Mutated gene raises autism risk, US study finds:
People with two copies of the mutated gene [MET] have 2 to 2.5 times the normal risk of autism and people with one mutated copy have 1.7 times the risk, he said.
...
Levitt said the mutation does not change the function of the gene, but changes gene expression -- how active the gene is.
The study is going to be published in
PNAS.
