My brother has 5 children. Four of them have severe problems which he says is autism. It seems to me that there is more going on. The kids are skeleton thin, their ears are misshapen, their jaws and teeth are also misshapen, they have no coordination and varying types and degrees of mental issues. No one else in our family has anything like this but I worry for my children. Can you hazard a guess as to what is going on? Is this autism?
