Sample Diagnosis |
DSM-IV |
Sample Status |
The sample consisted of 213 unrelated cases recruited through Scottish psychiatric hospitals and 197 controls, all white Scottish Caucasians. Patients met Diagnostic and Statistical Manual of Mental Disorder-IV criteria exclusively for bipolar I disorder, as defined by the OPCRIT program and based on case-note review and clinical interview with semistructured diagnostic questionnaires. |
Technique |
genotyping |
Statistical Method |
All SNPs were in the Hardy-Weinberg equilibrium. They analysed the polymorphisms allele-wise, genotype-wise and, for each gene, haplotype-wise. Chi-square analysis was used. |
Result Summary |
We analysed the polymorphisms allele-wise, genotype-wise and, for each gene, haplotype-wise but obtained no result that reached nominal significance (p<0.05) for an association with the disease status. In conclusion, we could not find evidence of association between RGS4, PRODH, COMT and GRK3 genes and bipolar affective disorder 1 in the Scottish population. |
