PGS is the large-scale testing of individuals in a population to identify genetic variants that may indicate a risk for to certain diseases, allowing for early interventions and personalized healthcare.
How is PGS different from traditional genetic testing?
Traditional genetic testing is usually performed based on a person’s medical history or symptoms, whereas PGS proactively screens large groups of people, regardless of their health status, to assess genetic risks.
Who can benefit from PGS?
PGS can benefit everyone by identifying potential genetic risks for conditions such as cancer, cardiovascular diseases, and inherited disorders, enabling early detection and preventive measures.
How accurate is genomic screening?
PGS is highly accurate in detecting known genetic variants; however, results may not always predict disease development with certainty. Environmental and lifestyle factors also play a role in disease risk.
Will PGS tell me if I will definitely develop a disease?
No, PGS identifies genetic predispositions, meaning you may have a higher or lower risk for certain conditions, but it does not guarantee disease development.
Can PGS detect all genetic conditions?
No, PGS is limited to screening for specific conditions and known genetic variants. It does not detect all genetic disorders or predict all health risks.
Will my genomic data be kept private?
Most PGS programs follow strict privacy regulations to protect genetic data. It’s important to review the privacy policies of the screening provider.
Can my genetic data be used by insurance companies or employers?
Laws such as the Genetic Information Nondiscrimination Act (GINA) in the U.S. prohibit genetic discrimination in health insurance and employment. However, policies may vary by country.
What happens to my data after screening?
Data handling depends on the provider’s policies. Some programs store data for research, while others allow participants to control how their data is used.
What should I do if I have a high genetic risk for a condition?
Talk with your doctor, genetic counselor or other healthcare provider to understand your results and discuss preventive measures, lifestyle changes, or further medical testing.
How often should I get genomic screening?
Since genetic makeup does not change, screening is typically a one-time test. But, changes in what we know about genetics over time could lead to updates in the medical importance of your genetic makeup.
