▶A PTPN22 promoter polymorphism −1123G>C is associated with RA pathogenesis in ChineseAssociationN=990Jian-Jun Huang et al.(2012)· Rheumatology International
In Chinese Han populations, the PTPN22 promoter polymorphism -1123G>C (rs2488457) is associated with rheumatoid arthritis susceptibility with OR=1.517 (95% CI 1.154-1.995, P=0.003). The well-documented exon 14 variant 1858C>T (rs2476601) and the 788G>A variant (rs33996649) were not polymorphic in this Chinese cohort, suggesting population-specific genetic risk variants for RA.
▶The protein tyrosine phosphatase N22 gene is associated with juvenile and adult idiopathic inflammatory myopathy independent of the HLA 8.1 haplotype in British Caucasian patientsAssociationN=1,129Chinoy H. et al.(2008)· Arthritis & Rheumatism
Case-control study of 381 UK Caucasian idiopathic inflammatory myopathy (IIM) patients and 748 controls examining PTPN22 SNPs. The R620W variant (rs2476601) showed significant association with overall IIM (OR=1.8, p=0.00007) and particularly with polymyositis (OR=2.2, p=0.0001) and juvenile dermatomyositis (OR=2.1, p=0.0006). The association was independent of the HLA 8.1 haplotype.
About PTPN22
This gene encodes of member of the non-receptor class 4 subfamily of the protein-tyrosine phosphatase family. The encoded protein is a lymphoid-specific intracellular phosphatase that associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. Mutations in this gene may be associated with a range of autoimmune disorders including Type 1 Diabetes, rheumatoid arthritis, systemic lupus erythematosus and Graves' disease. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Mar 2009]
