Gene in Ethanol Study Datasets

Gene Information

Original ID1:		S67368
Fold Change:		-1.7, -1.4
Note:		Differential expression on the oligonucleotide array (two fold changes are from two case groups)

Dataset Information

Name:		11141048
Method:		Microarray
Tissue:		Frontal cortex
Phenotype:		Alcohol dependence (AD)/Alcohol abuse/Alcoholism
Publication:		Lewohl et al. Alcohol Clin Exp Res. (2000) Gene expression in human alcoholism: microarray analysis of frontal cortex. PubMed
Summary:		RNA was extracted from postmortem samples of superior frontal cortex of alcoholics and nonalcoholics. Relative levels of RNA were determined by array techniques. This study used both cDNA and oligonucleotide microarrays to provide coverage of a large number of genes and to allow cross-validation for those genes represented on both types of arrays. Expression levels were determined for over 4000 genes and 163 of these were found to differ by 40% or more between alcoholics and nonalcoholics.

Dataset Information

Name:		18477577
Method:		Addiction array gene list
Publication:		Hodgkinson et al. Alcohol Alcohol. (2008) Addictions Biology: Haplotype-Based Analysis for 130 Candidate Genes on a Single Array. PubMed
Summary:		To develop a panel of markers able to extract full haplotype information for candidate genes in alcoholism, other addictions and disorders of mood and anxiety. Methods: A total of 130 genes were haplotype tagged and genotyped in 7 case/control populations and 51 reference populations using Illumina GoldenGate SNP genotyping technology, determining haplotype coverage. The 130 candidate genes were selected on the basis of their roles in functional domains important in the addictions and in the related phenotypes of anxiety and depression. The candidate genes included a limited number involved in the pharmacokinetic domain (e.g. several genes in the ADH gene cluster, and ALDH genes). The majority of the genes represent the domains of vulnerability to drug use and pharmacodynamic response. These include dopamine, serotonin, glutamine, GABA, and opioid neurotransmitter genes, signaling genes, and genes modulating stress resiliency and behavioral dyscontrol domains. There is a high degree of overlap between functional gene categories because of pleiotropic actions of molecules on behavior.

Dataset Information

Name:		Literature Search
Method:		Literature search
Summary:		We search all human protein coding gene names and the keywords Alcohol or Ethanol or Alcoholism in the title or abstract of all PUBMED publications. For those gene name less than 3 characters or search result hits more than 100, we use the full name to search again and manually check the results to reduce false positive.

Method:		Literature data mining
Publication:		Wei Yu, Melinda Clyne, Anja Wulf, Ajay Yesupriya, Marta Gwinn and Muin J. Khoury. Phenopedia. HuGE Navigator. Available at: http://www.hugenavigator.net/HuGENavigator/startPagePhenoPedia.do. Accessed [Jun. 10, 2008].
Summary:		HuGE Navigator Phenopedia provides a disease-centered view of genetic association studies summarized in the online Human Genome Epidemiology (HuGE) encyclopedia. We extracted genes associated to 9 Alcohol-related diseases (Alcohol Amnestic Disorder; Alcohol Withdrawal Delirium; Alcohol Withdrawal Seizures; Alcohol-Induced Disorders; Alcohol-Induced Disorders, Nervous System; Alcohol-Related Disorders; Alcoholic Intoxication; Alcoholic Neuropathy; Alcoholism) from HuGE Navigator Phenopedia.
