Preparing Australia For Genomic Medicine: A Proposal By The Australian Genomics Health Alliance
Funder
National Health and Medical Research Council
Funding Amount
$25,000,000.00
Summary
The sequencing of the human genome brings the possibility of more accurate identification of the underlying basis of many diseases. This technology has moved so rapidly, however, that clinical access has been limited. In this application, a national alliance of clinicians, researchers, health economists and policymakers will evaluate the case for clinical genomics across inherited disease and cancer, determine how best to deliver this to the patient and train a capable workforce.
Neurobiology Of Childhood Speech Disorders: Improving Detection, Diagnosis And Clinical Care
Funder
National Health and Medical Research Council
Funding Amount
$994,575.00
Summary
One in 20 children have a speech disorder at school entry, with lifelong deficits in psychosocial, academic and employment outcomes. Little is known about the aetiology of speech disorders, preventing targeted care. We combine expertise in speech pathology, gene discovery and brain imaging, to advance knowledge on gene and brain contributions to speech disorder. We will have direct impacts on clinical care including detection, diagnosis and counselling, optimising outcomes for affected children.
A Functional Assay To Classify Genetic Variants In Lynch Syndrome
Funder
National Health and Medical Research Council
Funding Amount
$368,195.00
Summary
At least one person in every 1000 is affected by Lynch syndrome, in which faulty DNA repair machinery causes high rates of cancer. People with Lynch syndrome can have their risk of cancer cut substantially with regular screening. However, we often struggle to understand whether people with 'non-standard' DNA sequences in particular genes actually have Lynch syndrome. This project develops a simple test that will tell clinicians whether a given sequence change relates to Lynch syndrome or not.
Clinical Genetic Phenotyping Of Autism Spectrum Disorders
Funder
National Health and Medical Research Council
Funding Amount
$582,114.00
Summary
Individuals with autism spectrum disorders (ASD) have difficulty with communication, social interaction and intellectual disability. The cause is generally not known although most cases have a genetic basis involving multiple genes and possibly environmental factors. We will study families of children with ASD and carefully characterize features related to ASD in family members. This will help us to understand how ASD is inherited and serve as the basis for the discovery of autism genes.
Developmental genetics of malaria parasites. This project aims to improve our understanding of malarial genetics. The sexual cycle of malaria parasites occurs in mosquitoes. After sex, parasite progeny multiply to form infective spores that are injected into people by mosquito bite. Development of male and female malaria parasite gametes and their fusion to produce a diploid zygote are well understood, but the subsequent process of meiosis, development of a cyst stage and the sporogenic process ....Developmental genetics of malaria parasites. This project aims to improve our understanding of malarial genetics. The sexual cycle of malaria parasites occurs in mosquitoes. After sex, parasite progeny multiply to form infective spores that are injected into people by mosquito bite. Development of male and female malaria parasite gametes and their fusion to produce a diploid zygote are well understood, but the subsequent process of meiosis, development of a cyst stage and the sporogenic process to create haploid progeny for new infections are poorly understood in molecular genetic terms. The project aims to dissect the unique genetics of these insect stages using a rodent malaria model to generate crosses of different malaria parasite lines to determine when recombination takes effect.Read moreRead less
Genetic and molecular basis of appendicular muscle formation. Fin and limb muscles are generated in the embryo by a series of cell movements and gene regulatory events that are distinct to those that regulate the formation of the rest of the muscles of the body. This project aims to use the genetic advantages of zebrafish to determine how genes regulate fin and consequently limb muscle formation.
Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaborati ....Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaboration between a leading UK and two Australian research groups. In doing so we will provide an explanation at the molecular level for one of the great unresolved phenomena in biology: why do cold-blooded animals get bigger in the cold? The research also leads to the potential to manipulate body size in animals.Read moreRead less
Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
Endocardial sprouting and mechano-signalling in heart trabeculation. This project aims to understand how the ventricles, the pumping chambers of the mammalian heart, form during embryonic life. Critical is the elaboration of trabeculae, myocardial projections that form a sponge-like layer on the inner surface of the chamber wall and which play vital roles in contraction, oxygen and nutrient exchange, conduction and septation. The project expects to develop a deeper understanding of trabeculation ....Endocardial sprouting and mechano-signalling in heart trabeculation.

Critical is the elaboration of trabeculae, myocardial projections that form a sponge-like layer on the inner surface of the chamber wall and which play vital roles in contraction, oxygen and nutrient exchange, conduction and septation. The project expects to develop a deeper understanding of trabeculation using high resolution, single cell methodologies, and to investigate how bio-mechanical forces from contraction or blood flow influence chambers formation.Read moreRead less
Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer.

Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to generate new knowledge on the roles of natural selection in shaping the genetic variation in traits and identify key factors that drive the differentiation of human populations. These outcomes will significantly improve our understanding on the evolution of human traits and adaptation of populations to changing environments.Read moreRead less
