Summary
Finding genetic causes of epilepsies is essential for refining treatments and genetic counseling. Genetic mutations may occur after fertilization (somatic mutations). These can be difficult to detect by routine genetic tests. We aim to identify somatic mutations by: very deep sequencing of blood to find low concentrations of mutations, analysing DNA from the cerebrospinal fluid, and analysing DNA obtained from the back of the nose which is closely related to brain tissue.
A Worldwide Study Of Cancer Risk For Lynch Syndrome

Funding Amount
$710,761.00
Summary
People with the genetic Lynch syndrome are more likely to get cancer but we cannot accurately predict who will get cancer and when. Doctors need this information to improve cancer prevention. Large collaborative studies are needed for this research. We have agreement from the 115 researchers to combine, into a single resource, 8,863 family trees of Lynch syndrome. We will analyse this data to determine the risk of cancer and whether it differs by sex, age, or nationality.
A Functional Assay To Classify Genetic Variants In Lynch Syndrome

Funding Amount
$368,195.00
Summary
At least one person in every 1000 is affected by Lynch syndrome, in which faulty DNA repair machinery causes high rates of cancer. People with Lynch syndrome can have their risk of cancer cut substantially with regular screening. However, we often struggle to understand whether people with 'non-standard' DNA sequences in particular genes actually have Lynch syndrome. This project develops a simple test that will tell clinicians whether a given sequence change relates to Lynch syndrome or not.
Expanding Diagnostic Approaches For Lynch Syndrome

Summary
Currently, there are ~1,000 families who have attended Family Cancer Clinics across Australia who have the hallmarks of having Lynch syndrome, a hereditary bowel cancer syndrome, but who have no gene defect identified, i.e. their cancer is unexplained. Clinicians are challenged by these “Lynch-like” patients as their family cancer risk is unknown. Our research has identified new gene defects in Lynch-like patients. Our aim is to optimise clinical testing approaches for Lynch-like patients.
Examining The Contribution Of Mutant DNMT3a In The Development And Sustained Growth Of Acute Myeloid Leukaemia

Funding Amount
$820,880.00
Summary
Experimental models of Acute Myeloid Leukaemia (AML) have been valuable tools for studying this cancer. Recent analysis of human cancer genomes identified novel mutated gene products implicated in AML. To study the involvement of these genes in the development and sustained growth of AML, we will generate new experimental models that express the mutated forms of these newly described genes. These studies will assist in the development of improved treatments for patients with AML.
Stress-induced Genomic Instability As A Driver Of Adaptive Responses In Human Cancer Cells

Funding Amount
$690,426.00
Summary
Growing experimental evidence suggests human cancer cells use evolutionary conserved programs to regulate their mutation rates in response to pharmacological agents, accelerating adaptation and the emergence of resistance. The purpose of our study is to identify the common molecular pathways and genetic mechanisms driving the regulation of mutation rates. Targeting of these pathways using a new generation of “anti-evolution” drugs is an attractive possibility for novel therapeutic approaches.
The Calcium Channel TRPV4 In Skeletal Development And Arthritis

Funding Amount
$683,069.00
Summary
We have discovered that mutations in a calcium channel gene, TRPV4, cause an inherited osteoarthritis in the hands and feet. This work suggests that TRPV4 may be important in osteoarthritis and suggests the exciting possibility that modulating TRPV4 activity may provide a new therapeutic approach for arthritis. We will study how and why the mutations disrupt channel function and study mouse models to see if they are more or less susceptible to arthritis.
Young Adult Myopia: Genetic And Environmental Associations
Funder
National Health and Medical Research Council
Funding Amount
$809,271.00
Summary
Myopia affects 80% of school leavers in the cities of East Asia, 45% of Asian Australian school leavers and is probably on the rise in European Australian adolescents. Increased levels of education and lack of time outdoors are known to increase the risk of myopia. We will examine 2,000 young adults to find the genes that interact with these risk factors. In addition to confirming when these risk factors are most important, identifying molecular pathways opens the avenue of new treatments.
Modelling TRPV4 Skeletal Disorders Using Human IPSCs

Funding Amount
$1,171,187.00
Summary
Inherited skeletal disorders are a significant disease burden. Many gene mutations have been defined but we only have limited understanding about how they cause the disease. We will use patient skin cells and new in vitro re-programing technology to induce them to form cartilage cells to produce “disease in a dish” models of human skeletal disorders. These models will allow us to answer questions about how specific mutations cause disease and identify potential therapies
Genome-wide Association Study (GWAS) For Juvenile-onset Myopia And Its Component Measures To Identify Molecular Pathways To Prevent Myopia
Funder
National Health and Medical Research Council
Funding Amount
$495,364.00
Summary
We will examine 2,000 young adults from the Western Australian Raine Cohort at the Lions Eye Institute / University of Western Australia. Ocular data will be collected relating to myopia (short-sightedness) and will be combined with extensive previous childhood and genetic research data collected on the Cohort, to investigate the genetic and environmental factors predisposing to myopia. This will assist in understanding the factors leading to myopia.
