Association Between Genetic Polymorphisms of MIR3142HG and the Risk of Steroid-induced Osteonecrosis of the Femoral Head in the Population of Northern China
Abstract Background: Steroid-induced osteonecrosis of the femoral head (ONFH) is aseptic necrosis of the femoral head caused by glucocorticoid use. Once necrotic femoral head necrosis occurs, it irreversibly affects the quality of life seriously. Studies have shown that the susceptibility to steroid-induced ONFH is likely to be related to the variation of miRNA coding genes. Therefore, this study aimed was to investigate the effect of MIR3142HG on steroid-induced ONFH.Methods: Agena MassARRAY was used to genotype MIR3142HG gene rs1582417, rs2431689, rs7727155 and rs17057846 in 199 patients and 506 healthy people. A genetic model and haplotype analysis were used to evaluate the relationship between the MIR3142HG polymorphism and the risk of steroid-induced ONFH. The odds ratio (OR) and 95% confidence intervals (CIs) were obtained through logistic regression to assess the influence of gene polymorphisms on the occurrence of steroid-induced ONFH.Results: The consequences show that rs7727115(OR=0.76,p=0.036) is a protective factor, it could reduce the risk of steroid-induced ONFH, rs1582417(OR=1.28, p=0.041) could increase the risk of steroid-induced ONFH. Stratified analysis , according to each clinical index shows that MIR3142HG TC-CC genotype facilitated the risk of steroid-induced ONFH in male ( p<0.05). In addition, rs2431689 is related to HDL-C(p=0.012) and ApoA1 (p=0.010) levels, and rs17057846 (p=0.024) is related to ApoB levels.The linkage analysis indicated that three SNPs (rs2431689, rs7727115 and rs17057846) in MIR3142HG with significant chain imbalance. In addition, haplotype “GGG” of MIR3142HG was found out is harmful for steroid-induced ONFH.Conclusion: Our results firstly confirm that the genetic polymorphism of MIR3142HG is associated with steroid-induced ONFH susceptibility in Chinese Han population.
