Abstract
Background: Lumbar disc herniation (LDH) is a high incidence spinal disease caused by disc degeneration, nuclear pulse displacement or fiber ring degeneration. This study aimed to explore the correlation between PTPN9 susceptibility and lumbar disc herniation in Chinese Han population.Methods: The subjects were 504 patients with lumbar disc hernia and 503 controls. PTPN9 polymorphism (rs76107647, rs10851882, rs753992, rs11072552) are genotype using Agena MassArray. In addition, Logistic regression was used for odds ratios (ORs) and 95% confidence intervals (CIs) to assess the impact of genetic polymorphisms on LDH occurrence.Results: In the allele model, rs76107647 A (p = 0.023) is associated with a reduced risk of LDH . In the analysis of genetic models, we found that rs76107647 (adjusted, A/A vs. G/G: p = 0.035; A/A vs. AG/GG: p = 0.044; log - additive model: p = 0.022, respectively) and rs11072552 (adjusted, C/C vs. A/A: p = 0.048; C/C vs. CA/AA: p = 0.010, respectively)were significantly related to LDH risk reduction. After age stratification, rs76107647（adjusted, A/A vs. G/G: p = 0.036; A/G vs. G/G: p = 0.008, ; AA/AG vs. G/G: p = 0.002; log–additive model: p = 0.001, respectively) can reduce the risk of LDH for young people ≤ 49 years old, while rs11072552 (adjusted, CC vs. CA/AA: p = 0.009) can significantly reduce the risk of LDH in patients over 49 years old. With gender stratification, rs76107647 (adjusted, A/A vs. G/G: p = 0.017, ; A/A vs. AG/GG: p = 0.019; log - additive model: p = 0.018, respectively) was significantly associated with reduced LDH risk in female. Conclusion: Our research suggests that PTPN9 polymorphisms may have protective effects on the risk of LDH in Chinese Han population.
