Systemic lupus erythematosus (SLE) is an autoimmune disease. Genetic factors account for approximately 44% of susceptibility.
How Genetic Is Lupus?
Genetics plays a meaningful role in Lupus, with heritability estimated at around 44%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Lupus: HLA-DRB1,TREX1,IRF5,STAT4. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
