Association of SOD1 Rs36232792 with Opioid use Disorder and A Novel PCR-RFLP Method For SOD2 Rs5746136

Abstract

Aim: The aim of this study is to find out the effect of SOD1 rs36232792 and SOD2 rs5746136 on the risk of opioid use disorder (OUD). Methods: Individuals with OUD (n = 101) and controls (n = 104) were included. SOD1 rs36232792 was genotyped by PCR. A novel PCR-RFLP method for SOD2 rs5746136 was optimized. Results: A significant difference was observed between individuals with OUD and controls in view of the frequency of ‘Ins/Del+Del/Del’ genotypes of the SOD1 rs36232792 (p = 0.049), but not for SOD2 rs5746136 (p = 0.254). The intensity of anxiety and depressive symptoms was significantly higher in individuals with OUD compared to controls (p = 0.001). Conclusion: The SOD1 rs36232792 polymorphism could contribute to the risk of OUD in a Turkish population. A novel PCR-RFLP method for SOD2 rs5746136 confirmed by sequencing can be used in a research laboratory without advanced equipment.
