Investigation of the STOX1 polymorphism on lumbar disc herniation.

BACKGROUND:Lumbar disc herniation (LDH) is a common musculoskeletal disorder affliction and associated with several genes polymorphism. Storkhead box 1 (STOX1) gene is a transcriptional factor related with several signaling pathways including inflammatory pathway. However, little is known about single-nucleotide polymorphisms (SNPs) of STOX1 associated with LDH risk. METHODS:We conducted a case-control study among 508 LDH cases and well-matched 508 controls, and six candidate SNPs in STOX1 were genotyped by Agena MassARRAY. Chi-squared test, genetic model, and haploview analysis were used to evaluate associations. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional logistic regression. RESULTS:In the allelic model analysis, we found the minor allele "T" of rs7903209 and "A" of rs4472827 were associated with an increased risk of LDH (p = .029, p = .016). Furthermore, in the genotype model analysis, rs7903209 polymorphism was associated with the increased susceptibility of LDH based on dominant (p = .033) and additive model (p = .024); and rs4472827 variant was found to play a harmful role in the LDH risk based on genotype (p = .014), dominant (p = .012), and additive model (p = .015). In the haplotype analysis, the haplotype "GT" in block (rs10998461 and rs10998468) decreased LDH risk (OR = 0.7, 95% CI = 0.52-0.93, p = .016). Functional assessment indicated that rs7903209 and rs4472827 polymorphisms may influence the expression of STOX1. CONCLUSION:Our results provide evidence for polymorphisms of rs7903209 and rs4472827 in STOX1 associated with LDH risk in Chinese Han population. © 2019 The Authors.
