Thank you for your replies to all my questions. It is an overwelming time for us. I had to use polite insistence to actually get to the end diagnosis of CAH. Unfortunately, many doctors try to push other medical conditions off on his autism and it is difficult for them to see beyond it. I think that the reason the CAH may not have manifested with outward signs until the last year and a half or so is because Greg was on a very high dose, experimental, Prednisone treatment for the type of autism (seizure disorder). It basically shut the adrenals down for 18 months. The other issue is that initially the tests for 17-hydroxy progesterone were elevated, but to 191 which is abnormal, but significantly lower than what other patients with CAH at Stanford have. It was not until we did the ACTH test that the adrenals showed the backup and the diagnosis was confirmed. This process took eight months to rule out every other possibility and if I had not questioned how he was in puberty without a change in testosterone, we would not have found the CAH. Just like when I learned about the autism and the seizure disorder, I guess its back to the drawing board to learn about CAH. Thank you for your help, support and suggestions. Jodi
