Genotype frequencies of functional polymorphisms in the genes encoding the serotonin transporter (5-HTT) and the enzyme catechol-O-methyltransferase (COMT) were not different in 51 suicidal inpatients compared to 51 control subjects. Within the patient group, increased hopelessness and suicide ideation were associated with homozygosity of the 5-HTT high promotor activity allele. (C) 2000 Elsevier Science Ireland Ltd.
