Because of its role in catecholamine metabolism and several lines of evidence pointing to a locus for psychosis near the COMT gene on chromosome 22q11, we have analysed the COMT Val158Met polymorphism as a candidate susceptibility factor for bipolar affective disorder.

Our results do not show that coding variants of the DRD2 S311C play a major role in conferring susceptibility to major psychoses, but they may be connected with disorganized and delusional symptomatology independently from diagnoses.

Using a sample of sibling pairs discordant for psychosis, the authors attempted to replicate the findings of previous studies suggesting that the functional genetic polymorphism Val158Met in the catechol O-methyltransferase (COMT) gene influences prefrontal cognitive function and increases the risk for schizophrenia.

Genetic polymorphisms of D2-like dopamine receptor genes, DRD2 TaqI A, DRD3 Ser-9-Gly, and DRD4 exon III variable number of tandem repeats, were compared between: (a) MAMP users as a whole and 435 normal controls, and (b) those 154 individuals with MAMP-induced psychosis and the 252 MAMP users with no psychosis.

The individual SNP analysis confirmed an association for the valine/methionine variant with AD-P. Haplotype analyses revealed that the alleles at four loci (rs737865, rs737864, intron 1 C2754delC, rs4680) interacted to create the risk of psychosis in AD, as A-C-C-G haplotype (OR=2.08, 95% CI=1.02-4.27, P=0.044) and G-C-delC-G haplotype (OR=2.54, 95% CI=1.32-4.90, P=0.006) in respect to the most common and not-at-risk A-C-C-A haplotype which was significantly overrepresented in AD-P.
