Abstract:
: Background: Heroin use disorder (HUD) is a complex brain disease that includes multiple phenotypes. Heroin acts primarily as a mu-opioid receptor (OPRM1) agonist. The κ opioid receptor 1 (OPRK1) is critically involved in abstinence and remission. Multiple studies confirm that the OPRM1 and OPRK1 genes are associated with HUD. However, their relationship with the addictive phenotype is still unclear. This study was designed to identify the genetic polymorphisms within OPRM1 and OPRK1 with six HUD phenotypes. Methods: A total of 801 patients with HUD were recruited from the Methadone Maintenance Treatment Program in Xi'an. We identified eight potential functional single nucleotide polymorphisms (SNPs) in the two genes that were genotyped using SNaPshot SNP technology. We then performed a case-control association analysis, investigated particular disease phenotypes, and assessed the extent of epistasis among the variants of the two genes. Results: The OPRK1 rs3802279, rs3802281, and rs963549 genotypes were significantly associated with methadone dosage analyzed by Pearson's chi-square test or binary logistic regression to correct for covariates. The rs3802279 CC, rs3802281 TT, and rs963549 CC genotype carriers required a lower methadone maintenance dose per day. Multifactor dimensionality reduction analysis indicated strong interactions between sex and OPRK1 rs963549. The results of the OPRM1 genotyping did not reveal any associations with the various HUD phenotypes. Conclusion: These findings support an important role of the OPRK1 polymorphism in determining the daily methadone dose and may guide future studies in identifying additional genetic risk factors for HUD.
