An Australia-first service that combines whole genome sequencing and a comprehensive health assessment could offer individuals an unprecedented glimpse into their future health.

People with a niggling curiosity and $6400 can now find out if their genetics and lifestyle has left them prone to developing a suite of life-threatening conditions including 31 types of cancer and 13 heart conditions across 230 genes.

Launched on Tuesday by Sydney's Garvan Institute's Genome.One lab and corporate clinic Life First, the service also offers individuals the ability to predict how they would likely react to more than 220 medications, allowing clinicians to better tailor treatment to their patients.

CEO of Genome.One Dr Marcel Dinger said the service marked the start of a new era in precision medicine that balanced an individual's genetic predisposition to disease with lifestyle factors.
