Table 2 TNF-RI A36G single nucleotide polymorphism genotype frequencies and sTNFR levels

From: Polymorphism in the tumour necrosis factor receptor II gene is associated with circulating levels of soluble tumour necrosis factor receptors in rheumatoid arthritis

Genotype n (%) sTNF-RI (pg/ml) sTNF-RII (pg/ml)
Early RA
AA 41 (39.8) 1,543 ± 597 4,435 ± 1,898

GG 12 (11.7) 1,303 ± 447 4,566 ± 1,490
Established RA
AA 48 (31.8) 1,827 ± 758 5,740 ± 1,942
AG 70 (46.4) 1,688 ± 674 5,475 ± 2,020

  1. Shown are tumor necrosis factor receptor I (TNF-RI) A36G single nucleotide polymorphism genotype frequencies and soluble tumor necrosis factor receptor (sTNFR) levels in rheumatoid arthritis (RA) patients with early (n = 103) and established (n = 151) disease. sTNFR levels are expressed as the mean ± standard deviation. No significant differences in sTNFR levels were found between any of the genotypes in either population. sTNF-RII, soluble tumor necrosis factor receptor II.
