Phenotypic variability of hyperandrogenemia in females heterozygous for CYP21A2 mutations

Indian Journal of Endocrinology and Metabolism, 2014
Objectives: The objective was to seek evidence on the prevalence and consequences of heterozygous CYP21A2 mutations in girls, adolescent, and adult females with clinical manifestation of androgen excess.

Molecular genetic analysis of CYP21A2 gene in patients with congenital adrenal hyperplasia

Indian Journal of Endocrinology and Metabolism, 2012
Context: Congenital adrenal hyperplasia (CAH) is one of the inborn errors of metabolic disorder inherited in an autosomal recessive manner caused by the defects in the steroid 21 hydroxylase CYP21A2 gene.

Co-existence of Congenital Adrenal Hyperplasia and Familial Hypokalemic Periodic Paralysis due to CYP21A2 and SCN4A Pathogenic Variants

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 ...

Caracterización molecular de la nueva entidad clínica relacionada con la hiperplasia suprarrenal congénita, síndrome CAH-X en población española

Advances in Laboratory Medicine, 2023
La recombinación entre CYP21A2-TNXB y sus respectivos pseudogenes (CYP21A1P-TNXA) da lugar a quimeras responsables del síndrome CAH-X (SCAH-X). Los pacientes con este síndrome presentan manifestaciones clínicas de hiperplasia suprarrenal congénita (HSC ...

Molecular characterization of the new clinical entity associated with congenital adrenal hyperplasia: the CAH-X syndrome in the Spanish population

Advances in Laboratory Medicine, 2023
The chimeras causing the CAH-X syndrome (SCAH-X) result from recombination between CYP21A2-TNXB and their respective pseudogenes (CYP21A1P-TNXA). The clinical manifestations of this syndrome include congenital adrenal hyperplasia (CAH) and Ehlers–Danlos ...

17-Hydroxyprogesterone Response to Standard Dose Synacthen Stimulation Test in CYP21A2 Heterozygous Carriers and Non-carriers in Symptomatic and Asymptomatic Groups: Meta-analyses

JCRPE, 2022
INTRODUCTION: Standard dose synacthen stimulation test (SDSST) is a gold standard screening test for evaluating adrenal gland function. Despite studies using SDSST to identify heterozygosity in CYP21A2, the reliability of the test for this purpose is ...

A 4-hour Profile of 17-hydroxyprogesterone in Salt-wasting Congenital Adrenal Hyperplasia: Is the Serial Monitoring Strategy Worth the Effort?

JCRPE, 2022
INTRODUCTION: Objective: Since there is no gold standard laboratory variable for adjustment of treatment in congenital adrenal hyperplasia (CAH), the aim was to assess the use of a 4-hour profile of serum 17-hydroxyprogesterone (17-OHP) to determine the ...

Allele-specific and multiplex PCR based tools for cost-effective and comprehensive genetic testing in Congenital Adrenal Hyperplasia

MethodsX, 2022
Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder due to enzyme defects in adrenal steroidogenesis. Several genes code for these enzymes, out of which mutations in the CYP21A2 gene resulting in 21 hydroxylase deficiency, contribute ...

Functional studies of p.R132C, p.R149C, p.M283V, p.E431K, and a novel c.652-2A>G mutations of the CYP21A2 gene [PDF]

, 2014
Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is the most frequent inborn error of metabolism and accounts for 90–95% of CAH cases.
