Accelerated Gene Identification Program (Gene Discovery)

Project Details

Each year almost eight million children, representing about six per cent of births worldwide, are born with a serious genetic birth defect. For more than half of these conditions, the genetic cause remains unknown. This study, which has been running since 2008, aims to understand the cause of these genetic conditions using new genetic testing technologies such as next generation DNA sequencing. This research allows us to expand our current clinical services to facilitate quicker diagnosis and more extensive genetic counselling for families with rare genetic conditions. This project encompasses a multi-disciplinary team including clinicians, researchers, biostatisticians and genetic counsellors, based at the Murdoch Childrens Research Institute, Victorian Clinical Genetics Services, Royal Children's Hospital, and the Walter & Eliza Hall Institute of Medical Research.  A specific focus is on genetic causes of brain malformations.

Collaborators

We collaborate with a range of different groups including those from the Royal Children's Hospital Melbourne, Murdoch Childrens Research Institute, University of Melbourne.  Our principle local collaborators are A/Prof Paul Lockhart, Professor Martin Delatycki and Dr Rick Leventer (Accelerated Gene Identification Program), A/Prof Melanie Bahlo (bioinformatics lead for the AGIP Program), Prof Jane Halliday (IVF studies and epidemiology), Dr David Godler (epigenetics and Fragile X), Prof Katrina Williams (Autism research), Prof Dinah Reddihough (cerebral palsy research), A/Prof Angela Morgan (Genetics of speech and language disorders).

Funding

We are funded through NHMRC and various philanthropic organisations.

Research Opportunities
