By analysing gene expression in CD8+ memory primary cells specifically, the strongest correlation was found with genotype at rs11955347 and expression of SLC22A5. This gene encodes a solute carrier and has previously been found to be associated with inflammatory bowel disease; however, further confirmatory work is required before association with this particular gene can be unequivocally established. The gene discussed is SLC22A5; the disease is inflammatory bowel disease.
