Summary
As many as one in ten healthy individuals have big hearts. Careful scientific investigation has revealed that the bigger one's heart, the greater the risk of dying from cardiovascular disease. This is true even in the absence of known causes of heart disease. Unlike high blood pressure or cholesterol, the size of the heart is not easily measured and enlargement often goes undetected. We were among the first internationally to discover genetic clues to enlarged hearts. We identified regions on ra ....As many as one in ten healthy individuals have big hearts. Careful scientific investigation has revealed that the bigger one's heart, the greater the risk of dying from cardiovascular disease. This is true even in the absence of known causes of heart disease. Unlike high blood pressure or cholesterol, the size of the heart is not easily measured and enlargement often goes undetected. We were among the first internationally to discover genetic clues to enlarged hearts. We identified regions on rat chromosomes that harbour the gene or genes that influence heart size. The aim of these studies is to identify the exact gene responsible and to understand how that gene produces its effects. The experiments involve testing DNA samples already obtained from many hundreds of rats and breeding animals to study the consequences of the genetic abnormality in greater detail. The experiments are critical steps towards the prevention of big hearts and their complications in humans. In time, genetic tests will offer earlier detection and facilitate targeted and tailored treatments.Read moreRead less
Australian Genomewide Association Study In Osteoporosis

Summary
Osteoporosis is a common condition in which bone strength is reduced due to reduced amount and quality of bone. Reduced bone strength means an increased risk of fracture. Osteoporotic fractures occur in 1 in 2 women and 1 in 3 men in their lifetime, and the likelihood of suffering osteoporotic fracture increases with age. Most of the risk of developing osteoporosis is genetic, but few of the genes involved have been identified. Our goal is to identify those genes.
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.
Identifying Endophenotypes For Eating Disorders And Their Relationship To Specific Genotypes And Environments

Funding Amount
$507,419.00
Summary
Around 15% of Australian women will have an eating disorder at some time in their life, and half of these will experience significant levels of depression and suicidality. The current project seeks to build better models of the initiation and maintenance of eating disorders that can inform development of effective treatments, with identification of genes and environments that predict the various components that define eating disorders (i.e., behaviours, temperaments and cognitive flexibility).
