Summary
Radiation is an important therapeutic agent for the treatment of a variety of cancers. However, radiation also causes cancers, certainly at high doses but it remains unclear as to the threat from low dose radiation eg in the vicinity of radiation accidents and at high altitudes. A greater understanding of the threats of radiation exposure is possible from the study of a number of rare syndromes characterized by extreme sensitivity to radiation and predisposition to develop cancer.

However, radiation also causes cancers, certainly at high doses but it remains unclear as to the threat from low dose radiation eg in the vicinity of radiation accidents and at high altitudes. A greater understanding of the threats of radiation exposure is possible from the study of a number of rare syndromes characterized by extreme sensitivity to radiation and predisposition to develop cancer. The identification of new syndromes with radiosensitivity assists in delineating the overall response to radiation and the connection with cancer. This project is designed to identify the molecular basis of what appears to be a novel defect. It has some of the characteristics of a well described syndrome ataxia-telangiectasia (A-T), namely signs of neurodegeneration and sensitivity to radiation but the protein defective in A-T appears to have normal function in this case. A comprehensive investigation of a number of pathways of radiation signaling is planned to identify the nature of the defect.Read moreRead less
Many recent gene mapping efforts have focused on population based approaches instead of previously used family based approaches. One of the limiting factors with population based approaches is the cost of the technology - each participant must be evaluated (or genotyped) for hundreds of thousands of genetic markers. The cost can be reduced by using an approach which pools individuals together for genotyping, with statistical models used to deal with the problems that this creates.
Mapping Genes For Typical Migraine Using Twin Families.

Summary
Current evidence suggests multiple genes may underlie susceptibility to the more common forms of migraine. The project will look to see if the these genes provide clues to the further elucidation of the complex molecular pathways of migraine and will help in the development of diagnostic tests and evidence-based treatment strategies.

Incorporating Genetic Information Into The Diagnosis And Treatment Of Cancers And Mental Health

Summary
Genetic information could improve diagnosis and selection of treatment for conditions such as cancer and psychosis. This aim of this research is to improve methods for using family history to diagnose patients, and to identify some of the genes involved in response to anti-cancer and anti-psychotic medications. This type of information can then be used to determine which drugs patients should be prescribed before starting treatment.
A knockout approach to identifying genes involved in epidermal development and homeostasis. These studies will identify new genes which play a role in the development or maintenance of the skin, some of which may subsequently be shown to play a role in disease. The project capitalises on an investment of tens of millions of dollars by the Wellcome Trust in generating a significant cohort of knockout mice.

These studies will identify new genes which play a role in the development or maintenance of the skin, some of which may subsequently be shown to play a role in disease. The project capitalises on an investment of tens of millions of dollars by the Wellcome Trust in generating a significant cohort of knockout mice. Our involvement in this international initiative will ensure Australia's participation in a project at the forefront of mouse genetics, using cutting edge infrastructure and technologies to provide insights into the complement of genes involved in skin biology. Models of interest will be repatriated to Australia for further study capitalising on existing infrastructure provided through the NCRIS funding program. Read moreRead less
Genetic And Bioinformatic Analysis Of Complex Human Diseases

Summary
Some human diseases are common in families; examples include prostate cancer, blood cancers, epilepsy and diabetes. Therefore, close relatives of individuals with a disease have an increased risk of being affected by this disease, implying a genetic basis. Finding the cause of these diseases is difficult, we will be developing novel approaches to the identification of genes responsible for these diseases. This is the first step towards the development of treatments for affected individuals.
Genome-wide Association Studies Of Biomedical Traits And Endophenotypes For Complex Disease

Summary
The burden of common complex diseases, such as cardiovascular disease is substantial to the health care system. These diseases are caused by genes and environments as well as their interactions. The proposed project will identify genes affecting the susceptibility of individuals to complex diseases. Discovery of such genes will be important for their diagnosis, prevention and treatment and may serve as an important resource for future personalized medicine.

These genes are inherited from our parents and number around 100,000. Faults in these genes can cause inherited diseases such as cystic fibrosis, cancers and common disorders such as Asthma and diabetes. These genes need detecting so that particular genes can be identified as causing the disease and also so that patients can have their disease properly diagnosed so that proper therapy and information can be given to the patients. In future similar changes (but changes not causing disease) may be searched for in patients to overcome the side effects of drugs. Our centre specializes in the methods of detecting faults and their application. Two of our methods are being used around the world and one is being sold as simple kit. These methods still have drawbacks and the work proposed is to overcome some of these. We propose to apply our and other methods to faults in genes which have recently been shown to cause diseases of the artery. This is an exciting new development that shows that this disease is similar to cancer. We are fortunate to have attracted Dr Paula Bray from the laboratory which discovered this. This new finding needs to be studied in more detail and may identify life-style factors which cause coronary heart disease. Our studies will also assist in gene therapy when it becomes available.Read moreRead less
A Genome Wide Association Study For Endometriosis Susceptibility Genes

Summary
Endometriosis is a common condition that affects up to 10% of women. Symptoms are severe pelvic pain, menstrual problems and infertility with major impacts on women's lives and relationships. Since 1996, 4,000 affected women plus their families have joined our genetic study. Our aim is to conduct a genome wide search to identify genes contributing to endometriosis. This knowledge will ultimately lead to better diagnosis and treatment for the millions of women who suffer the disease.
