DNA and RNA Methodologies

The focus of the DNA and RNA Methodologies Group is the development and application of innovative methods and novel approaches to overcome current scientific limitations. Early work created two research-validated diagnostics for cancer-associated fusion genes using hybridisation capture sequencing (targeted RNAseq), with the same technology applied to conventional chromatin sequencing to enhance epigenetic studies (ChIP-CapSeq).

As fusion genes drive 20% of all cancer incidence, we initially focused on realising the clinical potential of our fusion gene tests to accurately diagnose fusions in cancer patients, surpassing conventional testing methods such as FISH and qRT-PCR. Given our technical expertise, the group’s research portfolio expanded to include sequencing for the Molecular Screening and Therapeutics (MoST) program of Omico Australia, with the objective of translating genomic screening into health outcomes for Australian cancer patients with advanced or metastatic disease and an unmet clinical need.

In line with our current projects, we are additionally developing new methodologies to improve next-generation sequencing library preparation for formalin-fixed and degraded tissues. These enhancements also have the potential to be deployed in a clinical context to improve patient sample sequencing eligibility and success.
