In case of KIR3DL1Low (Table 2: OR = 1.77, CI95 = 1.15; 2.73, p = 0.00954), the presence of which is negatively correlated with the presence of the KIR3DL1High (Yule’s measure of association Q=−0.997 in Controls and Q=−1 in AAA), the risk of AAA is OR = 1.9 with presence of HLA-A-Bw4 and OR = 1.7 without it. Here, HLA-A is linked to triple-A syndrome.
