Recently, a common insertion/deletion (-94 insertion/deletionATTG rs28362491) polymorphism in the NFκB1 promoter region and a 3′ -untranslated region (3′UTR) polymorphism 2758A>G (rs696) in NFκBIA were observed to be significantly correlated with inflammatory bowel disease [31], [32] and cancers [33], [34], [35]. Here, NFKBIA is linked to cancer.
