CAH results from mutations of genes for enzymes mediating the biochemical steps of production of mineralocorticoids, glucocorticoids, or sex steroids from cholesterol by the adrenal glands (steroidogenesis).

2019年4月16日 · Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders that arise from defective steroidogenesis. The production of cortisol in the zona fasciculata of the adrenal cortex occurs in five major enzyme-mediated steps. CAH results from deficiency in any one of these enzymes.

2025年1月27日 · Congenital adrenal hyperplasia (CAH) refers to a group of autosomal recessive conditions caused by mutations in genes encoding enzymes involved in the production of glucocorticoids, and sometimes mineralocorticoids and sex steroids, from cholesterol in …

Congenital adrenal hyperplasia (CAH) refers to a group of autosomal recessive disorders due to single gene defects in the various enzymes required for cortisol biosynthesis. CAH represents a continuous phenotypic spectrum with over 95% of all cases caused by 21-hydroxylase deficiency.

Table 1 summarises the various forms of CAH, including the related gene variant, and whether there is an excess or deficiency of androgen and mineralocorticoid. 21-hydroxylase deficient CAH is caused by pathogenic variants in both copies (biallelic) of the CYP21A2 gene, which either inactivate or significantly impair its function.

adrenal masses affect 1–4% of normal men and women (148). Their prevalence in autopsy samples increases with age, being 0.2% in young adults and 7% in subjects older than 70 yr (149). a high prevalence of benign adrenal masses has been observed by computed tomography imaging in adults with CaH, especially among those on inadequate GC therapy ...

2024年10月25日 · Congenital adrenal hyperplasia (CAH) encompasses a group of autosomal recessive defects in the enzymes that are responsible for cortisol, aldosterone, and, in very rare cases, androgen synthesis. All forms of CAH are characterized by low levels of cortisol, high levels of ACTH, and adrenal hyperplasia.

Critical Access Hospital (CAH); these must have no more than 25 beds, not counting 10 extra psychiatric beds and 10 extra inpatient rehab beds, and must be located in a rural area or an area treated as rural, be certified by the state as being a necessary provider of healthcare services to area residents, and be more than a 35-mile drive away ...
