HIV Drug Efavirenz Inhibits CYP21A2 Activity with Possible Clinical Implications [PDF]

open access: yesHormone Research in Paediatrics, 2019
<b><i>Background:</i></b> The HIV drugs lopinavir and ritonavir have recently been reported to cause transient adrenal insufficiency in preterm newborns. We, therefore, considered HIV drugs as a cause of transiently elevated 17-hydroxyprogesterone (17OHP) levels in a neonatal screening test for congenital adrenal hyperplasia in ...

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Synthesis of halogenated pregnanes, mechanistic probes of steroid hydroxylases CYP17A1 and CYP21A2 [PDF]

open access: yesThe Journal of Steroid Biochemistry and Molecular Biology, 2012
The human steroidogenic cytochromes P450 CYP17A1 (P450c17, 17α-hydroxylase/17,20-lyase) and CYP21A2 (P450c21, 21-hydroxylase) are required for the biosynthesis of androgens, glucocorticoids, and mineralocorticoids. Both enzymes hydroxylate progesterone at adjacent, distal carbon atoms and show limited tolerance for substrate modification.

Genetic Insights and Lifelong Management of Aldosterone Synthase Deficiency: A Case of Hyperreninemic Hypoaldosteronism

open access: yesClinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Aldosterone synthase deficiency is a rare cause of neonatal salt‐wasting and failure to thrive. Routine newborn electrolyte screening after 5 days of life is vital for early detection and prevention of life‐threatening crises. Genetic confirmation enables targeted fludrocortisone therapy, ensuring favorable growth and developmental outcomes.

Rapid detection of common variants and deletions of CYP21A2 using MALDI-TOF MS Short title: CYP21A2 genotyping using MALDI-TOF MS

open access: yes, 2023
Abstract Background Newborn screening (NBS) for congenital adrenal hyperplasia (CAH) based on hormonal testing is successfully implemented in many countries. However, this method cannot detect non-classic CAH and has high false positive rates. Methods This study aimed to develop a novel MALDI-TOF MS assay that can identify common variants and

Autoimmune Thyroid Disease and Female Fertility: Clinical Evidence on Ovarian Reserve, Infertility Treatment Outcomes, and Pathophysiology

open access: yesReproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
Thyroid autoimmunity may exert a subtle influence on ovarian reserve through complex endocrine and immune mechanisms, with age‐specific variation. Although AMH alterations are observed, their clinical relevance for primary ovarian insufficiency, fertility, and treatment outcomes of assisted reproduction remains unclear, highlighting the need for ...

Both positive and negative selection pressures contribute to the polymorphism pattern of the duplicated human CYP21A2 gene. [PDF]

open access: yesPLoS ONE, 2013
The human steroid 21-hydroxylase gene (CYP21A2) participates in cortisol and aldosterone biosynthesis, and resides together with its paralogous (duplicated) pseudogene in a multiallelic copy number variation (CNV), called RCCX CNV.

Detection of mutations in theCYP21A2gene: genotype-phenotype correlation in Slovenian couples with conceiving problems [PDF]

open access: yesBalkan Journal of Medical Genetics, 2015
AbstractThe objective of this study was to compare the CYP 21A2 genetic profiles of couples with unexplained fertility problems (UFP) with genetic profiles of healthy controls (HCs). Furthermore, we analyzed associations between mutations in theCYP21A2gene and various clinical and laboratory parameters.

Genome‐Wide Cross‐Trait Analysis Dissects the Shared Genetic Architecture Between Type 2 Diabetes Mellitus and Metabolic Dysfunction–Associated Steatotic Liver Disease

open access: yesHuman Mutation, Volume 2026, Issue 1, 2026.
The observational studies confirmed the high prevalence of metabolic dysfunction–associated steatotic liver disease (MASLD) in patients with Type 2 diabetes mellitus (T2DM), but whether this reflects a shared genetic etiology and exists underlying causal relationships remains unknown. Here, we utilized the largest scale cross‐trait analysis from genome‐

A Rare Case of Co-occurrence of Multiple Endocrine Neoplasia Syndrome and Congenital Adrenal Hyperplasia

open access: yesОжирение и метаболизм
Multiple endocrine neoplasia type 1 (MEN1) and congenital adrenal hyperplasia (CAH) are rare monogenic hereditary endocrinopathies with a prevalence of 1–9 cases per 100,000 and 9–15 cases per 100,000, respectively.
