|Brief Title ICMJE||Natural History Study of Patients With Excess Androgen|
|Official Title ICMJE||Natural History Study of Patients With Excess Androgen|
This study will evaluate and gather information in patients with genetic causes of too much androgen (male-like hormone) in order to better understand the effects of too much androgen and describe problems associated with it. Too much androgen in childhood, if untreated, results in rapid growth and early puberty with early cessation of growth and short stature in adulthood. Too much androgen in adulthood may result in infertility, and women may have excess facial hair, acne and a more male-like appearance. Excess androgen may also affect mood and behavior and possibly the secretion of other hormones, such as insulin. Two genetic diseases that result in early childhood androgen excess are congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP).
Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11- hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency and males with known or suspected FMPP may be eligible for this study. Patients with both classic and non-classic CAH are eligible, and patients with androgen excess of unknown cause may be eligible.
Participants undergo the following procedures:
The schedule for these procedures varies. In a part of the study involving only patients with CAH, growing children are evaluated twice (once in childhood and once after reaching adult height), and adults are evaluated once. In another part of the study involving patients with CAH and FMPP, growing children are seen twice a year, and adults and children who have reached adult height may be seen annually. Additional visits may be scheduled if medically indicated. In this part of the study, females are asked to keep a record of their periods after their first menstrual cycle.
|Detailed Description||Androgen excess in childhood results in pseudoprecocious puberty, accelerated childhood growth with premature epiphyseal fusion, adult short stature, and unknown metabolic and psychological perturbations. Congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP) are two genetic diseases that result in early childhood androgen excess, and CAH due to 21-hydroxylase deficiency is the most common cause of hyperandrogenism in childhood. This protocol will elucidate a comprehensive phenotypic profile for patients with CAH and FMPP. Data will be collected in a large cohort of patients regarding growth and development, hormonal and metabolic factors and psychological characteristics. This protocol will allow investigators to compare patients with androgen excess of different etiologies, elucidate androgen-mediated and disease-specific phenotypic characterizations, and allow the investigators to acquire further knowledge for use in the design of future therapeutic interventions.|

|Eligibility Criteria ICMJE||
Males with known or suspected FMPP.
Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11-hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency. Classic and nonclassic patients are eligible.
Patients with excess androgen of unknown etiology.
Relatives of patients with CAH and FMPP.
Females with isolated polycystic ovary syndrome. If, following a diagnostic work-up, a patient is determined to have PCOS as the only cause of her hyperandrogenism; she will no longer be followed on this protocol.
Patients with significant nonendocrine medical conditions.
