Summary
Around 2% of people have epilepsy at some time in their lives. A large proportion of cases are thought to have a genetic cause, but genes have not yet been identified for most patients. The aim of this project is to use state-of-the-art genetic methods to identify genetic mutations causing epilepsy and to then study the effects of these mutations to better understand the biological causes of epilepsy. This in turn will lead to better diagnosis of epilepsy and improved treatment for patients.
Identification And Characterisation Of Genes Causing Autosomal Dominant Nocturnal Frontal Lobe Epilepsy (ADNFLE) And Related Phenotypes

Summary
Epilepsy affects approximately 2% of the population at some stage of their lives. We have recently identified two new genes involved in the development of a type of epilepsy known as ADNFLE. We aim to identify further epilepsy genes by sequencing ADNFLE patients who do not yet have identified mutations. We also aim to identify the genes interacting with the genes we have identified, increasing our understanding of the cellular networks involved in the development of epilepsy.
Novel Gene Identification And Characterisation In Epilepsy.

Funding Amount
$303,964.00
Summary
Epilepsy is a serious neurological disorder affecting up to 5% of the population at some point in their lives. Approximately 70% cases of epilepsy are genetic, but very few of the genes involved have been identified. This project will use state-of-the-art techniques to identify genetic mutations causing an inherited form epilepsy affecting infants. This research is expected to reveal new gene families involved in the genesis of epilepsy and thus new targets for the development of treatments.

Summary
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.

Investigating The Pathogenic Mechanism Of Mutations In IQSEC2 Causing Non-syndromic Intellectual Disability.

Funding Amount
$449,016.00
Summary
Intellectual disability is frequent in the population, as many as 1 in every 50 people in the world affected. Mutations in IQSEC2, an X-chromosome gene, cause intellectual disability. We will screen 1000 families with this disability for mutations in IQSEC2, building the picture of disease symptoms, contributing to informed genetic counselling. We will investigate functional impacts of these mutations in neuronal cultures, increasing our understanding of the causes of intellectual disability.
Identification Of Genes For X-linked Mental Retardation.

Funding Amount
$675,228.00
Summary
We propose to identify novel heritable causes of intellectual disability using 22 large and well-characterised families from Australia. In these families we have refined the location of the genetic defect to the chromosome X and excluded the contribution of all so far known genes. We will achieve this using the technology of massive parallel sequencing. At the completion of the project we will have identified novel causes of intellectual disability and devised tests to identify them.

Summary
There are fourteen human genetic diseases that are caused by a similar mutation mechanism and have similar clinical outcomes - the loss of function, degeneration and eventual death of nerve cells. This group of diseases includes Huntington's Disease. They are transmitted from parent to offspring such that each child of an affected parent has 50% risk of inheriting the affected gene and therefore developing the disease. The symptoms of these diseases typically develop later in life - between the ....There are fourteen human genetic diseases that are caused by a similar mutation mechanism and have similar clinical outcomes - the loss of function, degeneration and eventual death of nerve cells. This group of diseases includes Huntington's Disease. They are transmitted from parent to offspring such that each child of an affected parent has 50% risk of inheriting the affected gene and therefore developing the disease. The symptoms of these diseases typically develop later in life - between the ages of 35 and 50 years. While the different genes for these diseases have been identified the pathways that lead from their similar form of mutation to their similar clinical outcomes are not yet understood. Some evidence suggests that certain of these diseases have a common toxic component but this component is not shared by all of the disease genes and so an additional agent that they have in common is being sought. This research will use a genetic model organism - the vinegar fly, Drosophila melanogaster, to test the identity of a good candidate (RNA) for a common toxic agent and to provide information about the pathway by which RNA leads to nerve cell degeneration and death. Accurate and complete knowledge of the identity and composition of the pathways that lead from the mutation to the disease are crucial for correct target identification in the development of drug leads.Read moreRead less
