Like the other forms of CAH, suspicion of severe<unk> -HSD CAH is usually raised by the appearance of the genitalia at birth or by development of a salt-wasting crisis in the first month of life. The diagnosis is usually confirmed by the distinctive pattern of<unk>  steroids: elevated pregnenolone, 17α-hydroxypregnenolone, DHEA, and renin. In clinical circumstances this form of CAH has sometimes been difficult to distinguish from the more common 21-hydroxylase deficient CAH because of the 17α-hydroxypregnenolone elevation, or from simple premature<unk> che because of the DHEA elevation.
