HLA-E and Behcet disease: A study in Korean patients with BD indicated that the variants; HLA-E*0101 and HLA-G*010101 (p = 0.0002, OR 0.7, p = 0.002, OR 0.7, respectively) were associated with a reduced risk of developing the disease, whereas HLA-E*010302, HLA-G*010102G*0105N alleles, and 3741_3754ins14bp were all associated with an increased risk of BD (p < 0.0001, OR 1.6; p = 0.002, OR 1.8; p = 0.024, OR = 2.0; and p = 0.003, OR 1.4, respectively).
