Funding Amount

Summary
Cancer of the vulva is 50 times more common in young Aboriginal women in Arnhem Land than in other women. Human Papillomavirus (HPV), which also causes cervical cancer, is the usual cause of this cancer; initial investigations have found that HPV is present in these cancers but is not the reason for the excessive incidence. This study will investigate local knowledge about this disease, and whether inherited susceptibility or an environmental cancer-causing substance are the cause of the excess.
Major Histocompatibility Complex (MHC) Genetics Of Ankylosing Spondylitis

Summary
Ankylosing spondylitis (AS) is the prototypic condition of a group of types of inflammatory arthritis called 'seronegative spondyloarthropathies'. These conditions are the most common form of inflammatory arthritis in white populations and occur worldwide. One third of the risk of developing AS is determined by genes within a region called the 'major histocompatibility complex' (MHC), in addition to the gene HLA-B27, the main gene causing AS. We aim to identify the remaining MHC genes.
The Immunogenetics Of Ankylosing Spondylitis: A Genetic And Functional Investigation Of IL23R And Related Genes

Summary
Ankylosing spondylitis (AS) is a common inflammatory arthritis which causes primarily back pain and stiffness, and affects 1-250 individuals. Our group identified association between tagging genetic markers in the gene IL23R and AS, and our preliminary data suggests some related genes are involved as well. This study aims to identify the key genetic variants involved and determine the mechanism by which they cause AS.
A Genome Wide Association Study For Alcohol And Nicotine Addiction Susceptibility Genes

Funding Amount
$872,816.00
Summary
Alcohol and nicotine addiction are major public health problems within Australia. As well as the personal and economic costs associated with dependence, there is a wide range of downstream health effects from heavy drinking and smoking. This is a proposal for a genome wide association study to systematically screen and identify genetic variants within the Australian population that affects an individual's liability to developing alcohol addiction, nicotine addiction or both.
Massively Parallel Sequencing And PCR Optimised For DNA-based Diagnostics And Discovery

Funding Amount
$201,664.00
Summary
The next generation of medical diagnostics and discovery in disease research will involve the marriage of PCR, a tool used to amplify large amounts of DNA from small starting quantities, and �next generation� sequencing, a way to sequence lots and lots of DNA on a single instrument run. This study aims to describe methods which allow scientists to screen hundreds of disease genes in hundreds of people simultaneously with high accuracy and high efficiency.
Environmental Risk Factors For Iron Overload-related Disease In A Cohort Study Of Hereditary Haemochromatosis

Funding Amount
$152,936.00
Summary
Results published last year from our Melbourne HealthIron study of hereditary haemochromatosis (iron overload disease) show that almost one third of the 50,000 men genetically at risk of iron overload in Australia will develop symptoms of disease including fatigue, arthritis and liver damage. We will use data from the recent follow-up of the Health2020 cohort, of which HealthIron is a sub-study, to determine environmental risk factors for progression to disease in people with iron overload.
Early Versus Delayed Therapeutic Venesection For The Prevention Of Hereditary Haemochromatosis
Funder
National Health and Medical Research Council
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.
Understanding The Cause And Consequence Of Impaired Insulin Secretion In The NZO Mouse A Model Of Diabetes.
Funder

Funding Amount
$711,224.00
Summary
Type 2 diabetes is a major health problem affeting over 1 million Australians. A key feature of this disease is reduced secretion of the pancreratic hormone insulin which results in high blood sugar levels. We are using a naturally occurring animal model of diates called the NZO mouse to understand why the pancreas secretes less insulin and the consequences of this defect. This project has the potential of providing better therapeutic strategies for patients with Type 2 diabetes.

Summary
Atopic dermatitis, or eczema, is an increasingly common severe allergic condition affecting the skin that afflicts up to 30% of all Australian children. Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well. A familial history of asthma or eczema is an important risk factors for a child developing the dis ....Atopic dermatitis, or eczema, is an increasingly common severe allergic condition affecting the skin that afflicts up to 30% of all Australian children. Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well. A familial history of asthma or eczema is an important risk factors for a child developing the disorder, meaning that allergy is to a large extent determined by the genes we inherit from our parents. Our genes consist of four different building blocks, called nucleotides, which are identified by four letters: A, G, C and T. Each gene has a specific spelling of these four letters, although between any two people there will invariably be small single letter differences in the way a gene is spelt. Normally, these differences have no effect. In an allergic individual, however, these differences do have an effect. Identifying differences in the way a gene is spelt and why this should lead to eczema or asthma is a major research goal. In the past several years a number of genes have been identified that play an important role in allergy and we have recently identified a spelling difference in a new gene that we believe is important in the allergic response of eczema and asthma. At the moment, we can only guess how this gene might work. We know it is expressed in cells of our immune system that are important in allergy. We also suspect it might be an on or off switch for other genes important for allergy. This project will test these ideas and show how differences in the way this gene is spelt lead to differences in how this gene works. This will be important in adding another piece to the puzzle of how genes control allergy and could lead to better and earlier treatment of these disorders with improved health for affected children as well as adults.Read moreRead less
