Genetic risk factors for rheumatoid arthritis differ in caucasian and Korean populations
AssociationN=2,131Hye‐Soon Lee et al.(2009)· Arthritis & Rheumatism

A case-control study of 1,123 Korean rheumatoid arthritis patients and 1,008 controls found that genetic variants at PTPN22, TRAF1/C5, 6q23, 4q27, CD40, and CCL21 previously associated with Caucasian RA were not associated with Korean RA. The PADI4 variant rs2240340 showed strong association (p=1.15×10⁻⁸, OR=1.43), demonstrating substantial genetic heterogeneity between ethnic populations.

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 patients
AssociationN=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]
