2) Simple virilizing
3) Non-classic
4) All of the above

Answer 1

The most common type of congenital adrenal hyperplasia is the non-classic form, which can present later in life with milder symptoms and is often not detected at birth.

Step-by-step explanation:

The most common type of congenital adrenal hyperplasia is the non-classic form. Congenital adrenal hyperplasia (CAH) is a group of inherited genetic disorders that affect the adrenal glands. It involves a deficiency in enzyme 21-hydroxylase. The non-classic form of CAH is a milder form that can present later in life and is often undetected at birth. Symptoms may include abnormally low levels of cortisol and, in some cases, abnormally low levels of aldosterone, leading to various clinical presentations such as early signs of puberty, hirsutism, and fertility issues.
