Study
Hypothesis or Background |
The chromosomal region 12q24 has been previously implicated by linkage studies of both bipolar disorder and unipolar mood disorder and we have reported two pedigrees segregating both bipolar disorder and Darier's disease that show linkage across this region. The gene P2RX7 is located in this chromosomal region and has been recently reported as a susceptibility gene for bipolar disorder and unipolar depression. The non-synonymous SNP rs2230912 (resulting in amino-acid polymorphism Q460R) showed the strongest association and has been postulated to be pathogenically relevant.

Sample Information | UK case-control sample (bipolar I disorder N = 687, unipolar recurrent major depression N = 1,036, controls N = 1,204) |
Method Detail | We have investigated this gene in a large UK case-control sample (bipolar I disorder N = 687, unipolar recurrent major depression N = 1,036, controls N = 1,204). |
Method Keywords | genotyping |
Result | Neither rs2230912 nor any of 8 other SNPs genotyped across P2RX7 was found to be associated with mood disorder in general, nor specifically with bipolar or unipolar disorder. Further, sequencing of our two chromosome 12-linked bipolar-Darier families showed no evidence of rare variants at P2RX7 that could explain the linkage. |
Conclusions | Our data do not provide support for rs2230912 or the other polymorphisms studied within the P2RX7 locus, being involved in susceptibility to mood disorders. |
