Neurogenetics Group

The Neurogenetics Group is interested in learning more about major genetic neurological disorders as a way of understanding the neurobiology of human brain function. 

Identifying the genes and their mutations implicated in major neurological disorders—like intellectual disability, autism, epilepsy and cerebral palsy—represents a challenge of significant medical importance. However, it is by understanding the molecular mechanisms of these genetic mutations that the role of specific genes and proteins in normal brain function can be discovered. 

Our group has made great leaps in this field. We identified the first gene for non-syndromic intellectual disability (ID): the most frequently mutated gene in mild to borderline ID. We have also discovered, or contributed to the discovery of, more than 100 different genes in new and unexpected biological pathways essential for normal brain function—such as non-sense mediated mRNA decay.  

The Neurogenetics Group is also interested in non-coding DNA regulatory mutations causing ID. We discovered a gene mutation in a large Australian family with non-syndromic ID that had eluded scientists and clinicians for over 40 years. ID was initially regarded as a slightly separate field to epilepsy genetics. Our gene discoveries in ID point to an increasing overlap between ID and epilepsy, which may explain their frequent co-occurrence. 

Our key research strengths are:

  • genomics and bioinformatics
  • molecular mechanisms of intellectual disability 
  • molecular neuroscience 
  • animal models.

Our research is complemented by many national, international clinical and basic science collaborators.
