This important SNP, located in the PTPN22 gene and also known as R620W, C1858T, or 1858C>T, may influence risk for multiple autoimmune diseases, such as Rheumatoid Arthritis, Type-1 diabetes, Autoimmune thyroiditis, and Systemic lupus erythematosus.


[PMID 25003765OA-icon.png] PTPN22: the archetypal non-HLA autoimmunity gene. A 2014 article explained that "PTPN22 exemplifies a shared autoimmunity gene, affecting the pathogenesis of systemic lupus erythematosus, vasculitis and other autoimmune diseases." They explored "the role of PTPN22 in autoimmune connective tissue disease" and theorized "a number of PTPN22-dependent functional models of the pathogenesis of autoimmune diseases." (Abstract). They explained that "the PTPN22 gene is a major risk factor for autoimmunity." As well, "In addition to autoimmune diseases, PTPN22 1858C>T also affects susceptibility to infectious diseases."

[PMID 15719322OA-icon.png] A 2005 study titled "Analysis of families in the multiple autoimmune disease genetics consortium (MADGC) collection: the PTPN22 620W allele associates with multiple autoimmune phenotypes" stated "We report that a recently described functional single-nucleotide polymorphism (rs2476601, encoding R620W) in the intracellular tyrosine phosphatase (PTPN22) confers risk of four separate autoimmune phenotypes in these families: T1D, RA, SLE, and Hashimoto's thyroiditis. MS did not show association with the PTPN22 risk allele. These findings suggest a common underlying etiologic pathway for some, but not all, autoimmune disorders, and they suggest that MS may have a pathogenesis that is distinct from RA, SLE, and T1D." (Abstract).

Promethease reports for rs2476601 from Trait-o-matic are consistently finding this called as (A;G), while microarray results seem to follow the HapMap predictions. The source of this originates upstream in several different genotype callers:

  • maq
  • SoapSNP
  • AB_SOLiD_SNP_caller
  • JW
  • NA18507
  • SIQ2
  • CV

This is probably triggered by the oddness of this dbSNP entry in which it is a C=>T in NM_012411.2 and a T=>C in NM_015967.3 and/or the fact NT_019273.18 was replaced by NT_032977

Rheumatoid arthritis[edit]

[PMID 17554300OA-icon.png] A 2007 study titled "Genome-wide association study of 14,000 cases of seven common diseases and 3,000 shared controls" examined approximately 2,000 individuals for each of 7 major diseases and a shared set of approximately 3,000 controls in the British population. They found that in the case of rs2476601, the risk was consistent with previous estimates for RA, approximately OD 1.8, and that "known associations with HLA-DRB1 and PTPN22 explain around 50% of the familial aggregation of RA." They found a correlated marker for RA, rs6679677. In addition, SNP rs11761231 had no effect on risk in males, but in females had an "additive OR for females 1.32"

[PMID 16175503OA-icon.png] A 2005 study titled "PTPN22 genetic variation: evidence for multiple variants associated with rheumatoid arthritis" found that R620W rs2476601 polymorphism was the most significant SNP in sample set of 37 SNPs. They also found these significant ORs for RA (estimated for the minor allele of each SNP; Table 1):

However, they found that "R620W by itself does not account for all the association observed between RA and PTPN22 in both sample sets." Further analysis revealed that two of the SNPs were important in relation to rs2476601, namely their SNP "number 27" (rs1310182) and "number 37" (rs3789604, which had OR 1.39 (p=0.0071). It showed that the R620W polymorphism was moderated by other SNPs, one increasing its OR, the other decreasing it..

  • In combination, the minor allele of rs3789604 gave an increased OR of 2.53 to minor allele homozygotes and 1.77 to heterozygotes of rs2476601
  • In combination, the minor allele of rs1310182 gave a decreased OR of 1.63 to minor allele homozygotes and 1.34 to heterozygotes of rs2476601

[PMID 15934099] A 2005 study titled "Association between the PTPN22 gene and rheumatoid arthritis and juvenile idiopathic arthritis in a UK population: further support that PTPN22 is an autoimmunity gene" found that "There was a significant association between the PTPN22 SNP and RA (P = 1.8 x 10(-8)) and JIA (P = 0.0005). In contrast, no association with psoriasis, PsA, or MS was detected." (Abstract).
