Multisystem granulomatous disease with moderate genetic component. Susceptibility varies strongly by ancestry and HLA type.
How Genetic Is Sarcoidosis?
Sarcoidosis involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 36%, though no single gene determines outcome on its own.
Key genes associated with Sarcoidosis: HLA-DRB1 BTNL2 ANXA11. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Sarcoidosis?
Family history can be informative for Sarcoidosis, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
