Genome-wide association tests were performed in the subgroup of GWAS discovery collections with BD uveitis and two SNPs in ERAP1 were identified to confer risk for BD uveitis recessively—rs10050860 and rs17482078, which encode p.Asp575Asn and p.Arg725Gln alterations in ERAP1 respectively (49). Here, ERAP1 is linked to Behcet disease.
