The role of ADAMTS6 and ADAMTS17 polymorphisms in susceptibility to lumbar disc herniation in Chinese Han population

PurposeLDH caused by lumbar disc degeneration is associated with genetic factors. However, the role of ADAMTS6 and ADAMTS17 genes in LDH risk is still unknown.MethodsTo investigate the interaction between ADAMTS6 and ADAMTS17 variants in the susceptibility of LDH, five SNPs were genotyped in 509 patients and 510 healthy individuals. The experiment used logistic regression to calculate odds ratio (OR) and 95% confidence interval (CI). Multi-factor dimensionality reduction (MDR) was chosen to evaluate impact of interaction of SNP-SNP on susceptibility to LDH.ResultsADAMTS17-rs4533267 is significantly associated with reducing risk of LDH (OR = 0.72, 95% CI = 0.57-0.90, p = 0.005). Stratified analysis indicates that ADAMTS17-rs4533267 is significantly associated with the reducing risk of LDH among participants aged <= 48 years old. In addition, we observed that ADAMTS6-rs2307121 was associated with increasing risk of LDH in females. MDR analysis shows that single-locus model composed by ADAMTS17-rs4533267 can be chosen as the best model for predicting susceptibility to LDH (CVC = 10/10, test accuracy = 0.543).ConclusionADAMTS6-rs2307121 and ADAMTS17-rs4533267 are potentially associated with LDH susceptibility. In particular, ADAMTS17-rs4533267 has a strong association with reducing risk of LDH.
