How Genetic Is Behcet Disease?
Behcet Disease involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 40%, though no single gene determines outcome on its own.
Key genes associated with Behcet Disease: HLA-B51 IL10 IL23R. 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 Behcet Disease?
Family history can be informative for Behcet Disease, 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.
