Serotonergic polymorphisms in patients suffering from alcoholism, anxiety disorders and narcolepsy.
2001
Abstract 1. Alterations in the serotonergic neurotransmission have been frequently described for patients suffering from alcoholism, anxiety disorders and narcolepsy. 2. The authors tested for association of the 5-HT2A receptor polymorphism (T102C) and the intron 7 tryptophan hydroxylase (TPH) polymorphism (A218C) among 176 alcohol dependent patients, 35 patients with panic disorder, 50 patients with generalized anxiety disorder, 55 patients with narcolepsy and 87 healthy controls. 3. Allele and genotype frequencies of the 5-HT2A receptor polymorphism (T102C), the intron 7 TPH polymorphism (A218C) were almost similar between the patients suffering from alcohol dependence, panic disorder, ge…
The TPH intron 7 A218C polymorphism and TCI dimension scores in alcohol-dependent patients: hints to nonspecific psychopathology
2004
Abstract Aims A linkage of certain alleles of the tryptophan hydroxylase (TPH) intron 7 A218C polymorphism to suicidality and antisocial behaviour has been described. The aim of our study was to find any association between dimensions of the Temperament and Character Inventory (TCI) indicating impulsivity and the TPH polymorphism alleles in unselected alcohol-dependent patients and age-matched controls. Methods We examined 159 alcohol-dependent patients and 161 controls with the TCI and genotyped them for the TPH intron 7 A218C polymorphism alleles. Results Although homozygous TPH genotypes were found more often in alcohol-dependent patients than in controls, an association between TCI dime…
