SLC22A4 and inflammatory bowel disease: Interestingly, given that single nucleotide polymorphisms (SNPs) located near or within m6A motifs have been proposed as possible contributors to disease, a recent study identified five candidate genes corresponding to two of the major IBD subtypes: ubiquitin-conjugating enzyme E2L3 (UBE2L3) and solute carrier family 22 member 4 (SLC22A4) for Crohn’s disease and transcription factor 19 (TCF19), chromosome 6 open reading frame 47 (C6orf47), and small nuclear RNA-activating complex polypeptide 4 (SNAPC4) for ulcerative colitis [64].
