MMP-2, TNF-α and NLRP1 polymorphisms in Chinese patients with ankylosing spondylitis and rheumatoid arthritis

Article

Abstract

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are autoimmune, inflammatory diseases with substantial genetic contributions. Matrix metalloproteinase (MMP)-2, tumor necrosis factor (TNF)-α and NLR family pyrin domain-containing 1 (NLRP1) play important roles in the immune response. We studied the MMP-2 rs243865 C/T, TNF-α rs1800629 A/G, NLRP1 rs878329 C/G and NLRP1 rs6502867 C/T polymorphisms in a Chinese cohort of 520 patients with RA, 100 with AS and 520 controls. Genotyping was performed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Using the MMP-2 rs243865 CC homozygote genotype as the reference group, the CT and TT/CT genotypes were associated with significantly reduced risks of AS. However, logistic regression analyses revealed that the MMP-2 rs243865 C/T polymorphism was not associated with risk of RA. TNF-α rs1800629 A/G, NLRP1 rs878329 C/G and NLRP1 rs6502867 C/T polymorphisms were not associated with risk of RA or AS. These findings suggest that the MMP-2 rs243865 C/T polymorphism is associated with AS development.
