Summary
In 1990 we set up a long-term study of diet and health. The aim was to measure diet and other risk factors in healthy people in order to see how they might affect future development of cancer. To do this we recruited 41,500 people aged 40 to 69, measured what they ate and drank, and collected information on other aspects of lifestyle, medical history, and family history of common diseases. All had height and weight and blood pressure measured and gave a blood sample. People were selected so that ....In 1990 we set up a long-term study of diet and health. The aim was to measure diet and other risk factors in healthy people in order to see how they might affect future development of cancer. To do this we recruited 41,500 people aged 40 to 69, measured what they ate and drank, and collected information on other aspects of lifestyle, medical history, and family history of common diseases. All had height and weight and blood pressure measured and gave a blood sample. People were selected so that men and women and migrants from Italy and Greece would be included. In this way we could widen the range of dietary habits, other lifestyle factors and genetic variation (measured in DNA from blood). Since then participants have completed another questionnaire and instances of disease have been noted from self reports and from examining medical records. We want to analyse data from 700 men in the study who have developed prostate cancer (PC). First we will analyse data collected on all 17,000 men (collected when joining the study, and at follow up). Next we will use data from only the 700 men with PC and 1400 men who have not developed PC. This study will focus on measuring substances in the blood. We want to measure a range of fats, vitamins, antioxidants and phytoestrogens, as well as male sex hormones and related substances. In the DNA from the blood we plan to measure variations in genes that influence how male sex hormones and other growth factors important in the prostate are produced and used. We will then be able to estimate what affect these factors have on the risk of getting PC. We will also be able to see if any of them act together to make the risk of PC much higher in certain men. This work should identify what lifestyle factors could reduce the risk of PC. It should also identify what genetic variations are associated with increased risk of PC and thus identify a sub group of men who might benefit from early medical attention or from changes in lifestyle.Read moreRead less
Early Versus Delayed Therapeutic Venesection For The Prevention Of Hereditary Haemochromatosis

Funding Amount
$196,012.00
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.
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.
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.
Common Susceptibility Genes Underlying The Idiopathic Generalized Epilepsies (IGE) - A Genome-wide Scanning Approach

Funding Amount
$212,063.00
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.
