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.
Diagnosis Of Inherited Genetic Disorders Using DNA Reference Standards

Funding Amount
$690,820.00
Summary
Whole genome sequencing can diagnose mutations that cause inherited disease, however, errors during sequencing and analysis can result in incorrect diagnosis. We propose to develop synthetic DNA standards that mirror important disease-associated mutations. These DNA standards are then added directly of a patient DNA sample and act as internal controls during sequencing and analysis to provide more accurate and reliable diagnosis.
A Study Of The Role Of Voltage-gated Potassium Channels In The Process Of Phototransduction, In The Setting Of Photoreceptor Sensitivity Levels And Response Times, And In The Progression Of A Distinctive Form Of Inherited Retinal Dystrophy

Funding Amount
$360,371.00
Summary
Inherited retinal disease is a major cause of blindness but the genetic basis is extremely heterogeneous. One such disorder, cone dystrophy with supernormal rod ERG, arises from mutations in KCNV2 that encodes a potassium voltage-gated channel protein. The objective of the project is to use animal models of the disease to determine the role of this channel protein in normal visual function and to assess the impact of loss of function on retinal development and function.
Defining The Leukaemogenic Mechanism For GATA2 T354M, A New Predisposing Mutation In Familial MDS/AML

Funding Amount
$631,883.00
Summary
A successful approach for identification of cancer genes has been to study the 5-10% of cases occurring in families with inherited predisposition to develop cancer. Unlike solid tumours, few cancer-causing mutations are known for haematological cancers. We have found a new mutation in 3 families in a gene (GATA2) not previously associated with familial acute myeloid leukaemia. We will explore how this mutation causes leukaemia to help better understand the more common non-inherited leukaemias.
Development Of A Bioinformatic Tool For The Rapid Identification Of Candidate Disease Genes

Funding Amount
$436,367.00
Summary
Candidate disease gene prediction systems assist geneticists by using biological data to suggest genes likely to be causative of diseases in regions of the genome delineated by genetic studies. This area has been enabled by completion of the Human Genome Project and increased availability of high-throughput experimental data and sophisticated bioinformatic tools. Identification of disease genes will contribute to an understanding of disease, as well as its prevention, diagnosis, and treatment.
How The Environment And Epigenetics Affect The Brain Disease Gene, MAPT.

Summary
Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether thi ....Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether this process will have an impact on these diseases.Read moreRead less
Defining The Changes In Cell Biology Caused By PRESENILIN Truncations Associated With Different Diseases

Summary
Truncations of the PRESENILIN genes in humans can cause two very different diseases: inherited, early onset Alzheimer’s disease (familial Alzheimer's disease) and a skin disease named inherited Acne Inversa. One truncation is also involved in the non-inherited, late onset form of Alzheimer’s disease. Why do these different truncations produce different diseases? Investigating this question will teach us more about the molecular bases of these different diseases.

Human Olfactory Neurosphere-derived Cells: A Novel Cellular Model For Parkinson's Disease.

Funding Amount
$365,126.00
Summary
ParkinsonÍs disease (PD) is an incurable, brain disease that affects 75,000 Australians with great societal cost. We are working on adult stem cells called (hONS) grown from peopleÍs olfactory mucosa (in the nose) as a research tool to study PD. Our project examines differences seen in hONS from people with PD and determines how certain cellular processes impact on the function of these cells. This work will enhance our understanding of the biology of PD and identify new targets for therapies.
Functional Analysis Of Recently Identified Novel Glaucoma Genes.

Funding Amount

Summary
Glaucoma is the commonest cause of irreversible blindness in the world. Recently, through genetic studies in cohorts of blinding glaucoma cases from Australia, our group has found that variants in two genes increase the risk of blinding glaucoma. This project will investigate how these genes contribute to pathological changes in the optic nerve and retina, at the back of the eye, that lead to glaucoma. This knowledge will be useful for developing new strategies to treat glaucoma.
New High Thoughput Animal Models To Investigate Amyloid Beta Toxicity

Funding Amount
$402,223.00
Summary
Amyloid-beta is widely considered to cause Alzheimer’s disease. The majority of amyloid-beta in Alzheimer's disease brains is found as shortened forms. The role of these shortened forms is uncertain and are not being tested in current animal models. We propose to develop new models to determine and compare their respective toxic effects, and to use these new models to help identify drugs to treat Alzheimer's disease.
