personalised treatment decisions for men with high risk familial prostate cancer as they have a very aggressive disease progression with a very poor clinical outcome. We will perform biological and pre-clinical studies to improve the clinical diagnosis, prognosis and treatment options for men with germline mutations in BRCA2 or BRCA1 genes who develop prostate cancer.
The human hepatitis B virus (HBV) is a member of the hepadnavirus family that includes a number of other very similar host-specific viruses. Acute HBV infection can produce extreme variation in disease, ranging from asymptomatic infection, to acute transient hepatitis with jaundice, or fulminant hepatitis leading to liver failure (Hollinger, 1996).

Acute HBV infection can produce extreme variation in disease, ranging from asymptomatic infection, to acute transient hepatitis with jaundice, or fulminant hepatitis leading to liver failure (Hollinger, 1996). The identification of viral genes that affect the severity of disease is a major current goal in medical virology. For example, there is considerable interest in identifying the genes of the influenza genome responsible for high mortality outbreaks; with the human immunodeficiency virus, the virus that causes AIDS, variants deleted in the nef gene region cause a less rapidly progressing infection and have attracted attention as a possible prototype for an attenuated vaccine. We propose to investigate how the different genes of hepadnaviruses affect the course of infection and type of disease produced. Studies will be performed in ducks infected with the duck hepatitis B virus (DHBV) as these animals provide the only model system available in Australia. We will study both experimentally and naturally derived DHBV variants to explore the effects of genetic changes on the outcome of infection. This will enhance our understanding of this virus family and will provide models for comparison with HBV infection. This knowledge may then contribute to our ability to manage and control HBV disease in humans.Read moreRead less
STICs And STONes: A Randomised, Phase II, Double-Blind, Placebo-Controlled Trial Of Aspirin In Chemoprevention Of Ovarian Cancer In Women With BRCA1 And BRCA2 Mutations

Summary
Women with a BRCA1 or BRCA2 gene abnormality are at increased risk of ovary and fallopian tube (O&FT) cancers and often have their O&FTs removed to prevent cancer. Microscopic cancers are often seen at the time of surgery. Some studies suggest that aspirin might reduce O&FT cancer risk. This study will assign women to daily aspirin or placebo for 6-24 months before their preventive O&FT surgery. It will provide a better understanding of how O&FT cancers start and the influence aspirin may have.
