Non-Classic Congenital Adrenal Hyperplasia in Childhood: A Review
Sexes, 2023 Congenital adrenal hyperplasia (CAH) is a heterogeneous group of autosomal recessive disorders due to defects in adrenal steroid biosynthesis. In about 90% of patients, CAH is caused by pathogenetic variants in CYP21A2 gene, impairing the function of 21 ...

Classic and current concepts in adrenal steroidogenesis: a reappraisal
Archives of Endocrinology and Metabolism, 2022 Adrenal steroid biosynthesis and its related pathology are constant evolving disciplines. In this paper, we review classic and current concepts of adrenal steroidogenesis, plus control mechanisms of steroid pathways, distribution of unique enzymes and ...

The Use of Routine Laboratory 17-Hydroxyprogesterone for Identification of Cases of 21-Hydroxylase Deficiency Congenital Adrenal Hyperplasia. [PDF]
Clin Endocrinol (Oxf)ABSTRACT Background Clinical outcome studies of 21‐hydroxylase deficiency congenital adrenal hyperplasia (21OHD CAH) may be subject to selection bias due to incomplete case ascertainment. This study aimed to develop a methodology for identifying existing CAH cases and explore its utility to study clinical outcomes. Methods 17‐hydroxyprogesterone assays

Clinical and molecular review of atypical congenital adrenal hyperplasia [PDF]
Annals of Pediatric Endocrinology & Metabolism, 2015 Congenital adrenal hyperplasia (CAH) is one of the most common inherited metabolic disorders. It comprises a group of autosomal recessive disorders caused by the mutations in the genes encoding for steroidogenic enzymes that involved cortisol synthesis ...

JCRPE, 2021 Steroid 21-hydroxylase deficiency is the most common cause of congenital adrenal hyperplasia (CAH), usually due to biallelic variants in CYP21A2. Classical 21-hydroxylase deficiency is characterised by virilisation of the external genitalia in females ...

Monitoring treatment in pediatric patients with 21-hydroxylase deficiency
Frontiers in Endocrinology, 2023 21-hydroxylase deficiency (21-OHD) is the most common form of congenital adrenal hyperplasia. In most developed countries, newborn screening enables diagnosis of 21-OHD in asymptomatic patients during the neonatal period.

Congenital Adrenal Hyperplasias Presenting in the Newborn and Young Infant
Frontiers in Pediatrics, 2020 Congenital adrenal hyperplasia includes autosomal recessive conditions that affect the adrenal cortex steroidogenic enzymes (cholesterol side-chain cleavage enzyme; 3β-hydroxysteroid dehydrogenase; 17α-hydroxylase/17,20 lyase; P450 oxidoreductase; 21 ...

Autoantibodies against Cytochrome P450 Side-Chain Cleavage Enzyme in Dogs (Canis lupus familiaris) Affected with Hypoadrenocorticism (Addison's Disease). [PDF]
PLoS ONE, 2015 Canine hypoadrenocorticism likely arises from immune-mediated destruction of adrenocortical tissue, leading to glucocorticoid and mineralocorticoid deficiency.
