Analysis of genetic variations of protein tyrosine kinase fyn and their association with alcohol dependence in two independent cohorts
<h2>Abstract</h2><h3>Background</h3><p>Decreased sensitivity to and increased tolerance for the effects of alcohol is a phenotype, which was shown to be associated with an increased risk for alcoholism in humans and was observed in protein tyrosine kinase (PTK) fyn knoc...

| Summary: | <h2>Abstract</h2><h3>Background</h3><p>Decreased sensitivity to and increased tolerance for the effects of alcohol is a phenotype, which was shown to be associated with an increased risk for alcoholism in humans and was observed in protein tyrosine kinase (PTK) fyn knockout mice.</p><h3>Methods</h3><p>We performed an association study of genetic variations of PTK fyn in 430 alcohol-dependent patients and 365 unrelated control subjects from two independent samples.</p><h3>Results</h3><p>In a combined analysis, we found an association of alcohol dependence with the single nucleotide polymorphism (SNP) T137346C in the 5′ untranslated region (UTR) of the gene. A relevant association could be excluded for the remaining two informative SNPs. Selection by phenotype showed that a high number of withdrawal symptoms, high amount of alcohol intake, and high maximum number of drinks compared with unrelated control subjects was associated with the SNP in the 5′-UTR region but not with the remaining SNPs.</p><h3>Conclusions</h3><p>Our results indicate a possible association of alcohol dependence with a genotype of the SNP T137346C of the PTK fyn, with C being the risk allele.</p> |
