Funded Activity Summary

Bipolar disorder (manic depressive illness) is a severe mood disorder, with a lifetime prevalence of up to 1.6%. The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more clearly the biological basis of bipolar disorder as a necessary prerequisite to improved diagnosis and treatment. The underlying causes of bipolar disorder remain unknown. However, family studies reveal the high heritability of bipolar disorder and this familial clustering provides an opportunity to use genetic approaches to identify the predisposing genes. The long-term aim of our research is to investigate the biology of those genes that either cause or predispose to bipolar disorder. We have previously reported strong evidence for a novel bipolar disorder susceptibility gene on chromosome 4, a finding which has subsequently been reproduced in several independent studies. Consequently, we hypothesise that there is a gene located on chromosome 4 that predisposes to bipolar disorder. The aim of this proposal is to identify the chromosome 4 bipolar susceptibility gene and understand how the gene causes bipolar disorder. Identifying the genes responsible for bipolar disorder will allow us to define and understand the biological basis of this severe psychiatric condition. This will ultimately lead to major improvements in the ability to diagnose, treat and prevent the illness.
