Summary
Allergies and chronic respiratory diseases are major causes of illness and death in Australia. Worryingly there are still many gaps in knowledge on how best to prevent and manage these diseases. The proposed program will investigate these questions and provide evidence to guide health policy and clinical management. As this program is built on state-of the-art methods and technology, these original Australian findings will be of great importance internationally.
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

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

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.
One of the current challenges in public health is to translate the progress from the Human Genome Project into reduced morbidity and mortality from disease. Once genetic defects are characterised, knowledge about the variability in severity of disease in mutation carriers, is important from a public health perspective.

Once genetic defects are characterised, knowledge about the variability in severity of disease in mutation carriers, is important from a public health perspective. Hereditary Haemochromatosis (HH) is a common genetic disorder of iron overload that results in a wide spectrum of disease, varying from non-specific symptoms to severe damage to liver, heart, pancreas and joints from iron deposition. It is easily treatable by regular blood donation, and population-based screening for HH has therefore been advocated. In this study we aim to address gaps in the existing data on HH regarding dietary and lifestyle factors that contribute to the variable clinical picture of HH. The study will be based on the Melbourne Collaborative Cohort Study, a cohort of 31,500 men and women who have been followed for approximately 10 years. Information on dietary and lifestyle factors was collected at initial enrollment, along with a blood specimen. We will test all non-Southern European participants (31,176) for the common HH mutations in the HFE gene and then select a subgroup of 1150 people, including all people with the main genetic defect as well as a comparison group, for further clinical followup. Participants will have genetic counselling and informed consent will be obtained. Participants will complete a short questionnaire and give a blood sample for measurement of iron overload, liver function, and other relevant blood tests, then undergo a brief clinical examination. Results of all tests will be given at a followup visit by genetic counsellor or physician. This study will provide important data on natural history of HH risk factors that influence variability in clinical presentation and the association of HFE mutations with chronic diseases and all cause mortality.Read moreRead less
Cancer And Low-dose Radiation - Possible Effects Of CT Scans In Childhood

Summary
Despite 100 years of research there is uncertainty about effects of low dose radiation from background and medical X-rays. We will measure the incidence of cancer in Australians exposed to CT scans (medical X-rays) as children between 1985 and 2005. Our results, from follow-up to 2009, will show whether there is a small but signicantly increased risk of cancer and guide further improvement in radiation safety standards if these prove to be necessary.
Genes And Environment In Late AMD: Pooling A State And Population Resource

Funding Amount

Summary
This study will pool cases from the West Australian Macular Degeneration database with the Blue Mountains Eye Study (NSW), to investigate the interplay of genes and environmental factors on risk of age-related macular degeneration (AMD), in particular the late, vision threatening stage. It will provide insights into the underlying causes of AMD, and could allow us to target people with AMD susceptibility genes for preventive approaches, which could reduce the burden of this disease.
Environmental And Genetic Factors In Childhood Acute Lymphoblastic Leukaemia: A Case-control Study.

Summary
In most countries, acute lymphoblastic leukaemia is the commonest cancer in children. One in 2000 children will develop this disease before their 15th birthday. New methods of treatment introduced over the last 30 years have resulted in cure for many children. However, one third of children diagnosed with this type of leukaemia still die and, even in those whose lives are saved, cure is achieved at a significant cost to the child, the family and the community.

One in 2000 children will develop this disease before their 15th birthday. New methods of treatment introduced over the last 30 years have resulted in cure for many children. However, one third of children diagnosed with this type of leukaemia still die and, even in those whose lives are saved, cure is achieved at a significant cost to the child, the family and the community. Greater understanding of the development of childhood leukaemia may lead to preventive measures. Most children with this type of leukaemia are very young, suggesting that factors to which parents are exposed may affect future children. For this reason, as well as investigating the health and lifestyle of the child, it is essential to study the parents. Recent research suggests an association between the mother's intake of folate during pregnancy and her child's risk of developing the most common type of childhood leukaemia. It is also apparent that genetic differences result in varying abilities to deal with toxins, which may alter the risk of developing some cancers. Diet and lifestyle probably also affect this risk. These observations and interactions need to be examined in greater detail. In this large Australia-wide study specific genes will, for the first time, be examined and analysed in conjunction with rigorous assessment of exposures thought to be related to the development of childhood leukaemia. Results obtained from children with leukaemia and their parents will be compared with those from healthy children and their parents. This study is unique in its attempt to assess gene-environment interactions in Australian children and their parents. It will clarify the role of folate and other potential environmental agents in the development of childhood leukaemia and examine gene variations that may affect cancer risk.Read moreRead less

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.
