"As well as implicating a specific gene, SLC6A1, for the first time 
in schizophrenia, our findings suggest that new mutations in genes 
that are important in brain development can be a major factor in some 
cases and that these mutations can also increase the risk of other 
disorders such as autism and developmental delay."

"As well as understanding how the mutations impact on brain function, 
it will be important to understand what factors modify their effects 
as these may also be possible targets for new treatments."

Globally, schizophrenia affects about 1% of the population and is 
among the top 15 leading causes of disability.

In the United States, estimates suggest about 1.5 million people live 
with the condition.
