Coeliac disease is an autoimmune reaction to gluten strongly associated with HLA gene variants. First-degree relatives of affected individuals have a 10% risk.
How Genetic Is Coeliac Disease?
Genetics plays a meaningful role in Coeliac Disease, with heritability estimated at around 70%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Coeliac Disease: HLA-DQ2,HLA-DQ8. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
