Funding Amount

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.
A Genome Wide Association Study For Endometriosis Susceptibility Genes

Funding Amount

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.
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.
QTL Linkage Analysis For Complex Human Traits In Twin Families

Funding Amount
$1,000,000.00
Summary
This project will focus on finding genes for common human diseases. Now that the human genome has been sequenced, the race is on to find out what the estimated 38,000 human genes do and which ones are associated with which diseases. Scattered throughout the genome are small variations in DNA sequence, some of which increase the odds of disease while others are protective.
Epigenetic Hyperglycemic Cell Memory Causes Vascular Complications In Type 1 Diabetes

Funding Amount
$332,140.00
Summary
This project seeks to identify how epigenetic change in response to hyperglycemia can cause vascular complications of diabetes, and how this contributes to “hyperglycemic memory”; a phenomena where cells may undergo gene modifications which increase risk to further complications later in a patients life. These studies are the first of their kind and will characterize the types of epigenetic change that can cause human disease.
Mechanisms of zinc transport and homeostasis in plants. Zinc deficiency is a widespread factor limiting crop production and affects many soils of southern Australia and around the world. Genetic techniques can be used to identify zinc-efficient crop breeds able to grow well under zinc deficient conditions and able to efficiently deliver zinc to cereal grains to alleviate nutritional zinc-deficiency in humans. This project will identify new genes important in zinc transport and homeostasis in pla ....Mechanisms of zinc transport and homeostasis in plants. Zinc deficiency is a widespread factor limiting crop production and affects many soils of southern Australia and around the world. Genetic techniques can be used to identify zinc-efficient crop breeds able to grow well under zinc deficient conditions and able to efficiently deliver zinc to cereal grains to alleviate nutritional zinc-deficiency in humans. This project will identify new genes important in zinc transport and homeostasis in plants and will ultimately allow their role in zinc efficient crops to be assessed. This will contribute to more rapid and directed strategies in breeding zinc efficient crops.Read moreRead less
Incorporating Genetic Information Into The Diagnosis And Treatment Of Cancers And Mental Health

Funding Amount
$123,502.00
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.
Collaborative Ovarian, Prostate And Breast Gene-environment Study (COGS)

Summary
The EU-COGS application has arisen from genome wide scans that identify common genetic variants associated with breast, ovarian and prostate cancer risk. Our studies contributed 50% of DNA samples to the prostate cancer genome wide scan. COGS will now measure these variants in a large number of cases and controls from an international consortium of studies to test whether genetic risks are modified by other genes or lifestyle factors. This will better define genetic risks and identify men at inc ....The EU-COGS application has arisen from genome wide scans that identify common genetic variants associated with breast, ovarian and prostate cancer risk. Our studies contributed 50% of DNA samples to the prostate cancer genome wide scan. COGS will now measure these variants in a large number of cases and controls from an international consortium of studies to test whether genetic risks are modified by other genes or lifestyle factors. This will better define genetic risks and identify men at increased risk who should be the focus of appropriate screening and prevention strategies. Australian participation in the prostate cancer genome wide scan helped to identify a number of genetic variants associated with prostate cancer risk. The aim of EU-COGS, which needs large numbers of samples with epidemiological, tumour pathology and clinical information, is to determine whether these genetic variants act singly or together and the extent to which lifestyle and environmental factors can modify the genetic risk. Our contribution of >10% of the total DNA samples to COGS will enable us to understand how such genetic risks can be modified in the Australian environmental context.Read moreRead less
