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.

The complexities in genotyping of congenital adrenal hyperplasia: 21-hydroxylase deficiency [PDF]

open access: yes, 2019
The deficiency of 21-hydroxylase due to CYP21A2 pathogenic variants is a rather frequent disease with serious consequences, going from a real mortality risk to infertility and to milder symptoms, nevertheless important for affecting the patients’ self ...

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.

Expanded carrier screening for inherited genetic disease using exome and genome sequencing

open access: yesJournal of Genetic Counseling, Volume 34, Issue 2, April 2025.
Abstract The goal of this study was to assess the feasibility of using exome (ES) and genome sequencing (GS) in guiding preconception genetic screening (PCGS) for couples who are planning to conceive by creating a workflow for identifying risk alleles for autosomal recessive (AR) and X‐linked (XL) disorders without the constraints of a predetermined ...

Suboptimal psychosocial outcomes in patients with congenital adrenal hyperplasia : epidemiological studies in a nonbiased national cohort in Sweden [PDF]

open access: yes, 2014
Context: Congenital adrenal hyperplasia (CAH), CYP21A2 deficiency, results in cortisol and aldosterone deficiency and increased production of androgens, with a good genotype phenotype correlation.

Immunometabolism of Liver Xenotransplantation and Prospective Solutions

open access: yesAdvanced Science, Volume 12, Issue 9, March 6, 2025.
After xenotransplantation, pig livers will replace those of human patients to maintain the stability of metabolism and immune system. The incompatibility of immunometabolism between humans and pigs induces rejection, inflammation, coagulation dysfunction, and liver failure. The profile of immunometabolism pre‐transplantation and post‐transplantation is

Estudo de variações de sequência do promotor do gene CYP21A2 em pacientes com suspeita de hiperplasia supra-renal congénita [PDF]

open access: yes, 2015
Mestrado em Bioquímica - Métodos BiomolecularesA Hiperplasia Supra-Renal Congénita (HSRC), causada por deficiência na enzima 21-hidroxilase, constitui uma das doenças autossómicas recessivas mais frequentes.

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 ...

CYP21A2 Gene Expression in a Humanized 21-Hydroxylase Mouse Model Does Not Affect Adrenocortical Morphology and Function

open access: yesJournal of the Endocrine Society, 2022
Steroid 21-hydroxylase is an enzyme of the steroid pathway that is involved in the biosynthesis of cortisol and aldosterone by hydroxylation of 17α-hydroxyprogesterone and progesterone at the C21 position.
