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.

Expression of Key Androgen-Activating Enzymes in Ovarian Steroid Cell Tumor, Not Otherwise Specified

Journal of Investigative Medicine High Impact Case Reports, 2020
To characterize the expression of steroidogenic enzymes implicated in the development of ovarian steroid cell tumors, not otherwise specified (SCT-NOS). We present 4 ovarian SCT-NOS evaluated by immunohistochemical staining of steroidogenic enzymes as an

Nonsense mutation causing steroid 21-hydroxylase deficiency. [PDF]

Journal of Clinical Investigation, 1988
We determined the sequence of a mutant CYP21B gene isolated from a patient with the severe, "salt-wasting" form of congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency. Codon 318 in this gene is changed from CAG, encoding glutamine, to TAG, a nonsense codon.

Direct molecular diagnosis of CYP21A2 point mutations in Macedonian and Serbian patients with 21-hydroxylase deficiency [PDF]

Journal of Medical Biochemistry, 2015
Background: Steroid 21-hydroxylase deficiency is present in 90-95% of all cases with congenital adrenal hyperplasia (CAH), an autosomal recessive disorder.

Rare Types of Congenital Adrenal Hyperplasias Other Than 21-hydroxylase Deficiency

JCRPE
Although the most common cause of congenital adrenal hyperplasia (CAH) worldwide is 21-hydroxylase deficiency (21-OHD), which accounts for more than 95% of cases, other rare causes of CAH such as 11-beta-hydroxylase deficiency (11β-OHD), 3-beta ...

Congenital adrenal hyperplasia with homozygous and heterozygous mutations: a rare family case report

BMC Endocrine Disorders, 2022
Background Congenital adrenal hyperplasia (CAH), characterized by defective adrenal steroidogenesis, is transmitted in an autosomal recessive manner. Mutations in the steroid 21-hydroxylase gene CYP21A2 causing steroid 21-hydroxylase deficiency account ...

The value of serum levels of dehydroepiandrosterone sulfate as a screening test for late-onset congenital adrenal hyperplasia [PDF]

Einstein (São Paulo), 2006
Objective: To evaluate the use of serum level of dehydroepiandrosteronesulfate as a screening test for late-onset congenital adrenal hyperplasia.Methods: Fourteen hirsute women with elevated serum levels ofdehydroepiandrosterone sulfate, 17 hirsute women

Integration of Adjunctive Therapy for Congenital Adrenal Hyperplasia

Children
CAH represents a prototypical enzyme deficiency disorder, most commonly affecting steroid 21-hydroxylase, in which the critical adrenal pathway from cholesterol to cortisol is blocked [...]

Papulocistic lesions of the face: the tip of the iceberg

Senses and Sciences, 2015
Acne is a manifestation of hormonal overstimulation of the pilosebaceous units of genetically susceptible individuals and may manifest in the form of comedonic, papulopustular or nodular lesions. It can present as an isolated disease or in the context of

Structure of human steroid 21-hydroxylase genes. [PDF]

Proceedings of the National Academy of Sciences, 1986
We have determined the structure of cDNA and two genomic genes encoding steroid 21-hydroxylase [21-OHase; steroid 21-monooxygenase; steroid, hydrogen-donor:oxygen oxidoreductase (21-hydroxylating); EC 1.14.99.10]. If this cytochrome P-450 enzyme is defective, cortisol cannot be synthesized, resulting in congenital adrenal hyperplasia. The cDNA encoding
