HLA-G and Behcet disease: As expected, some of the SNPs reported to show the most significant association with BD, such as the ones in PSORS1C1, POU5F1, MUC21, HLA-B, IL23R, and HLA-G, had Fst estimates greater than their respective genes, supporting higher BD risk allele frequency difference and differentiation in these SNPs compared to other variants in their respective genes.
