Summary
This project will use a new stem cell model to discover what happens to brain cells in patients with the MELAS 3243A>G mutation, a common genetic mutation found in 1-500 Australians. Brain cells will be grown from our stem cell model and used to find out how this mutation causes problems in the affected brain cells. We will find out what happens to the brain when the amount of mutation is reduced in vitro. By understanding what happens, we will be able to design new treatments for this disord ....This project will use a new stem cell model to discover what happens to brain cells in patients with the MELAS 3243A>G mutation, a common genetic mutation found in 1-500 Australians.

Transforming The Diagnosis Of Mitochondrial Disorders Using High-throughput Sequencing, Functional Prediction And Experimental Validation

Funding Amount
$670,794.00
Summary
The human genome project sparked enormous improvements in our ability to sequence DNA. “Next Generation” DNA sequencing can potentially sequence an individual’s entire genome in a week and has the ability to transform the diagnosis of inherited diseases but is as yet unproven in a medical genetics context. We will develop and validate the use of Next Generation sequencing to enable the rapid sequencing of over 1000 genes in which mutations cause inherited metabolic diseases.
I work on mitochondrial diseases, which are inherited disorders of metabolism that block conversion of food energy into chemical energy needed by our cells. We focus on understanding (i) the genetic basis of these disorders using approaches such as massively parallel sequencing, systems biology and experimental studies, and (ii) the detailed mechanisms of disease by studying cell lines from patients and animal models. We aim to develop better methods for diagnosis, treatment and prevention.
Identifying Mitochondrial Genome Variants Associated With Familial Migraine Susceptibility

Funding Amount
$443,273.00
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.
