In multivariable analyses adjusting for indoor tanning frequency, appearance orientation, and depressive symptoms, variant genotypes (CC or CT) in two DRD2 dopamine receptor gene SNPs were associated with increased odds of indoor tanning addiction (rs4436578, odds ratio [OR]: 2.30, 95% confidence interval [CI]: 1.11-4.77; rs4648318, OR: 1.95, 95% CI: 1.02-3.72).

Unlike previous research from India as well as abroad, the predominance of B1 allele of rs1079597 in patients with schizophrenia and absence of Cys311 in all study participants is a salient difference.
The enhancer rs12364283</span> occurs more frequently in heroin-dependent cases than controls (MAF 13% vs. 7%, respectively), revealing significant association with heroin addiction (p = 3.0E-06, OR 2.1).
A total of 7 gene polymorphisms from DRD2 (rs1800497, rs1079597, rs1800498, rs1801028) and 5-HT2 A (rs6313, rs6311, rs6305) were genotyped for their association with schizophrenia.
An OXTR-DRD2 interaction (rs2268498 × rs1801028) was identified to confer risk of provisional PTSD diagnosis (OR = 9.18, 95% CI = 3.07-27.46 and P = 7.37e-05) and further subset analysis indicated that rs2268498 genotypes controlled the association directions of rs1801028 and rs1801028 genotypes also controlled the association directions of rs2268498.
The influence of DRD2 rs2283265 and DRD4 48 bp VNTR in exon 3 variants, as well as their interaction on crack cocaine addiction susceptibility and severity were evaluated in women and men separately.
To determine whether genetic polymorphisms related to pharmacodynamics with metabolic adverse effects, namely leptin promoter (<i>LEP</i>) rs7799039, leptin receptor rs1137101, dopamine D2 rs4436578, serotonin 5-HT2A rs6313, and serotonin 5-HT2C rs518147 and rs12836771, are associated with hyperglycemia induced by risperidone or clozapine in adult Thai patients with psychosis.

According to the allele, genotype and haplotype frequency analysis, we observed an association between HD and several DRD2/ANKK1 polymorphisms (rs1800497, rs1800498, rs1079597 and rs4648319); this was most notable in the late-onset HD subgroup.
Subsequent depression-stratified analysis of rs6276 in DRD2 revealed that patients with the A/A genotype had higher pain scores than did those with the G/G genotype (P = 0.043).
In the present study, we aimed to investigate the relationship between developmental stuttering in children and the levels of serum homovanillic acid (HVA), dopamine D2 receptor (DRD2) C957T (rs6277), and solute carrier family 6 member 3 (SLC6A3) human dopamine transporter (hDAT) A559V (rs28364997) single-nucleotide polymorphisms.
This study is the first study to determine the allele frequency and the genetic association of the <i>DRD2</i> rs1076560 SNP and <i>OPRM1</i> rs1799971 SNP variants in clinically diagnosed patients with SUD from the United Arab Emirates (UAE).
In 128 female patients of the recruited UCC cohort, patients who carried at least one deletion allele of <i>DRD2</i> rs1799732 showed a higher incidence of having an invasive stage (AOR=2.585, 95% CI: 1.066~6.264, <i>p</i>=0.032) and a large tumor (AOR=2.778, 95% CI: 1.146~6.735, <i>p</i>=0.021).
The rs1800498 polymorphism has shown an association with drug abuse in which a higher frequency of the allelic T form was observed in the whole group of patients and selected subgroups with concomitant opiates or cannabis abuse history when compared with the controls.

Analysis revealed an influence of rs4245146 of the dopamine D2 receptor (DRD2) gene on the BIS-11 attention first-order factor, such that self-reported attentional impulsiveness increased in an additive fashion with each copy of the T allele.
The major allele A of rs2511521 located in DRD2 (OR = 3.1(95% CI 1.1-8.2)) and the minor allele T of rs625413 located in TIRAP (OR = 2.5(95% CI 1.1-5.8)) in NFO subjects significantly associated with increased risk of food addiction.
This work has implications for a number of psychiatric conditions in which dopamine signaling and variation in C957T status have been implicated, including schizophrenia and substance use disorders.
