The Collaborative AuTism Study (CATS)
The Collaborative AuTism Study (CATS) originated in the Geelong region over 10 years ago due to the efforts of Associate Professor Peter Hewson, a local paediatrician who ascertained that autism was one of the most challenging disorders that a paediatrician faced. He saw a need to study and understand Autism Spectrum Disorder (ASD). Starting with a regional database of patients with ASD, A/Prof Hewson sought a collaboration with Professor Ingrid Scheffer, paediatric neurologist, and Professor Martin Delatycki, clinical geneticist. Together they established the CATS team, and sought to measure the prevalence of ASD in the region, and to identify its genetic causes.
Today, our multidisciplinary team is working on gene discovery for various medical disorders, with expertise in clinical, molecular, bionformatics, and basic science domains. In collaboration with molecular scientists, Professor Scheffer discovered the first gene for epilepsy and many epilepsy genes since. Using the new genetic technologies, and working with molecular scientists, she has led the discovery of several genes for ASD and intellectual disability. Together, the CATS team bring their combined expertise to the challenge of finding genetic causes of ASD and understanding their inheritance.
To identify genetic causes of ASD and other risk factors, our team studies individuals with ASD and their families using cutting-edge research methods and technologies.
