| Study Design |

| Study Type |
Candidate-gene association study |

| SNP/Region/Marker Size |
5 SNPs |
| Predominant Ethnicity |

Detail Info
| Sample Diagnosis |
DSM |
| Replication Size |
263 BPAD patients and 430 controls |
| Technique |
genotyping |
| Statistical Method |
The transmission-disequilibrium test(TDT) was applied for the triad analysis. We used the Armitages trend test8 for the case-control study and the FAMHAP program for the haplotype analysis. Fisher's method of the'combination of probabilities from tests of significance' was used to determine the common significance of the case-control sample and the trio sample. |
| Result Summary |
We observed no significant TDT results in TRAR1 and TRAR5.The combined analysis of both samples with rs8192624 resulted in a significant association (P=0.004).Our study provides evidence for the involvement of the TRAR4 locus in the etiology of BPAD. |
