Summary
Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function. When NMD is compromised the outcome is learning and memory problems, autism or schizophrenia. Under this project we study malfunctioning NMD using stem and neuronal cells derived from patients' skin cells. Some of the affected genes might be considered for therapeutic interventions. NMD is relevant to 1000s of human disorders and as such it is of fundam ....Proper functioning of the nonsense mediated mRNA decay (NMD or 'mRNA police') is crucial for any cell to ensure normal development and function.

$880,569.00
Summary
Inherited muscle disorders lead to lifelong disability and early death. Less that 50% of patients get an accurate diagnosis and there are currently no effective therapies. In this project, two leading Australian laboratories will use state-of-the-art methods to identify novel disease genes and how they cause muscle weakness. This research will have immediate outcomes to diagnosis, management and prevention and for the development of new therapeutic agents.
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.
In Vivo Analysis Of The Molecular And Neural Mechanism That Underly An Association Of MiRNAs With Mental Disorders

Summary
Genetic studies on autism, schizophrenia, bipolar disorder and major depression suggest that these disorders affect the formation and maintenance of connections between neurons. A group of brain-specific microRNAs, which are regulatory molecules, are predicted to regulate connectivity. Levels of these molecules are found to be abnormal in brains of patients with schizophrenia. This proposal aims to elucidate the function of these microRNAs in the number of neuronal connections, and early motor b ....Genetic studies on autism, schizophrenia, bipolar disorder and major depression suggest that these disorders affect the formation and maintenance of connections between neurons. A group of brain-specific microRNAs, which are regulatory molecules, are predicted to regulate connectivity. Levels of these molecules are found to be abnormal in brains of patients with schizophrenia. This proposal aims to elucidate the function of these microRNAs in the number of neuronal connections, and early motor behavior in transgenic zebrafish.Read moreRead less
The Effects Of ?-actinin-3 On Muscle Metabolism, Human Health And Disease

Summary
We have identified a common genetic variant that results in absence of the fast muscle fibre protein ?-actinin-3 in more than one billion humans worldwide. Loss of ?-actinin-3 influences elite athletic performance, muscle bulk and strength in the general population, response to diet and exercise, and susceptibility to obesity and developing type 2 diabetes. We have also demonstrated that ?-actinin-3 influence disease severity in a variety of inherited and acquired muscle disorders.
Developing Bone Marrow Transplant And Novel Therapeutic Vectors To Treat Friedreich Ataxia

Funding Amount

Summary
We aim to develop effective therapies for the neuromuscular disease Friedreich ataxia (FRDA). The neurodegeneration inherent to FRDA slowly robs a person of the ability to move freely and care for themselves. It needs life-long medical support and there is no cure. FRDA lowers frataxin, a critical mitochondrial protein. Evidence indicates increasing frataxin can be beneficial. Using disease models, we will determine if increasing frataxin via bone marrow transplant or gene therapy improves FRDA.
Haplotype Variation At The Dopamine Transporter Gene (SLC6A3): Effects On Function, Endo-phenotypes, Cognition And ADHD

Funding Amount

Summary
We will investigate variation in the dopamine transporter gene. Variation in this gene will be characterised to a deeper level than has been previously possible using the latest sequencing technology, its biological function will be investigated using biochemical and neuroimaging methods directly in human subjects, and its effects on a clinically important cognitive measure and a common psychiatric condition (attention deficit/hyperactive disorder) will we determined.
