title: Exonic polymorphism (rs315952, Ser133Ser) of interleukin 1 receptor antagonist (IL1RN) is related to overweigh/obese with hypertension.
abstract: Recent studies demonstrated that interleukin 1 receptor antagonist (IL-1RN) plays an important role in metabolic effects. To investigate whether IL1RN polymorphisms are associated with obesity, two single nucleotide polymorphisms (SNPs) of the IL1RN gene [rs4251961 (-828, T> C) and rs315952 (Ser133Ser)] were analyzed in 122 overweigh/obese and 123 control subjects. Overweigh/obese subjects were classified according to body mass index (BMI). SNPStats was used to obtain odds ratios (ORs), 95% confidence intervals (CIs), and P values. Multiple logistic regression models (codominant1, codominant2, dominant, recessive, and log-additive) were conducted to analyze the genetic data. Synonymous SNP (rs315952) of the IL1RN gene was associated with overweigh/obese with hypertension (OR= 4.98, 95% CI= 1.74-14.19, P = 0.003 in codominant 1 model and OR= 3.98, 95% CI= 1.48-10.74, P= 0.0029 in dominant model). However, another SNP (rs4151961) did not show association with overweigh/obese or overweigh/obese with hypertension. These results suggest that exonic SNP of IL1RN (rs 315952, Ser133Ser) may be contributed to overweigh/obese with hyper-tension.
