abstract：:Since 1969, several classical linkage studies suggested an X-chromosome locus for bipolar affective disorder. However, methods using highly polymorphic DNA markers have provided conflicting evidence for linkage, and an X-chromosomal locus for bipolar disorder remains controversial. More recently, Pekkarinen et al. (19...

abstract：:A polymorphic 44-nucleotide insertion/deletion in the promoter region of the serotonin transporter gene (5-HTTLPR) has been shown to affect the level of expression of the serotonin transporter protein. An association between anxiety-related behavioural traits and the short form of the 5-HTTLPR has been reported. We de...

abstract：:Catechol-O-methyltransferase (COMT) catalyses the methylation, and hence the inactivation, of catecholamines including the neurotransmitters dopamine and noradrenaline. There is evidence implicating COMT as a candidate gene for a number of neuropsychiatric conditions including bipolar disorder. A long recognized popul...

It exists as common high and low activity alleles in the population (determined by a valine 158 methionine polymorphisms), and high red blood cell activity of COMT has previously been associated with schizop...

Because lifetime mania was not assessed, we could not differentiate unipolar from bipolar illness. Having completed such an evaluation in this sample, we now examine three questions: (i) does removing ...
