Genomic screening uncovers hidden health risks for patients

A recent study has shown that genomic screening can uncover hidden health risks for patients. This research was part of Geisinger’s MyCode Community Health Initiative, which analyzes genetic information to inform participants about their risk of diseases. In the study, published in JAMA Network Open, over 175,000 participants were screened. About 1 in 30 received significant genetic findings. More than 90 percent of those with a genetic risk were not aware of their risks before joining the program. Currently, clinical genetic testing often depends on a patient’s personal or family medical history. This can miss many individuals who may be at risk but do not have a family history or do not access care due to various barriers. Genomic screening can help identify more at-risk patients. To date, over 354,000 people have taken part in the MyCode initiative, which focuses on how genetics influence health and diseases, including cancer and heart conditions. Early detection can lead to better treatment outcomes. Geisinger’s initiative is notable because it is one of the first healthcare systems to provide participants with actionable genetic results. Christa Martin, chief scientific officer at Geisinger, highlighted that sharing these results promotes preventive care and targeted treatments.
