Study Design |
case-control |
Study Type |
Candidate-gene association study |
Sample Size |
Four hundred and eighty-four patients (82% are bipolar disorder 1 patients) and 288 controls |
SNP/Region/Marker Size |
5 SNPs |
Predominant Ethnicity |
Mongloid |
Population |
Chinese |
Gender |
273 male and 211 female in BD patients;159 male and 129 female in controls |
Age Group |
average age 39.3 years for BD patients

Detail Info
Sample Diagnosis |
DSM |
Sample Status |
All the patients were of Han Chinese origin and were selected from Wuhu, Anhui Province, China. |
Technique |
genotyping |
Statistical Method |
All the parameters, allele frequencies, Hardy-Weinberg equilibrium (HWE), pair-wise linkage disequilibrium and haplotype analyses were conducted by the online software platform SHEsis, http://analysis.bio-x.cn (Shi and He, 2005). |
Result Summary |
Statistical analysis showed no significant differences in allele or genotype frequencies between control and patient groups. Our results suggest that there is no association between MAOA-LPR genotype and susceptibility to recurrent major depression, bipolar disorder, and schizophrenia in our population. |
