Gene Information

Dataset Information

Name:		12774316
Method:		Microarray
Tissue:		Temporal cortex
Phenotype:		Alcohol dependence (AD)/Alcohol abuse/Alcoholism
Publication:		Sokolov et al. J Neurosci Res. (2003) Transcription profiling reveals mitochondrial, ubiquitin and signaling systems abnormalities in postmortem brains from subjects with a history of alcohol abuse or dependence. PubMed
Summary:		To identify candidate mechanisms for alcohol abuse, the expression of 12,626 genes was measured in postmortem temporal cortex from 11 subjects with a history of alcohol abuse or dependence, with or without other psychiatric diagnoses and compared pairwise with the expression in 11 nonalcoholic subjects matched for the other psychiatric diagnoses and demographics. Genes were defined to have altered expression in alcohol abuse if: 1) the gene showed decreased expression in at least 10 of 11 subjects with alcohol abuse, or showed increased expression in at least 10 of 11 subjects with this diagnosis compared to matched non-abusers (P<0.007, X2test); or 2) the difference in the mean abuser/non-abuser ratio for the gene from value of 1.0 was significant at P<0.05 (one sample t-test). In subjects with a history of alcohol abuse or dependence, 163 genes were changed significantly.

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.

Region:		92691777-121646580
Phenotype:		ADSX (number of DSM-IV AD symptoms)
Name:		16534506
Method:		Linkage
Publication:		Prescott et al. Mol Psychiatry. (2006) Genomewide linkage study in the Irish affected sib pair study of alcohol dependence: evidence for a susceptibility region for symptoms of alcohol dependence on chromosome 4. PubMed
Summary:		We conducted a genome scan in the Irish Affected Sib Pair Study of Alcohol Dependence (IASPSAD). A 4 cM genome scan was conducted using 474 families of which most (96%) were comprised by affected sib pairs. Nonparametric and quantitative linkage analyses were conducted using DSM-IV alcohol dependence (AD) and number of DSM-IV AD symptoms (ADSX). Quantitative results indicate strong linkage for number of AD criteria to a broad region of chromosome 4, ranging from 4q22 to 4q32 (peak multipoint LOD=4.59, P=2.1 x 10(-6), at D4S1611). We got the gene list in the region between two markers D4S423 and D4S427 as markers between (included) these two markers have LOD scores >2 with P value <0.0003.
