Sample Status |
A total of 475 unrelated BPD patients (255 men, 220 women) as well as 588 normal controls (178 men, 410 women) were selected from Anhui province. All the patients, 396 (83%) type I BPD and 79 (17%) type II BPD, met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. A final diagnosis was made by two independent psychiatrists on the basis of standardized interview data and hospital case notes.All the patients were ethnic Han Chinese in origin and had signed informed consents. |
Technique |
genotyping |
Statistical Method |
The Hardy-Weinberg equilibrium and other results at single-marker level were determined using SHEsis(Shi and He, 2005). Haplotype analyses were carried out on Haploview4.1 (Barrett et al., 2005). The statistical significance was defined as a P value of less than 0.05. |
Result Summary |
The results provide first evidence for the single nucleotide polymorphism rs778293 in G72 as a potential candidate in altering risk for BPD in the Chinese Han population. |

In conclusion, our experimental data provide further evidence that variations in G72 confer susceptibility to BPD, as well as providing the first such evidence based on an Asian population.
