Auto-antibodies, HLA and PTPN22: susceptibility markers for rheumatoid arthritis

Modeling of PTPN22 and HLA-DRB1 susceptibility to rheumatoid arthritis

In the present paper, we used the North American Rheumatoid Arthritis Consortium data provided for Genetic Analysis Workshop 15 Problem 2 to: 1) estimate the penetrances of PTPN22 and HLA-DRB1 and, 2) test the selected model of PTPN22 conditional on the rheumatoid factor status. To achieve these aims, we used the marker association segregation chi-square method, fitting simultaneously both geno...

PTPN22: a confirmed rheumatoid arthritis susceptibility gene?

Role of HLA-DRB1, PTPN22, CTLA4 Gene Polymorphisms in Susceptibility to Rheumatoid Arthritis

Lack of Association between PTPN22 (+1858 C>T) rs2476601 polymorphism and susceptibility to rheumatoid arthritis (RA) in Northeast of Iran

Background and objectives: Rheumatoid arthritis (RA) is an autoimmune disease with a complex genetic background. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a lymphoid specific protein tyrosine phosphatase which is involved in negative regulation of T cell response. Several studies have assessed the association between PTPN22 single nucleotide polymorphisms (SNPs) with RA ...

Antikeratin antibodies: diagnostic and prognostic markers for early rheumatoid arthritis.

Antibodies to the stratum corneum of rat oesophagus (antikeratin antibodies) were assayed by indirect immunofluorescence in a prospective study of patients with early rheumatoid arthritis (RA). At the beginning of the study, antikeratin antibodies of IgG class were detected in serum samples from 27/71 (38%) patients compared with 1/20 (5%) control patients with reactive arthritis, and 1/38 (3%)...
