AMD is the leading cause of vision loss in older adults. Genetic factors account for up to 71% of risk; CFH and ARMS2 variants are the strongest known risk loci.
How Genetic Is Age-Related Macular Degeneration?
Age-Related Macular Degeneration involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 71%, though no single gene determines outcome on its own.
Key genes associated with Age-Related Macular Degeneration: CFH ARMS2 C3 C2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
