In humans, the 36G > T single nucleotide polymorphism (SNP) on KOR gene, that was recently identified, has been found associate with substance dependence, with inconclusive findings.
We detected significant association of the rs1051660 adjusted on metastasis and pain (<i>P</i>=0.02), no other association has been detected between the 7 polymorphisms screened and the dose of morphine needed for pain relief.

The haplotype rs10958350-rs7016778-rs12675595 was associated with gooseflesh skin (global P < 0.0001), yawning (global P = 0.0001), and restlessness (global P < 0.0001) withdrawal symptoms.
The haplotype rs10958350-rs7016778-rs12675595 was associated with gooseflesh skin (global P < 0.0001), yawning (global P = 0.0001), and restlessness (global P < 0.0001) withdrawal symptoms.
Three SNPs of OPRK1, rs16918875, rs702764 and rs963549, were identified in the population, none of which showed significant association with addiction.
However, OPRK1 SNP rs6473797 was significantly related to the severity of alcohol-related symptoms as measured by AUDIT and OCDS and a haplotype containing rs6473797 was also related to OCDS scores in AUD patients.
Furthermore, rs6985606 had the only significant association with the co-incidence of insomnia and libido dysfunction in the methadone maintenance treatment group (p = 0.038).
According to the single locus analyses, rs997917 and rs6985606 represented significant associations with opium addiction under recessive (p = 0.0128) and co-dominant (p = 0.0001) inheritance models, respectively.

SNPs in two opioid receptor genes in the infants were associated with worse NAS severity: (1) The PNOC rs732636 A allele (OR=3.8, p=0.004) for treatment with 2 medications and a longer hospital stay (LOS) of 5.8 days (p=0.01), and (2) The OPRK1 rs702764 C allele (OR=4.1, p=0.003) for treatment with 2 medications.
Three SNPs of OPRK1, rs16918875, rs702764 and rs963549, were identified in the population, none of which showed significant association with addiction.
The strongest predictive factors were rs5326 in <i>DRD1</i>, which was associated with increased odds of ICDs, and rs702764 in <i>OPRK1</i>, which was associated with decreased odds of ICDs.
To date few studies have explored the potential impact of the OPRM1 A118G polymorphism on the pharmacological effects of buprenorphine (BPN), a potent MOR partial agonist and kappa opioid receptor antagonist, which is approved by the FDA for the treatment of opioid addiction and chronic pain.
Polymorphism A118G of opioid receptor mu 1 (OPRM1) is associated with emergence of suicidal ideation at antidepressant onset in a large naturalistic cohort of depressed outpatients.
The AA genotype of rs4680 or A_T_C_A/ A_T_C_A (rs6269_rs4633_ rs4818_rs4680) diplotype of COMT, combined with the AG genotype of OPRM1 A118G, showed significantly increased pressure pain threshold from butorphanol.
Epistatic effects between variants of kappa-opioid receptor gene and A118G of mu-opioid receptor gene increase susceptibility to addiction in Indian population.
