HLA-B and Behcet disease: The strongest association signal was observed for rs30187 in the recessive model of the risk T allele (Arg528Lys) in HLA-B*51 carriers (P = 0.0077, OR = 2.07), which did not show any association with BD in the recessive model in the whole study population (P = 0.15, OR = 1.22).
