Good. Now even people who don't have schizophrentic relatives can be screened. The NY Times did a writeup of this too:

Schizophrenia is a terrible disease that may make effects on our well-balanced life seriously,even
whittling human natural life to death. From the article,we know schizophrenia is not only caused by family common mutation,but also caused by individual rare mutation. As a result,any one may face the
risk of the disease.
All I hope is that the new methods of its treatment appear out early!

It's a terrible that there are any number of types of schizophrenia,scientists may caused a long period to look for specific pathways.
