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.
Uncovering The Impact Of Tandem Repeat Variation On Both Common And Syndromic Forms Of Paediatric Obesity

Funding Amount
$619,622.00
Summary
We are currently in the middle of a world-wide obesity epidemic. While much of the increase in obesity prevalence is due to diet and a sedentary lifestyle, a significant proportion of risk of childhood obesity is thought to have a genetic basis. A proportion of our DNA consists of repeated DNA units, like a genetic stutter, and the number of repeats is variable in the population. We will measure the repeat number at repeats across the genome to search for changes associated with obesity.
Molecular Networks And Genomics Of Host Response In Typhoid Fever

Funding Amount
$487,814.00
Summary
Typhoid fever affects 25 million people annually and is caused by systemic infection with Salmonella Typhi or Paratyphi. With this proposal, we will characterise how different individuals respond differently to typhoid, what ramifications this has for systemic Salmonella infection in humans, and how typhoid can be clinically identified early on, thus giving the patient the best possible chance to avoid complications, injury and potential death.
Mechanistic And Functional Drivers Of Neochromosome Evolution

Summary
Neochromosomes are Frankenstein chromosomes--massive extra chromosomes that are stitched together from 100s of pieces of normal chromosomes. They are found in 3% of cancers, but are common in some types, such as liposarcoma. We have mapped their structure and found they form through punctuated chromosome shattering and gene amplification. We will investigate the precise molecular mechanisms that cause this and the recurrent transcriptional and epigenetic drivers lead to their formation.
Black Death Genomics And The Evolution Of Pathogen Virulence

Funding Amount
$525,412.00
Summary
The Black Death was one of the most lethal plagues of antiquity and changed the course of human history. We will reconstruct and analyse the evolution of its causative agent – the bacterium Yersinia pestis – sampled from human skeletal remains dating back to the Black Death and beyond. We will determine the mutations that changed the virulence of plague epidemics through time, enabling a unique insight into the most dramatic example of pathogen emergence that has ever been available for study.
A Cohorts-based Approach To Define Monogenic Causes Of Mitochondrial Disease

Funding Amount
$824,841.00
Summary
New genomic technologies are transitioning from research to being used for routine genetic diagnosis. Rare diseases have been proposed to be one of the key beneficiaries of this translation. Collectively, rare diseases affect 6-8% of the population or ~20,000 births each year in Australia, mostly with serious health implications. Our study addresses the technical, bioinformatic and corroborative challenges needed for accurate diagnosis of a large group of rare diseases.
Determining Shared Genetic Control Of RNA Transcription Across 45 Human Tissue Types
Funder
National Health and Medical Research Council
Funding Amount
$264,684.00
Summary
There is strong evidence that much of the genetic susceptibility to disease acts through altering way genes are turned into proteins via RNA transcripts. One important problem in using transcriptomic data to study diseases is that the genetic control of RNA transcription is known to vary between tissues. This study will use new methods and RNA data from 45 human tissues to show the degree of common genetic control for each RNA transcript between each pair of tissues.
Using High-throughput Genomics To Reveal The Deleterious Genetic Changes That Underlie Paediatric Leukoencephalopathies
Funder
National Health and Medical Research Council
Funding Amount
$1,003,712.00
Summary
There has been an explosion of high-throughput DNA sequencing technologies in the past five years, which have the potential to completely revolutionise medicine and scientific research. Here we present a series of studies showing the successful application of this technology to children with genetic disorders of the central nervous system. This proposal seeks to expand this study to a large cohort of similarly affected paediatric patients.
Integration Of Genetic Testing For Risk Associated Genomic Variants And Rare Predisposition Genes Into The Management Of High Risk Hereditary Breast Cancer Families
Funder
National Health and Medical Research Council
Funding Amount
$645,457.00
Summary
Breast Cancer is a common disease with up to 20% of cases associated with a family history. This project aims to assess the contribution of recently identified risk associated genomic variants and rare predisposition genes to the heritability of familial breast cancer. The project will also assess the experience of clinicians and patients as we aim to use this information to help improve the process of risk assessment and genetic counselling in the specialist Familial Cancer Centres.
Gene Discovery In Motor Neuron Disease Through Systems Genomics

Funding Amount
$938,932.00
Summary
Motor neuron disease (MND) is an adult-onset, rapidly progressive neurodegenerative disorder that leads to paralysis and death, typically within 2 to 5 years of first symptoms. More than 85% of cases do not harbour known MND mutations. This proposal exploits genome-wide genetic and epigenetic profiling methods and leverages across multiple existing genomic resources to discover genes and functional pathways that contribute to MND pathogenesis and progression.
