" It is my understanding that both parents have to be carriers to have a child with CAH.  Otherwise if only one has a mutation and the pass it on to the child the child would only be a carrier as well."

Haven’t had my other three children checked for carrier status but they were never at risk to have CAH as their Father is not a carrier, so we didn’t have the worry when I was pregnant.  We were lucky that Chloe did not inherit CAH really I feel. :)
