Figure 1. The distribution of killer cell immunoglobulin-like receptor (KIR) gene frequencies in Saudi patients with Vogt-Koyanagi-Harada (VKH) disease and in control subjects. The frequency of each gene is expressed as a percentage and is defined as the number of individuals possessing the genotype (N+), divided by the total number of individuals studied (n). *KIR2DS3 is significantly higher in the VKH patients compared to the controls. The KIR data for the Saudi controls was obtained from our previous publication [28]. The framework genes (KIR3DL2, 3DL3, 2DL4, and 3DP1) were invariably present in all individuals.
