LisaHi Bonnie,
I’m sorry, I don’t have any insight but your post has raised several questions for me. How do you know your son is a DNA carrier? Did you have his DNA tested or just from an ACTH stimulation test? I did not realize that carriers would be symptomatic or that they would be treated with cortef. How long has your son been being treated?
I hope someone has some helpful information for you.
Best wishes.....Lisa
