    Abstract:
    AIM: To investigate the association of osteoproterin (OPG) gene polymorphisms 163A/G (rs3102735), 245T/G (rs3134069) with susceptibility to rheumatoid arthritis (RA) in Chinese Han population. OBJECTIVE: To study the correlation between the disease of rheumatoid arthritis (RA) in Chinese Han group and the association of osteoproterin (OPG) gene polymorphisms 163A/G(rs3102735) and 245T/G (rs3134069). Approaches: 205 RA patients and 171 healthy control subjects were participated into this study. Genotype analysis was conducted by polymerase chain reaction-based restriction fragment length polymorphism and was subsequently confirmed by DNA sequencing. Odd ration (OR) and 95% confidence intervals (95% CI) were calculated for the risk of genotype and allele. CONSEQUENCES: OPG gene polymorphisms 163A/G, 245T/G conformed to the Hardy-Weinberg equilibrium. The statistical differences in genotype of AA, AG, GG at 163A/G locus were founded in RA and controls. The G allele was associated with an increased risk of RA, with OR 1.219 (95% CI: 1.066-2.339). According to the observation, there are no significant differences between the RA and control groups with respect to genotype and allele frequencies of OPG gene 245T/G (χ(2)=0.734, 0.518, p>0.05). CONCLUSION: The OPG gene 163A/G SNP may be associated with the susceptibility of RA, G allele may be the risk factor for the development of RA.
