As I understand it, Non Classical CAH, also called Late Onset CAH or LOCAH, is a milder form of CAH. It involves a partial blockage of the enzyme, 20-50%. 17 ohp levels are high, but not as high as in the more severe forms of CAH, and androgen levels are also high. It does not show up until later in life, rather than at birth--any time from childhood to adult. There is no concern with virilization or adrenal crisis at birth. It is still congenital, involving 2 gene mutations, different than those for SWCAH or SVCAH. The symptoms include early puberty, irregular periods, infertility, hirsutism--things attributed to excess androgens. The treatment includes low doses of glucocorticoids and/or antiandrogens. There is a LOCAH board on this site for those with the disorder. I hope that this helps and that I have explained it accurately.
