Summary
Failure of the skin to close over the brain and spinal cord during human development results in the devastating congenital birth defects anencephaly and spina bifida, known collectively as the neural tube defects. These are the second most common congenital birth defects affecting 1:1000 pregnancies. Anencephaly is not compatible with life and affected babies die at birth. In contrast children with spina bifida survive, but suffer from limb paralysis, bowel and bladder dysfunction, learning diff ....Failure of the skin to close over the brain and spinal cord during human development results in the devastating congenital birth defects anencephaly and spina bifida, known collectively as the neural tube defects. These are the second most common congenital birth defects affecting 1:1000 pregnancies. Anencephaly is not compatible with life and affected babies die at birth. In contrast children with spina bifida survive, but suffer from limb paralysis, bowel and bladder dysfunction, learning difficulties and psycho-social disturbances. Our laboratories have identified a family of genes essential for the colsure of the neural tube in mammals. The aim of this proposal is to understand the mechanisms of action with a view to developing new therapeutics that mey be used preventatively in these conditions. We also hope that these studies may facilitate the development of a genetic test to screen couples at risk.Read moreRead less
Identifying The Critical Pathways Which Regulate Vertebrate Craniofacial Development

Funding Amount
$552,131.00
Summary
Understanding the genes which underlie human birth defects is of immense clinical importance. Our laboratory is a world-leader investigating a gene responsible for facial skeleton development, Grhl2. With our wide range of models, we will discover how Grhl2 works to ensure the face and skull develop properly during birth.
Population-based Data Linkage To Investigate The Health And Development Of Children Born After IVF

Funding Amount
$321,972.00
Summary
In Australia 1 in 25 births are conceived from IVF treatment and this is increasing. My research program will use a comprehensive set of linked population data to address key questions in the IVF field following major changes to IVF practice in the last decade. This research (examining fetal growth, birth defects, intellectual disability and school achievement) has the potential to influence clinical practice and will greatly improve the information available for pre-treatment counselling.
Recent Changes In IVF Clinical Practice: Data Linkage To Investigate Their Impact On Fetal Growth And Birth Defects.

Funding Amount
$219,076.00
Summary
In Australia 1 in 25 births are conceived from IVF treatment and this is increasing with the continuing trend towards later childbearing. This study will use linked population data to assess fetal growth and birth defects in IVF-conceived children following major changes to IVF practice in the last decade. There are limited data internationally on health outcomes following the use of more recent IVF techniques and insufficient data to allow for adequate pre-treatment counselling.
This study is aimed at identifying genetic variants that influence susceptibility to migraine. We plan to use DNA samples already collected from families with multiple migraine affected individuals and sequence a region on the X chromosome that has previously been identified as harbouring a migraine susceptibility gene. This project will identify gene(s) that contain variants contributing to migraine.
Development And Application Of A Mendelian Randomization Framework Aimed At Dissecting The Biological Basis Of Ankylosing Spondylitis And Other Complex Diseases

Funding Amount
$279,666.00
Summary
Our aim is to identify genes and biological molecules that cause a type of autoimmune arthritis called ankylosing spondylitis. Our approach involves finding combinations of genes that are related to biological molecules of interest and then testing to see whether the gene combination is also related to risk of disease. We hope that our strategy will lead to new drug treatments targeting the condition.
Finding The Genetic Causes Of Asthma: The Australian Asthma Genetics Consortium (AAGC)

Funding Amount
$1,697,639.00
Summary
Asthma is a major burden on individuals and health systems. Despite many decades of research, no major effective new treatments for asthma have emerged recently. We will establish a large international consortium to systematically test nearly all known human genes to identify those that influence asthma susceptibility. We expect to identify pathways not previously implicated in asthma and so lead to a potential breakthrough in the development of more effective treatments.
Evaluating The Genetic Contribution To Rheumatic Heart Disease Pathogenesis In Australian Aboriginal And Torres Strait Islander Communities

Funding Amount
$1,782,074.00
Summary
Rheumatic heart disease is highly prevalent in Aboriginal people in Australia and leads to early cardiac disease. Despite decades of research, the underlying genetic mechanisms for why it occurs are not well understood. We are conducting a genetic study to better understand why some people are susceptible to RHD and others are not. The study will involve substantial Aboriginal leadership and consultation and will be a model for the conduct of genetic studies in Aboriginal populations.
Novel Ways Of Utilizing Genome-wide DNA Methylation Data From Peripheral Blood Samples In Genetic Epidemiology

Funding Amount
$285,186.00
Summary
The aim of this project is to develop statistical methods and paradigms to better leverage the considerable amount of peripheral blood DNA methylation data that has been collected from large scale epidemiological studies. In particular, our focus is on developing and optimizing statistical methods of using DNA methylation profiles to “tag” environmental exposures, so that this information can be better utilized to investigate the genetic and environmental basis of complex traits and diseases.
Using Methods In Genetic Epidemiology To Elucidate The Relationship Between Viral Infection And Risk Of Autoimmune Disease
Funder

Funding Amount
$622,446.00
Summary
Autoimmune diseases occur when the body's natural defense mechanisms attack healthy tissues by mistake. It has long been thought that viral infections might play a role in triggering autoimmune disease. Our study aims to find genes that influence the body's response to viral infection and subsequently whether the same genes are involved in autoimmune disease pathology. If the same genes are important in both situations then this will provide evidence that viruses trigger autoimmune disease.
