This study investigates how much an individual's genes and environment account for the wide variation in brain structure and function. Using brain imaging we examine in what way the connectivity of the brain of identical and non-identical twins is the same or different from that of their co-twin, and carry out analysis of their DNA to identify some of the genes involved. This will provide fundamental information on genetic mechanisms influencing variation in brain structure and function.
In the study of common disease, it is becoming apparent that it is not only an individual's DNA sequence that can encode susceptibility to disease, but also chemical modifications to that sequence. Despite the importance of these chemical modifications in the development of disease, there has been no comprehensive survey of the extent which they are transmitted across generations in humans. This proposal will investigate how one of those modifications, DNA methylation, is inherited.
Exome Sequencing By NGS To Identify Rare Variants Affecting Type 2 Diabetes

Summary
Rates of type 2 diabetes are rising dramatically, and current efforts are failing to stem its progression. More information about why the disease develops is urgently needed. We apply the latest technological innovations in DNA analysis to accelerate the discovery of the mechanism behind the development of type 2 diabetes. This knowledge will lead to new ways to control diabetes through development of novel therapies.
CAGE: Consortium For The Architecture Of Gene Expression

Summary
This research project is about understanding why some people are most susceptible to disease than others, by identifying genetic factors that influence the expression of genes that are important in disease. We will work with leaders in the field in Europe and the USA in an international research consortium to find genetic variants with an effect on gene expression and to link those genetic factors to disease. The project will provide new understanding about the biological basis of common disease ....This research project is about understanding why some people are most susceptible to disease than others, by identifying genetic factors that influence the expression of genes that are important in disease.

Strengthening The Evidence Foundation For Public Health Guidelines

Funding Amount
$987,647.00
Summary
Public health guidelines should be based on rigorous evidence. If underlying studies are not sound, guidelines will not be credible or implemented. Dietary guidelines have been criticized for being biased. Our group studies bias across the whole research process – from the questions asked to the final publication. This project will measure the influence of bias at all stages in nutrition research in order to improve the evaluation of this research and the evidence base for dietary guidance.

Summary
Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia. We will examine the relationship between the form, structure and colour of existing types of moles and their subsequent risk of developing into melanoma. This study will combine dermoscopy, a non-invasive examination technique, with DNA tests of the genes that determine number of naevi, skin, hair and eye colour, aiding in the early prediction and diagnosis of skin c ....Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia.

Identification Of Parkinson's Disease Genes In Queensland Families Showing Patterns Of Mendelian Inheritance.

Funding Amount
$466,759.00
Summary
In rare cases, Parkinson's disease can be inherited through the generations of a family and it is possible to identify genetic changes that lead to this type of disease. This project aims to use new genetic sequencing technologies in several Australian families with inherited PD to find new genes that cause disease. This research will not only help these families but will teach us more about the reasons brain cells degenerate in this condition and other similar age-related brain diseases.
Neurodevelopment During Adolescence: A Longitudinal Imaging Study

Funding Amount
$1,706,589.00
Summary
Adolescence is a risk period for the emergence of psychiatric disorders. It is also a time of rapid change in the brain, but few studies have detailed changes in neurodevelopment during this sensitive period. We will study twins from early adolescence and use brain imaging to investigate changing brain patterns as the brain matures, and thereby, gain insight into factors responsible for increasing our risk or resilience for major mental health conditions and optimal points for intervention.

Summary
Our aim is to identify genes influencing common diseases including melanoma, asthma and cardiovascular disease. We measure adolescent twins for moliness, skin, hair and eye colour and a variety of blood traits. We have already found new genes for mole count, eye colour, skin damage, and several different blood cell types. For each of these disease traits there are many more genes to be found and these will inform new treatments. We plan to genotype 600 new families (2000 individuals) to help ach ....Our aim is to identify genes influencing common diseases including melanoma, asthma and cardiovascular disease.

We have previously made the most widely used animal brain atlas in the world. This atlas based on stained histological sections of the rat brain. In recent years, advances in MRI have made it possible to generate images of the rat brain at very high resolution. We have obtained a very high quality MRI image set from colleagues in Duke University in the USA, and we have begun to map these images in great detail, using our histological atlas as a guide.
