Vitiligo is an autoimmune skin disorder causing loss of skin pigmentation. Genetic factors explain approximately 46% of susceptibility.
How Genetic Is Vitiligo?
Genetics plays a meaningful role in Vitiligo, with heritability estimated at around 46%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Vitiligo: NLRP1,PTPN22,TYR,HLA. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
