No definite gene for Schizophrenia just yet

BBC featured an article on Schizophrenia; have researchers isolated genes that might somehow contribute to it?

Maybe, maybe not.

Two separate international groups, both testing thousands of people with schizophrenia and healthy volunteers, identified the same two rare genetic variants which appeared to contribute strongly to the chances of developing the disease.

The third research basically found gene types linked to the illness, types that were more common in patients but ones that didn't really increase your chance. Not by a significant amount anyway.

While it is significant, experts are warning that, at this point, there is not enough evidence pinpointing any single gene as the sole cause.
