Preventive and diagnostic testing with personalised clinical guidance
Comprehensive genomics care provided by MyGenome Australia (MGA) encompasses both preventive and diagnostic genomic testing, as relevant to each individual. Preventive genomics usually refers to genomic testing undertaken by healthy and pre-symptomatic people; whereas diagnostic genomics refers to testing for symptomatic people to identify an underlying genetic cause or a genetic diagnosis. In the real world, however, there can be overlaps between the two, in which case, a testing package with both diagnostic and preventive elements can be built, tailored to the needs of each individual. A preventive/diagnostic genome can also be analysed in the future, as one develops new health concerns as time goes, to look at relevant genes (read Patient Story on the ultimate use of genomics).
If an actionable result is found, the MGA clinicians will put in place a personalised management plan based on consensus clinical guidelines, taking into account of each individual’s personal and familial circumstances in a shared decision-making journey. Specialist referrals are arranged if needed, and personalised care plan is communicated with their GPs and other treating clinicians. Implications of a positive result for genetic relatives will also be discussed, and aids provided to help the person communicate genetic information to biological relatives. Reproductive options may also be discussed for those at an increased reproductive risk who are family planning.
Genomic testing can proactively identify actionable genetic risks of strong effect (termed ‘monogenic’ risks) for certain cardiovascular diseases, diabetes, certain cancers, and drug response to certain therapeutic medications, as well as those associated with reproductive health (section below). These genetic risks are clinically actionable, meaning that when such a risk is identified, it would lead to a change in management for the individual, which may include:
At the moment, the cumulative impact of many common genetic factors of minor effect (termed ‘polygenic’ risk), as quantified via polygenic scores (PGS), remains predominantly a research tool, as Human Genetics Society of Australasia (HGSA) Position Statement outlined that further regulatory, implementation and health system evaluations are required before PGS can be routinely implemented.
MGA is actively monitoring the readiness and appropriateness of incorporating PGS into its testing packages, and will do so when it is believed to provide useful and actionable insights into risk stratification and management.
For people with symptoms and/or family history suggesting an underlying genetic cause, diagnostic genomic testing can be arranged following clinical assessment with the MGA clinical geneticist. Any diagnostic testing arranged can be leveraged, if wished, to incorporate the preventive element, the latter to identify actionable genetic risks unrelated to their current symptoms but are predictive of their future health.
MyGenome Australia believes that precision medicine begins with understanding a person's DNA. Whether the person is planning ahead, managing existing symptoms, or exploring their family’s genetic risks, MGA's testing solutions are designed to meet each person where they are. By combining preventive and diagnostic insights, MGA aims to deliver personalised and evidence-based care that evolves with each person in a shared health journey.
