Scleroderma (systemic sclerosis) causes hardening and tightening of skin and connective tissue. Genetic factors explain approximately 30% of susceptibility.
How Genetic Is Scleroderma?
Genetics plays a meaningful role in Scleroderma, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Scleroderma: HLA-DRB1,IRF5,STAT4,TNIP1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
