congenital adrenal hyperplasia
Let an agent explain congenital adrenal hyperplasia in general terms, relay types, genetics, screening, emergency adrenal crisis routing and treatment approaches from endocrinology sources, present debates about genital surgery with positions attributed and respectfully, describe the named forms and flag the loosely filed alias, and distinguish CAH from Addison disease, adrenal tumours, androgen insensitivity and polycystic ovary syndrome, without individual medical advice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain congenital adrenal hyperplasia in general terms, relay types, genetics, screening, emergency adrenal crisis routing and treatment approaches from endocrinology sources, present debates about genital surgery with positions attributed and respectfully, describe the named forms and flag the loosely filed alias, and distinguish CAH from Addison disease, adrenal tumours, androgen insensitivity and polycystic ovary syndrome, without individual medical advice.
A group of inherited disorders in which an enzyme needed to make cortisol in the adrenal glands is deficient, causing adrenal enlargement and altered hormone levels, most often 21-hydroxylase deficiency, which accounts for most cases and occurs in classic salt-wasting and simple virilising forms and a milder non-classic form, with rarer forms the registry aliases name such as 11-beta-hydroxylase and 17-alpha-hydroxylase deficiencies; cytochrome b5 deficiency, also listed, is a separate rare condition affecting androgen synthesis or red blood cells and appears loosely filed. Many countries screen newborns because salt-wasting crises can be life-threatening, and lifelong hormone treatment is common. Care for people with atypical genital development is debated, including the timing of surgery, and positions of medical bodies and intersex advocates are attributed.
What it is for: Not applicable; a group of genetic disorders.
It can be explain types and genetics; relay screening and emergency signs; describe named forms; present care debates with attribution.
Distinguishing features
Enzyme deficiency
Cortisol and aldosterone effects
Newborn screening
Lifelong treatment
What it looks like
Varies; may include atypical genitalia at birth, early puberty or no visible signs.
Physical character
21-hydroxylase deficiency share: about 90-95 percent of cases note - attributed
classic CAH incidence: roughly 1 in 10,000-20,000 births note - varies by population
inheritance: autosomal recessive note
How it is recognised
Inherited cortisol synthesis enzyme deficiency
Cytochrome b5 deficiency, salt-wasting 21-hydroxylase deficiency, simple virilising 21-hydroxylase deficiency, 11-beta-hydroxylase deficiency, 17-alpha-hydroxylase deficiency, 21-hydroxylase deficiency
Addison disease is acquired adrenal failure; adrenal tumours are growths; androgen insensitivity affects receptors; PCOS is a common endocrine condition
