How Are Minor Genetic Variations Studied in Epidemiology?
Researchers use various methods to study minor genetic variations, including genome-wide association studies (GWAS) and candidate gene studies. GWAS involve scanning the entire genome of many individuals to identify genetic markers associated with specific diseases. Candidate gene studies, on the other hand, focus on examining specific genes that are thought to be related to a disease based on existing knowledge. Both approaches help in identifying genetic factors that contribute to disease risk and progression.
