| 摘要 | Background: A growing body of evidence highlights the existence of shared genetic susceptibility to both major depressive disorder (MDD) and bipolar disorder (BD), suggesting some potential genetic overlap between the disorders. Genome-wide association studies have identified consistent association of single nucleotide polymorphisms of the alpha-1 C subunit of the L-Lype voltage gated calcium channel gene (CACNA1C) with MDD and BD, suggesting CACNA1C as a promising candidate gene for susceptibility to mood disorders. In the present study, we tested the association of CACNA1C with MDD and BD in Han Chinese. Methods: We genotyped three potentially functional polymorphisms in 635 MDD patients, 286 BD patients and 730 normal, control patients. Results: The genotype frequencies of SNP rs1051375 showed statistically significant differences between the BD and control groups (P=0.005). At the allele level, the difference of G allele frequency of rs 105137 5 between BD patients and control subjects was also significant (P=0.011; OR=1.30, 95% CI: 1.06-1.58). We found that GG genotype of rs1051375 carriers had a lower age at onset than those with the AG or AA genotype, and the mean +/- standard deviation ages at onset of GG, AG and AA carriers were 24.04 +/- 4.22, 25.76 +/- 4.75 and 25.78 +/- 4.33 years, respectively. Neither genotype nor allele frequencies of the three polymorphisms were found to be significantly different between the MOD patients and control subjects. Limitations: The relative small sample size in BD group should be considered a limitation of this study. Conclusions: Our initial findings support a potential association of CACNA1C as a genetic risk factor for BD susceptibility. |
