If one parent has the gene for classic salt-wasting CAH, and the other parent has the gene for nonclassical milder CAH, the child will not get the severe form if he gets both CAH genes from his parents. The milder form gene will compensate and produce enzymes lacking in the severe form's gene. As my endo explained it to me, a child can only get the least severe form of CAH that is carried by his parents. Amandasmom (Maxine)
