Al Omar et al. also reported lack of association of KIR and colon cancer (Al Omar et al., 2010); interestingly, they showed a strong association of the presence of HLA-Bw4 (Bw4Ile80, OR = 3.1, p = 0.0001; Bw4The80, OR = 0.3, p = 0.0001 in individuals KIR3DL1+Bw4+). Here, KIR3DL1 is linked to malignant colon neoplasm.
