Rare Diseases Functional Genomics

The Rare Diseases Functional Genomics (RDFG) program is a joint endeavour of Kids Research, Sydney Children’s Hospital Network and Children’s Medical Research Institute. The RDFG program aims to empower the diagnosis and treatment of genetic disorders, including the rare and difficult to diagnose and to discover how genetic variants contribute to disease, with the ultimate goal of early curative treatment or disease prevention.

The RDFG program provides support to reach a molecular diagnosis of a genetic disorder by undertaking functional studies of variants of uncertain significance and triage of cases of significant clinical and scientific interest for in-depth functional genomics investigation of disease-causing mechanism to posit therapy or preclinical modelling of treatment paradigm. 

The RDFG laboratory can perform studies such as Western blotting, immunocytochemistry, mRNA analysis and cell-based assays to determine pathogenicity of variants. For genes where the functional studies are beyond the scope of the RDFG laboratory, assistance may be sought from expert researchers, or the Stem Cell & Organoid Facility and related services at CMRI.

The RDFG team is proudly supported by Luminesce Alliance, a non for profit cooperative joint venture established with the support of NSW Government to coordinate and integrate paediatric research.

The Research Team

Dr Lisa Riley, Laboratory Head

lisa.riley@health.nsw.gov.au 

Lisa is a Senior Research Officer with over 20 years of experience in functional genomics. Lisa and her team can provide advice on suitable functional assays for your gene of interest, execute the assays, and supply a research report. We also assist with preparation of publications arising from these projects.
