Aim: The genetic components of the schizophrenia susceptibility are calculated as being 50%. We evaluated the frequency of alleles and genotypes of COMT and MAO-A genes polymorphisms in patients with schizophrenia and in the healthy population. We searched for the associations between genotypes and PANSS results among patients in a three month antipsychotic therapy.

This polymorphism was investigated in two types of studies: (1) the association study in a whole group of alcoholics (116 patients fulfilling ICD-10 alcohol dependence (AD) criteria and 255 controls, Polish descent) and homogenous overlapping subgroups of patients with: a history of delirium tremens and/or alcohol seizures, early age of onset of alcoholism (AOO<26 years), a co-occurrence of dissocial personality disorder, a history of familial alcoholism; (2) the family-based study (using Transmission Disequilibrium Test (TDT) in 100 Polish families with alcohol dependence). The history of alcoholism was obtained using SSAGA (Polish version).

Method: The Cloninger Temperament and character Inventory was applied to 52 eating disordered patients (33 with anorexia nervosa and 19 with bulimia nervosa).
The associations between 5-HTT-linked polymorphic region (5-HTT-LPR), monoamine oxidase A (MAOA)-LPR and the dimensions of temperament evaluated using the Temperament and Character Inventory (TCI) and NEO Five-Factor Inventory (NEO-FFI) were studied. One hundred healthy volunteers (without psychiatric disorders) were recruited to represent a cross-section of the population of Szczecin (Poland) in terms of sex, age and education. No associations between 5-HTT-LPR and the TCI harm avoidance dimension and between 5-HTT-LPR and the NEO-FFI neuroticism dimension were found.
