Intellectual Disability Research Laboratory
Identification of genes and understanding of molecular mechanisms leading to intellectual disabilities, autisms and some epilepsies represents a challenge of significant medical importance. Our research seeks to further our understanding of human brain function through the identification of genes and characterisation of their naturally occurring mutations implicated in various disorders of the brain.
Led by A/Prof Cheryl Shoubridge, the Intellectual Disability Research laboratory focuses on identifying the molecular mechanisms and functional impact of mutations in genes causing X-linked intellectual disability (XLID). This research team is currently funded by two NHMRC project grants and a ARC Future Fellowship.
The key areas of research include:
- Utilize primary neuronal cell culture models to investigate the functional impact of patient mutations in genes involved in X-linked Intellectual disability, in particular the ARX and IQSEC2 genes.
- Animal models to investigate functional impact of the two most frequent expanded polyalanine tract mutations in the ARX gene.
- Establish the molecular mechanisms of disease associated with a range of expanded polyalanine tract mutations in ARX to begin to understand how these mutations underpin the intellectual disability with and without a broad spectrum of associated clinical symptoms in affected patients, including epilepsy.
- Investigate how phosphorylation may regulate the function of the ARX homeodomain transcription factor.
- Screen ARX and IQSEC2 in various patient and control groups.
Available research Projects for Honours and HDRs
Title: Towards treating IQSEC2 associated intellectual disability, autism and epilepsy
Description:Drugs and treatments targeting the molecular pathophysiology induced by a genetic cause will be validated using primary hippocampal neuronal cultures in conjunction with a CRISPR generated KO mouse modelling human mutations which recapitulate the ID, social behavioral abnormalities and epilepsy seen in human patients. We focus on the geneIQSEC2which has been associated these disorders in male and increasingly in female children.
Projects available for: Honours and HDR
Research project start:Semester 1 or 2
Title:Mechanisms of 17B-estradiol treatment improving intellectual disability and seizures
Description:The current project seeks to characterize and understand the drivers underpinning phenotypic improvements following a postnatal treatment strategy in a genetic mouse model of intellectual disability and seizures. This project focuses on the two most frequent expanded polyalanine tract mutations in the ARX gene. The key approaches will investigate animal models including seizure monitoring and behavioral analysis, through to RNASeq to examine transcriptome wide changes and associated changes to interneuron populations in the developing brain.
