The other polymorphisms studied in MAP3K14 (rs7222094 T>C), SUMO4 (163 T>C), TNFAIP3 (rs6927172 C>G), IL1RN (rs4251961 T>C), IL4R (rs1805010 A>G), IL6 (−6331 T>C), IL17A (197G>A), IFNG (874 T>A), TGFB1 (−509 C>T) and NLRP3 (rs4612666 C>T) were not statistically associated with CD, UC or IBD in our cohort. This evidence concerns the gene IL4R and inflammatory bowel disease.
