Predicting Residual 21‐Hydroxylase Enzymatic Activity in Pediatric and Adult Congenital Adrenal Hyperplasia Patients: Towards Individualized Therapy

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 11, Page 1869-1881, November 2025.
ABSTRACT Congenital adrenal hyperplasia (CAH) is a genetic disorder characterized by impaired cortisol production and consequent elevated adrenocorticotropic hormone (ACTH): CAH patients often require lifelong hydrocortisone therapy. Disease severity reflects residual 21‐hydroxylase enzyme activity, crucial for cortisol synthesis.

The prevalence and genotype of 21-hydroxylase deficiency in the Croatian Romani population

open access: yesFrontiers in Endocrinology, 2023
ObjectiveCongenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency (21-OHD) is a rare autosomal recessive disorder caused by pathological variants in the CYP21A2 gene.

A Transcriptome‐Wide Association Study Identifies Candidate Susceptibility Loci and Genes for Lung Cancer Risk

open access: yesCancer Medicine, Volume 14, Issue 20, October 2025.
A transcriptome‐wide association study identified 40 genes associated with the risk of lung cancer, leveraging gene expression and genotype data from the Genotype‐Tissue Expression (GTEx) project and summary statistics of a genome‐wide association study on lung cancer.

Society for Endocrinology Clinical Practice Guideline for the Evaluation of Androgen Excess in Women

open access: yesClinical Endocrinology, Volume 103, Issue 4, Page 540-566, October 2025.
ABSTRACT Context Androgen excess is common in women and refers to clinical or biochemical evidence of elevated androgenic steroids such as testosterone. It is associated with underlying polycystic ovary syndrome in the majority of cases. However severe androgen excess is less common and may indicate the presence of underlying adrenal or ovarian ...

Congenital Adrenal Hyperplasia – A Comprehensive Review of Genetic Studies on 21-Hydroxylase Deficiency from India

open access: yesIndian Journal of Endocrinology and Metabolism
Congenital adrenal hyperplasia (CAH) comprises a heterogeneous group of autosomal recessive disorders impairing adrenal steroidogenesis. Most cases are caused by mutations in the CYP21A2 gene resulting in 21-hydroxylase (21-OH) deficiency (21-OHD).

Genetic Loci Associated With Periodontitis: The FinnGen Study Based on National Health Registers

open access: yesJournal of Clinical Periodontology, Volume 52, Issue 9, Page 1263-1275, September 2025.
ABSTRACT Aim To perform a genome‐wide association study (GWAS) for periodontitis in the FinnGen cohort, as genetic factors contribute to periodontitis. Materials and Methods We included nearly 250,000 Finnish individuals who had visited a dentist in the public healthcare sector for a clinical oral examination. We designed three periodontitis phenotypes

CYP21A2 gene mutationsin the women with recurrent miscarriage

open access: yesJournal of obstetrics and women's diseases, 2012
Miscarriage is one of the major problems of modern reproduction. Total frequency of micarrieges is estimated as 15–27 % of total pregnancies. Recurrent Miscarriage (RM) (three or more spontaneous abortions) is responsible for almost 20 % of total miscarrieges. The population frequency of RM fluctuates from 2 % to 5 %.

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

CYP21A2 mutations in pediatric patients with congenital adrenal hyperplasia in Costa Rica

open access: yesMolecular Genetics and Metabolism Reports, 2021
Steroid 21-hydroxylase deficiency accounts for 95% of congenital adrenal hyperplasia (CAH) cases. Newborn screening has allowed for early detection of the disease, and currently, molecular analysis can identify the genotypes of these patients. Phenotype-genotype correlation has been well described in previous studies.

Corticosteroid Biosynthesis Revisited: No Direct Hydroxylation of Pregnenolone by Steroid 21-Hydroxylase

open access: yesFrontiers in Endocrinology, 2021
Cytochrome P450s (CYPs) are an essential family of enzymes in the human body. They play a crucial role in metabolism, especially in human steroid biosynthesis. Reactions catalyzed by these enzymes are highly stereo- and regio-specific.
