Summary
This study will investigate treatment by blood removal for the inherited iron overload condition hereditary haemochromatosis: Is treatment more effective in reducing risk of disease if performed early as a preventive measure rather than later after diagnosis with symptoms? Details of the lifetime history of blood donation from the Australian Red Cross Blood Service will be combined with existing information from questionnaires and clinical examination of 1,439 study participants in Melbourne.

Summary
Recent research internationally has revealed that development of the fetus during pregnancy is related to later risk of hypertension and diabetes. Low birth weight infants have higher risk. While research has shown that this can't entirely be explained by genes, it is possible that some genes amplify the effect of low birth weight. This project seeks to identify such genes by examining a set of likely candidates. The targeting of these genes has been based on the knowledge that hypertension and ....Recent research internationally has revealed that development of the fetus during pregnancy is related to later risk of hypertension and diabetes. Low birth weight infants have higher risk. While research has shown that this can't entirely be explained by genes, it is possible that some genes amplify the effect of low birth weight. This project seeks to identify such genes by examining a set of likely candidates. The targeting of these genes has been based on the knowledge that hypertension and diabetes are generally more common in populations that have evolved in the tropics and have more melanin pigment in their skin. The focus in this study, therefore, is on genes that are known to be more common in these populations and also appear to affect risk of blood pressure and diabetes.Read moreRead less

Summary
Chronic diseases such as coronary heart disease, breast cancer, prostate cancer and non-insulin dependent diabetes are responsible for a significant burden of ill-health in society. Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors. The findings have implications for health promo ....Chronic diseases such as coronary heart disease, breast cancer, prostate cancer and non-insulin dependent diabetes are responsible for a significant burden of ill-health in society. Studies of familial aggregation are important in determining the relative magnitude of genetic and lifestyle-environment factors associated with chronic diseases, and in identifying individuals and families at high risk, even in the absence of conventional risk factors. The findings have implications for health promotion in the general population and disease prevention in those identified to be at high risk. An outstanding characteristics of these studies is that many participants had an event at some unknown time before the entry. This project aims at adapting current methods to properly account for events before entry and to provide estimates of familial aggregation between parents, between children and between parents and children in the same model. Furthermore, it provides freely available software for proper familial analyses which have not had any feasible numerical methods (or software). In addition, it provides estimates of familial aggregation of coronary heart disease in Busselton families which has longer follow-up than most other studies. This project is very cost effective as the Busselton Health Study consists of a series of cross-sectional surveys since 1968 and currently has hospital morbidity and death follow-up from medical record linkage until the end of 1997.Read moreRead less
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

Funding Amount
$150,679.00
Summary
Excessive sunlight can cause melanoma, a serious type of skin cancer. However, there are other factors including a person's genetic make-up that are thought to put some people at higher risk. Many 'healthy' people have small changes in their genes that might make them more likely to develop melanoma. We need to know more about these genetic factors. Our study will investigate how particular small genetic changes influence a person's likelihood of developing melanoma.
Genes And Environment In The Risk Of Early Age-Related Macular Degeneration: A Population-based Case-Control Study

Funding Amount
$949,588.00
Summary
This study will pool data from three well-conducted population-based cohorts of older persons to gain a large sample size in order to investigate the interplay of genes and environmental factors on the risk of age-related macular degeneration (AMD). The study will give insights into AMD pathogenesis, and enable potential targeting of people with AMD susceptibility genes for preventive approaches. These could ultimately reduce the burden of this blinding condition.
Common Susceptibility Genes Underlying The Idiopathic Generalized Epilepsies (IGE) - A Genome-wide Scanning Approach

Summary
Epilepsy is the most common serious brain condition. Seizures affect about 10% of people at some time in their life and their consequences are an important public health problem. The most common group of inherited epilepsies account for about 30% of childhood epilepsy and 20% of adult epilepsy. This study will be the first in Australia and one of only a few worldwide to take a population-based approach to investigating the link between epilepsy and genetic inheritance.

Genetic And Environmental Epidemiology Of Early-onset Melanoma In The Australian Melanoma Family Study
Funder
National Health and Medical Research Council
Funding Amount
$412,210.00
Summary
This project will investigate the genetic and environmental causes of melanoma, especially melanoma developing under the age of 40 in Australian families. This project will help to identify which people are at greatest risk of developing melanoma, by identifying the genes involved in melanoma development and the contribution of environmental and lifestyle factors to the disease. We will also determine how much hereditary factors contribute to melanoma risk.
