Drug addiction is a complex disorder that has a large spectrum of causes. Vulnerability to addiction has been shown in twin studies to have a robust genetic component. This genetic basis for addiction has general and specific components for each drug abused. Although many genes have been implicated in drug addiction, only a handful have either been replicated to have an association or to have an identified functional mechanism related to specific effects of abused drugs. A few selected genetic… 

Pharmacogenetics of addiction therapy.

The elucidation of the role of genetics should aid in the development of new treatments and increase the efficacy of existing treatments for cocaine, alcohol, and opioid dependences.

Opioid Addiction, Genetic Susceptibility, and Medical Treatments: A Review

The biological mechanisms of opioid addiction and medical treatments are summarized, and the polygenic risk score based on the results of a genome-wide association study (GWAS) may be a promising tool to evaluate the association between phenotypes and genetic markers across the entire genome.

Combining research approaches to advance our understanding of drug addiction

It is argued and illustrated with examples that greater awareness of progress in other disciplines can speed up the understanding of the complex processes involved in addiction, which should help the ability to identify who is at increased risk of becoming addicted and the development of prevention and intervention strategies targeted at an individual’s specific needs.

Genética molecular del alcoholismo

There is much more understanding of genetic and epigenetic relationships, and the rapid development of new methods of study promises to continue this process as well as the generation of algorithms for diagnosis, prevention and successful reliable treatments.

Genetic susceptibility of impulse control and related behavior in Parkinson's disease.

A review of genetic studies on ICRBs in the general population and Parkinson's disease will address genetic variants associated with the hyperstimulation of the dopaminergic and serotonergic systems.

Interactions of Endophenotypes & Genotypes

A brief review of this complicated disorder through genotyping and phenotyping aspects, and examines their correlation in creating and driving this disease.

Challenges in Genetic Studies of the Etiology of Substance Use and Substance Use Disorders: Introduction to the Special Issue

The evidence from genetic epidemiologic and molecular genetic studies of problematic use of alcohol, tobacco, and other drugs are reviewed, and the challenges for the next generation of studies of genetic influences on substance use are discussed.

Genotype patterns that contribute to increased risk for or protection from developing heroin addiction

Evidence was found for involvement of five genes in heroin addiction, the genes coding for the μ opioid receptor, the metabotropic receptors mGLUR6 and mGluR8, nuclear receptor NR4A2 and cryptochrome 1 (photolyase-like).



Genes and addiction

The genetic basis of addiction encompasses two broad areas of enquiry: the identification of genetic variation in humans that partly determines susceptibility to addiction and the use of animal models to investigate the role of specific genes in mediating the development of addiction.

Opioid receptor and peptide gene polymorphisms: potential implications for addictions.

Polysubstance abuse-vulnerability genes: genome scans for association, using 1,004 subjects and 1,494 single-nucleotide polymorphisms.

Positive chromosomal markers whose alleles distinguish drug abusers from control individuals in each of two samples are identified, on the basis of pooled-sample microarray and association analyses, and these data support polygenic contributions of common allelic variants to polysubstance abuse vulnerability.

Genetics of alcohol and tobacco use in humans

The results from twin and adoption studies that provide estimations of heritability, the results from chromosomal linkage studies that identify regions of chromosomes that may contain relevant genes, and the results of candidate gene studies are summarized.

A functional polymorphism within the μ-opioid receptor gene and risk for abuse of alcohol and other substances

The findings and analyses suggest that the OPRM1 +118 polymorphism is a general risk gene for substance dependence, but is not specific to a particular substance.

Association of a functional mu-opioid receptor allele (+118A) with alcohol dependency.

The results suggest that, at the molecular level, the endogenous mu-opioid receptor system is a contributing factor to the etiology of alcoholism.

Familial transmission of substance use disorders.

Elevation in risk of drug disorders among the relatives of probands with drug disorders across a wide range of specific substances, including opioids, cocaine, cannabis, and alcohol, which is largely independent from the familial aggregation of both alcoholism and antisocial personality disorder.

Association between alcoholism and the dopamine D4 receptor gene.

Genotype factors that might increase susceptibility by overriding the deterrent showed a higher frequency of a five repeat allele of the dopamine D4 receptor 48 bp repeat polymorphism in alcoholics with ALDH2(2) than in 100 other alcoholics and 144 controls.

μ opioid receptor gene variants: lack of association with alcohol dependence

Data do not support a role of the μ opioid receptor in susceptibility to alcohol dependence, but the potential relationship between OPRM1 genetic variation and response to endogenous opioids and exogenous opiates can now be investigated.

Association between mu opioid receptor gene polymorphisms and Chinese heroin addicts

It is suggested that the variant G allele of both A118G and C1031G polymorphisms may contribute to the vulnerability to heroin dependence.
