Few medical diagnoses are subject to as much debate as autism. The controversy over whether or not vaccines might cause autism still rages on with all the ferocity of a wildfire. One debate over autism might finally be put to rest: whether or not there is a genetic link that causes the condition. A group of independent scientists from the Yale University School of Medicine and other institutions have identified several gene mutations that drastically increase the risk of autism. However, this research is still in its infancy and it should not be considered a smoking gun. More studies are needed.
