ptpn22 rheumatoid arthritis
The tyrosine phosphatase PTPN22 allele 1858T has been associated with rheumatoid arthritis (RA) and other autoimmune diseases. PTPN22 splice forms and rheumatoid arthritis Alternative splicing is a process whereby distinct mRNA transcripts are generated from a single gene so that the resulting splice variants can be translated into different protein isoforms. During this process, a particular exon can be connected to any of the other exons to form a mature mRNA. No evidence for association with RA was identified for any of the *PADI4* SNPs investigated. Studies Research Journal of Medical Sciences and Metagenomics. Three SNPs (rs2476601-rs12730735-rs11102685) were selected for which we estimated the genotypic relative risks (GRRs) of the corresponding genotypes.

Steer S, Lad B, Grumley JA, Kingsley GH, Fisher SA. Whilst RA can happen to anyone, people with other autoimmune diseases, including type 1 diabetes , in the family have a higher chance of developing the condition. The main issue in studying citrullinated proteins related to RA is that there could be a wide variety of citrullinated proteins present in the inflamed synovium and surrounding tissue. PTPN22 encodes a lymphoid-specific tyrosine phosphatase (LYP) that is a master regulator of the immune response. A single nucleotide polymorphism (SNP) in the PTPN22 gene has recently been shown to associate with rheumatoid arthritis (RA) with a strength of association second only to that of the HLA region encoding the MHC class II shared epitope (SE).

The genetic factors include single-nucleotide polymorphisms (SNPs), which have been reported to be associated with RA, but their specific role in the pathogenesis of RA remains unexplained. The PTPN22 association with rheumatoid arthritis was found using an alternative experimental approach based on a broad 'functional' genome-wide association study [7], informed in part by knowledge of the linkage results from affected sibling pair analysis [36, 40]. The single-nucleotide polymorphism (SNP) R620W, also denoted rs2476601, is located within the hematopoietic-specific protein tyrosine phosphatase gene, PTPN22.This SNP (C/T) codes for an amino-acid change and the frequency of its minor allele T has been recently and repeatedly shown to be increased in patients with rheumatoid arthritis (RA) [].The allele T confers 1.7- to 1.9-fold increased .
