Gene variant linked to schizophrenia, bipolar disorder and alcoholism

Gene variant linked to schizophrenia, bipolar disorder and alcoholism

A rare gene variant discovered by UCL scientists is associated with an increased risk of developing schizophrenia, bipolar disorder and alcoholism, confirms new research.

People with the variant are around 2 to 3 times more likely to develop schizophrenia or alcohol dependence, reports a new UCL study. The variant, which is found in approximately one in every 200 people, is also associated with a threefold risk of developing bipolar disorder, as previously shown by the same UCL group. The research, published in Psychiatric Genetics, is based on genetic analysis of 4,971 people diagnosed with one of the three disorders compared with 1,309 healthy controls. It found that people with the variant of the GRM3 gene, thought to be important in brain signalling, were at increased risk of developing bipolar disorder, schizophrenia and alcohol dependence.

You are my news hero. :smiley: I can’t get the other emoticons to appear. Oh well.

There is a lot of all three of those in this family… Oh those darn genetics.
