To find other susceptible genes, we studied the tyrosinase gene (TYR), tyrosinase related protein 1 gene (TYRP1), tyrosinase related protein 2 gene (TYRP2), and interferon (IFN-γ), but we could not find any association with these genes and VKH disease [7,26]. The gene discussed is IFNG; the disease is Vogt-Koyanagi-Harada disease.
