Infantile enterocolitis & monogenic inflammatory bowel disease
Gene: IL21Comment on list classification: One family report for IL21 variants in early onset inflammatory bowel disease, however rated green by expert and lots of evidence regarding the role of IL21 in immune responses. Orphanet: "Disease-causing germline mutation(s) (loss of function) in Autosomal recessive early-onset inflammatory bowel disease".Created: 12 Oct 2016, 3:11 p.m.
14th Oct 2016: panel revised according to expert review, additional curation for evidence level and internal clinical review, and promoted to version 1.
This gene has been classified as Amber List (Moderate Evidence).
Publications for IL21 were set to 24746753 - family report; 26681227 - evidence in rats with inflammatory bowel disease of the role of IL21; 26648777 - elevated IL21 expression in CD3+ CD8+ T cells from patients with Ulcerative colitis compared to controls; 25371082 - IL‑21KO mice were largely protected against colitis; PMID: 25162763 "IL-21 is overproduced in many chronic inflammatory disorders, including inflammatory bowel diseases, psoriasis, rheumatoid arthritis, type I diabetes and systemic lupus erythematosus, and studies in experimental models indicate that IL-21 plays an important role in sustaining tissue-damaging immune responses in such pathologies. However, genetic deficiency of IL-21 associates with inflammatory bowel diseases and blockade of IL-21 in the early phases exacerbates the disease progression in some models of rheumatoid arthritis and systemic lupus erythematosus, thus suggesting a dual role of IL-21 in the control of immune-mediated diseases."; PMID: 25037274;PMID: 24796415
