A recent genome-wide association study (GWAS) of patients with VKH disease from a Han Chinese population identified two new non-HLA candidate regions, namely interleukin 23 receptor (IL23R)-chromosome 1 open reading frame 141 (C1orf141) on 1p31.2 and 2-aminoethanethiol dioxygenase (ADO)-zinc finger protein 365 (ZNF365)-early growth response 2 (EGR2) on 10q21.3 [17]. Here, IL23R is linked to Vogt-Koyanagi-Harada disease.
