| Statistical Method |
Hardy-Weinberg Equilibrium (HWE) and haplotype block structure were examined using Haploview, version 3.2. Association of individual SNPs with BD was tested using 2*2 or 2*3 contingency tables and X2 tests. Association between the haplotypes and diagnostic groups was tested using COCAPHASE within the UNPHASED suite of programs. The p-values for tests of allelic and genotype association were conservatively corrected for multiple testing using the Bonferroni method. |
| Result Summary |
The A allele of the NDUFV2 SNP rs1156044 was significantly associated (Bonferroni-corrected) with BD (p = 0.013) but differed in allele (rs1156044 G allele) from that previously reported as associated with BD. There was a trend for elevated BLCL [Ca2+]sub>B associated with SNP rs977581 in BD patients, but NDUFV2 mRNA levels in BLCLs did not differ between patients and controls, nor represented genotypes. |

| NDUFV2 |
Statistically significant increased frequency of allele A of the SNP rs1156044 was observed in the BD group as a whole [84.7%; odds ratio (OR) = 2.44, p = 0.013) and in the BD I subgroup (85.3%; OR = 2.55, p = 0.014), compared to healthy controls (69.4%)..

While genetic variants of NDUFV2 may increase risk for BD, the role of its altered expression and the link to intracellular Ca<sup>2+</sup> abnormalities in BD remains equivocal.
