Development of a fast and cost effective platform for diagnosing a range of genetic disorders

HMSTrust funding enabled researchers at the Royal Children’s Hospital to develop a world-first rapid and accurate diagnostic platform, revolutionising the way genetic disorders are diagnosed.

Snapshot:

Up to 5% of children are born with genetic disorders which can have a significant, lifelong impact on the affected individuals and their families. It can take years for a disorder to be diagnosed and allow for properly informed clinical management.

Using Disorders of Sex Development (DSD) as the paradigm for all other genetic disorders, the researchers set out to develop a diagnostic platform for children with DSD by combining state-of-the art Next Generation sequencing with a new technique they had developed to screen DNA.

The outcomes of the project significantly exceeded expectations:

  • Development of a powerful and cost-effective new tool to rapidly identify the disease-causing variant in genes, leading to improved clinical management and outcomes.
  • Proof that this targeted gene panel is cost effective, efficient, rapid and accurate provides the opportunity to develop similar diagnostic tests for other difficult childhood conditions.
  • The project’s success leveraged further funding of $8m from government and philanthropy and has positioned The Royal Children’s Hospital as a global leader for diagnosis of DSD patients.
  • Prior to the project, 70% of DSD patients went undiagnosed. Using the new method, a majority of children now receive a diagnosis.
  • By providing a rapid, clear definitive diagnosis, the child and their families are spared many invasive investigative procedures that can be both prolonged and expensive, saving money for both families and the Government health budget.
  • The method has been transitioned into the Victorian Clinical Genetics Service as a fully accredited clinical diagnostic test.
  • The high diagnostic success rates will be used as part of a health economic case being put to the Federal Government to place a Medicare rebate on rapid, powerful, cost-saving diagnostic tests such as this.
