Summary
The overall aim of the project is to employ a rat model to investigate neurodegeneration in patients with ataxia-telangiectasia (A-T). Ataxia-telangiectasia is a complex multisystem disorder characterised by progressive neurological impairment, variable immunodeficiency and cancer predisposition. The rat model recapitulates the neurodegeneration in patients and thus this project will provide important insight into the nature of the defect as well as approaches for the treatment of the disorder.

Summary
New therapeutic targets for migraine are desperately needed. Although studies have identified some migraine genes there remains considerable underlying genetic variation to be characterised. This study aims to identify functional variants in the mitochondrial genome that contribute to migraine susceptibility, utilising the isolated Norfolk Island population. Outcomes will determine the significance of the variants identified, potentially leading to new diagnostics.
Identifying Novel Gene Mutations For Molecular Diagnosis Of Familial Hemiplegic Migraine

Summary
This proposal aims to identify novel FHM genes by undertaking an NGS screen of the whole exome of 209 FHM patient samples. We will test the pathological relevance of detected novel mutations by functional analysis in human cell models and using patient-specific stem cell techniques. Using whole genome NGS technology to identify novel mutations will assist in the design and development of a comprehensive NGS approach to diagnose and differentiate this severe neurological disorder.

Nemaline myopathy is a neuromuscular condition characterised by muscle weakness, low muscle tone and the finding of nemaline bodies or rods on muscle biopsy. This study encompasses a natural history study of nemaline myopathy, genetic diagnosis and gene discovery using new methods of genetic testing, characterisation of a new disease gene for this condition, and reviewing patient experience with tyrosine, a medication commonly used in patients with nemaline myopathy.

Summary
Obesity is a worldwide concern to human health. Research into how fat is regulated in the body may provide new therapeutic options. It is not well understood how signals from the brain control fat storage. We have recently identified a gene that is important for the communication between the brain and the intestine in the control of fat levels. As such, our work will enable us to better understand this phenomenon.

Epilepsy is a serious disorder which affects approximately 2% of the population at some stage in their life and around 30% of patients do not gain adequate control of their seizures with medications presently available. Approximately 70% of epilepsy in inherited and so far the majority of the genetic causes are yet to be discovered. My group aims to identify new epilepsy genes.

Approximately 70% of epilepsy in inherited and so far the majority of the genetic causes are yet to be discovered. My group aims to identify new epilepsy genes. This leads to improved diagnosis, treatment and counseling for patients and increased understanding of the biological mechanisms underlying seizures.Read moreRead less
This study is aimed at identifying genetic variants that influence susceptibility to migraine. We plan to use DNA samples already collected from families with multiple migraine affected individuals and sequence a region on the X chromosome that has previously been identified as harbouring a migraine susceptibility gene. This project will identify gene(s) that contain variants contributing to migraine.

Summary
Frontotemporal dementia (FTD) and motor neuron disease (MND) are the two common causes of dementia and neurodegeneration. We have identified a new genes that causes familial FTD and MND in pedigrees affected with dementia and-or MND.This project will study the expression and function of this new FTD-MND gene to determine its role in the aetiology and pathology of this complex of neurodegenerative disorders.

Summary
Migraine is a frequent, debilitating and painful disorder that affects a significant proportion of the population. Using the diagnostic criteria of the international Headache Society, the prevalence of migraine has been estimated to be approximately 12%, with a recent study in the United States showing that migraine affects 4% of children, 6% of men and 18% of women. The aetiology of migraine is unknown and there are no laboratory based diagnostic tests to identify those who suffer from the diso ....Migraine is a frequent, debilitating and painful disorder that affects a significant proportion of the population. Using the diagnostic criteria of the international Headache Society, the prevalence of migraine has been estimated to be approximately 12%, with a recent study in the United States showing that migraine affects 4% of children, 6% of men and 18% of women. The aetiology of migraine is unknown and there are no laboratory based diagnostic tests to identify those who suffer from the disorder. Clinical diagnosis is currently based on patient symptom descriptions, with individual symptoms being shown to vary with age. Migraine is believed to have a genetic basis with specific environmental factors, such as particular foods, hormonal levels and fatigue, being capable of inducing attacks in predisposed individuals. Migraine shows strong familial aggregation with about 50% of those affected, having another close relative also affected with the disorder. At present the number of genes involved in the disorder is unknown and have not been identified. Recent studies in our laboratory have localised two migraine genes, one to chromosome 19 and the other to the X chromosome. More recently we have also found evidence for a third gene on chromosome 1. This study is aimed at fine scale mapping analysis of these three chromosomal regions in order to pinpoint the location of migraine genes. Our ultimate aim is to identify the molecular causes of this disorder. This would have important implications to both the diagnosis and treatment of migraine.Read moreRead less
