Peter Mac has designed a Molecular Genomics Diagnostic Reporting Package (PathOS) that uses cutting edge bioinformatics tools, federation of databases and a clinical information exchange platform to provide the clinician with a comprehensive account of the patient’s genomic landscape, a list of “actionable” mutations (e.g. mutations that can be specifically targeted using so-called designer drugs).
PathOS is a unique, in-house automated software solution that provides clinical decision support tools for understanding genetic mutations. PathOS enables bioinformatics filtering, classification of variants, annotation, curation and clinical reporting all in a ISO15189 accredited framework.
Sequencing is now delivered as turnkey hardware and is rapidly becoming commoditised, but pipelines and curation rely on software and global databases that are still immature. Peter Mac is at the forefront of interpretation via the development of PathOS and associated skills and expertise in bioinformatics.
PathOS integrates a patient’s genetic data and cancer type with global databases to provide clinicians with reports to match patients with optimal treatments. It is also used in clinical trials to improve patient care and evaluate new therapies.
NEXT GENERATION SEQUENCING
PathOS reports on two key parts of next generation sequencing:
- data quality review – PathOS report on key data quality metrics arising from the sequencing output enabling an accurate review of the test data
- clinical report – reports on the mutations with actionable treatment outcomes and highlights any applicable clinical trials. Peter Mac’s experts ensure that PathOS data is up-to-date with the latest in clinical treatment and trials
The PathOS data base size is 8.8m variants with 3,900 curated variants from 119,000 sequenced samples. Peter Mac has in-house capabilities to review and curate any unknown variants to decipher whether they are pathogenic and have actionable treatment outcomes. A cloud instance has been set up here for demonstration. Access can be arranged through the project contact.
Peter Mac is interested in collaborating to expand and develop PathOS.
The development of PathOS is also targeted at institutions beyond Peter Mac that perform high throughput clinical sequencing. To make the capabilities of PathOS available to other groups and extend the features of PathOS, a number of collaborations have begun with the Children’s Cancer Institute, the Murdoch Children Research Institute, the Garvan Institute of Medical Research, the Melbourne Genomics Health Alliance and the Australian Genomics Health Alliance.
