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).\n\nPatients 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.\n\nParticipants undergo the following procedures:\n\n* Medical history and physical examination.\n* Fasting blood tests for analysis of hormones, blood chemistries including blood sugar and cardiovascular risk factors such as lipids.\n* Oral glucose tolerance test for patients with elevated insulin levels. For this test, a catheter (plastic tube) is placed in a vein in the patient's arm. The patient drinks a sugar-containing fluid and blood samples are collected through the catheter at intervals starting with drinking the solution, and then 30, 60 and 120 minutes after drinking the solution.\n* 24-hour urine collection to measure hormone levels in the urine.\n* DNA testing for patients with 21-hydroxylase deficiency to help identify the type of genetic mutation responsible for the disease.\n* X-ray of the left hand to measure bone age in growing children. The x-ray is used to determine how far into puberty the child is and how much growth potential is left in the bones.\n* A pelvic ultrasound in females and testicular ultrasound in males to evaluate the size and development of the gonads (ovaries in females and testes in males).\n* Cognitive and psychological tests, including an IQ test and evaluation of memory, achievement and behavior.\n* Other tests and evaluations based on medical need.\n\nThe 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.\n\n...", 'detailedDescription': 'Study Description:\n\nAndrogen 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\n\ntherapeutic interventions.\n\nObjective:\n\nTo elucidate a comprehensive phenotypic profile for patients with CAH and FMPP.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '99 Years', 'minimumAge': '1 Day', 'genderBased': True, 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Individuals with excess androgen, CAH, FMPP as well as their parents.', 'genderDescription': 'Males, ages 0 - 99 with known or suspected FMPP', 'healthyVolunteers': False, 'eligibilityCriteria': '* INCLUSION CRITERIA:\n\n 1.
