Study
Hypothesis or Background |
It has been suggested that alteration in the muscarinic-cholinergic system is involved in modulation of mood. Three studies have reported linkage on chromosome 7 with major depressive disorder (MDD) in or close to a region containing the muscarinic receptor CHRM2 gene. A haplotype of SNPs located in CHRM2 (rs1824024-rs2061174-rs324650) has been significantly associated with MDD in a previous study.

Sample Information | clinical depression case-control sample (n = 1420 cases, 1624 controls) |
Method Detail | We report the first study investigating this gene in a large, adequately powered, clinical depression case-control sample (n = 1420 cases, 1624 controls). |
Method Keywords | genotyping |
Result | Our data fail to support association with the CHRM2 polymorphisms previously implicated in the genetic aetiology of depression. |
Conclusions | It is possible our failure to replicate may be a consequence of differences in definition of the MDD phenotype and/or ethnic differences. |
