Detail Info
Sample Diagnosis |
DSM-IV |

Result Summary |
Screening of bipolar affective disorder patients for mutations in TRPM2 led to identification of three novel and four known transitions. Two transitions resulted in the substitutions: R755C and A890V. Screening of the coding sequence of ADARB1 did not reveal any mutations except one already known transition. A comparison of the transition frequency in patients and controls does not support association of the detected mutations with bipolar affective disorder. According to our results, bipolar affective disorder may not be caused by mutations in ADARB1. However, this study does not exclude TRPM2 as a candidate gene since we have screened only about 30 per cent of the entire coding sequence of this large gene. |

We detected three novel c.C>T transitions in TRPM2 and one of them (c.2769C>T) led to a rare substitution A890V. However, these findings do not support an association of the transitions with the disorder.
