Schizophrenia could be caused by a wide variety of DNA mutations

Additional coverage of same two studeis:

A wide variety of DNA mutations which differ from one person to another might play a decisive role in triggering schizophrenia according to two of the largest studies to date into the complex genetics of the mental disorder. Doctors have long realised that there is a strong genetic component to schizophrenia, which affects one in 100 people at some time in their lives and tends to run in families, but the search of the “schizophrenia gene” has proved elusive. Two independent studies that have analysed the DNA sequences of patients and their parents – and compared them to healthy individuals – have found sets of key mutations that seem to interfere with the development of healthy nerve communications in the brain.
