Public Health Genetics

Public Health Genetics is the application of genetic knowledge and technologies to improve population health and prevent disease at the community and societal levels. It integrates genetics with public health principles to identify genetic risk factors, understand gene–environment interactions, and develop preventive strategies for common and inherited conditions. Public health genetics supports programs such as newborn screening, carrier screening, population-based genetic testing, and risk assessment for diseases like cancer, cardiovascular disorders, and metabolic conditions. A key focus is translating genetic discoveries into equitable, evidence-based interventions that benefit entire populations, not just individuals. Ethical, legal, and social considerations—such as informed consent, privacy, nondiscrimination, and access—are central to practice. By combining surveillance, education, policy development, and preventive care, public health genetics advances precision prevention, reduces disease burden, and promotes healthier populations while ensuring responsible use of genetic information.
