Epilepsy is the name of a group of disorders where seizures occur. 5% of people will have at least one seizure. Seizures accompanied by fever (febrile) are common in early childhood. Most forms of epilepsy and febrile seizures have an inherited component. Progress in finding genes for common forms of epilepsy has been slow, probably because they are due to the interaction of a number of genes. Four genes for rare epilepsies with single gene inheritance have been identified. These genes code for ....Epilepsy is the name of a group of disorders where seizures occur. 5% of people will have at least one seizure. Seizures accompanied by fever (febrile) are common in early childhood. Most forms of epilepsy and febrile seizures have an inherited component. Progress in finding genes for common forms of epilepsy has been slow, probably because they are due to the interaction of a number of genes. Four genes for rare epilepsies with single gene inheritance have been identified. These genes code for subunits of ion channels in cells. We study families where many individuals have seizures and carefully diagnose the seizures types. This work has resulted in the description of 5 new inherited epilepsies and led to discovery of 3 of the 4 known genes. The most important new inherited epilepsy is Generalized Epilepsy with Febrile Seizures Plus (GEFS+). GEFS+ accounts for many children with febrile seizures restricted to early childhood, or where seizures continue into mid-childhood. GEFS+ families may contain an individual with severe generalized epilepsy with intellectual disability. In a Tasmanian family with GEFS+, we found a gene defect in the sodium channel of nerve cells in the brain. We plan to study more families with GEFS+. We believe that specific severe childhood epilepsies may occur in families with GEFS+. If so, then the underlying cause of these serious disorders may be gene defects of GEFS+. Finding such genes will help to understand the basis of seizures and ultimately lead to targeted therapies. The second major focus of our work on GEFS+ is to use family studies to understand how different types of seizures are inherited, and to gain insights into the gene interactions underlying common epilepsies. We plan to study isolated cases of GEFS+ for the gene defects found in families. This strategy will reveal whether the same genes are important in the genetics of the common epilepsies.Read moreRead less
Mechanisms Underlying Generation Of Febrile Seizures In Mouse Models Of Human Familial Epilepsy

Summary
Febrile Seizures (FS) affect 3% of children aged 0.5 - 6 yrs and have been proposed as an indicator of severe forms of adult generalized epilepsy. Mechanisms underlying FS generation are unknown although studies of Australian families suffering from epilepsy have linked 2 genes to FS. We have generated mice expressing these 2 genes. Aims and Outcomes: to investigate events triggering FS which will provide important insights into why FS occurs in children. (NB: CIA 2 yr career interruption)
Epilepsy is a common disease in the Australian population affecting 3 percent of individuals. It incurs lifelong medical, social and educational costs, and in some cases can be fatal. It is a large burden on public healthcare in Australia. Focal epilepsies are the most common type of seizure that arise from specific parts of the brain. This study has two aims and a future strategy relevant to gene discovery and clinical testing for focal epilepsy.

Epilepsy is a common disease in the Australian population affecting 3% of individuals that has a significant genetic contribution. To improve patient care we will study a unique set of identical twins discordant for different types of common genetic epilepsies. Identification of novel genes involved in common epilepsies will provide information relevant to prognosis, recurrence risks and treatment options for patients and their families.

Responsive Endovascular Neuromodulation: Detection And Suppression Of Epileptic Seizures

Summary
For millions of people with epilepsy, seizures can be debilitating and dangerous. Medical devices approved for seizure prevention require risky open-brain surgery and traumatic electrode insertion. The Stentrode can record and stimulate the brain from within a blood vessel. By optimising it for delivery into small vessels, designing software to detect seizures, and conducting chronic safety studies, I will create a tool that can detect and suppress epileptic seizures without the surgical risk.
I aim to understand the genetics of the epilepsies. Through detailed analysis of different types of epilepsy, and associated features such as intellectual disability and autism, I will describe new epilepsy syndromes, and together with gene discovery, implement novel targeted therapies. This translational program will transform clinical practice by informing diagnosis, prognostic and genetic counseling, and lead to targeted precision therapies to improve outcomes for each patient.

Summary
Finding genetic causes of epilepsies is vital for accurate diagnosis and family counseling, to optimize current treatments and to develop novel therapies. We will leverage our large collection of carefully evaluated Australian cases with international data sets, coordinated by Consortia that I chair, to develop a detailed understanding of the genetic causes of epilepsy. This will transform the use of genetics in the clinic, lead to better immediate treatment and aid in developing novel therapies
