There is substantial information supporting the role of genetic factors in the susceptibility for alcohol dependence. However, the identification of specific genes that contribute to this predisposition has proven elusive, although several theoretically relevant candidates, e.g. DRD2 or 5-HT1B, have been considered. The difficulty in identifying specific genes may be related to the clinical heterogeneity of the disorder resulting in a poorly defined phenotype for genetic analysis. An…

Fathers' ADS count was associated with higher adolescent risky drinking and conduct problems indirectly via disruption to fathers' and mothers' positive parenting behaviors, whereas mothers'ADS count was not associated with adolescents' risky drinking or conduct problems directly or indirectly viapositive parenting behaviors.

Executive Functions, Memory, and Social Cognitive Deficits and Recovery in Chronic Alcoholism: A Critical Review to Inform Future Research

A review of alcohol-related cognitive impairments affecting component processes of executive functioning, memory, and the recently investigated cognitive domains of metamemory, social cognition, and emotional processing is presented.

Genes associated with alcohol outcomes show enrichment of effects with broad externalizing and impulsivity phenotypes in an independent sample.

A new sample of adolescent and young adult individuals collected as part of the Collaborative Study on the Genetics of Alcoholism finds significant enrichment of effects with sensation seeking, suggesting that this may be a particularly salient behavior associated with risk for alcohol-related problems.

Variance‐components methods for linkage and association analysis of ordinal traits in general pedigrees

A class of variance‐component models for the joint linkage and association analysis of ordinal traits and the maximum likelihood estimators are approximately unbiased, normally distributed, and statistically efficient.

Analysis of alcohol dependence phenotype in the COGA families using covariates to detect linkage

Two mixture models, ordered subset analysis, and a conditional logistic model are applied to genome scan data on the DSM-IV alcohol dependence phenotype on the Collaborative Studies on Genetics of Alcoholism families, and the results are compared to traditional nonparametric linkage analysis.

Joint multipoint linkage analysis of multivariate qualitative and quantitative traits. I. Likelihood formulation and simulation results.

A variance-components method for multipoint linkage analysis that allows joint consideration of a discrete trait and a correlated continuous biological marker in pedigrees of arbitrary size and complexity is described.

Predicting alcohol-related memory problems in older adults: A machine learning study with multi-domain features

Memory problems are common among older adults with a history of alcohol use disorder (AUD). Employing a machine learning framework, the current study investigates the use of multi-domain features to…

Alcohol and aldehyde dehydrogenase polymorphisms and the risk for alcoholism.

The risk for alcoholism in Japanese has been accurately estimated on the basis of the genotype frequencies of ADH2 and ALDH2 and many Japanese may be protected from alcoholism by inactive AL DH2 and by higher frequencies of atypicalADH2.

Alcohol and aldehyde dehydrogenase genotypes and drinking behavior in Japanese.

Together, these studies suggest that the ALDH2*2 allele has an inhibitory effect on drinking behavior, irrespective of the level of alcohol consumption, whereas the effect of the ADH2 polymorphism only becomes apparent in individuals with higheralcohol consumption, such as alcoholics.
