MOLECULAR PATHOLOGY OF 21-HYDROXYLASE DEFICIENCY [PDF]

open access: yesPediatric Research, 1993
Pathological mutations in steroid 21-hydroxylase deficiency appear to derive exclusively from sequence exchange between the 21-hydroxylase gene (CYP21B) and a closely related pseudogene (CYP21A), located 30 kb telomeric to CYP21B and functionally inactive because of several mutations distributed along its length.

Relationships of Basal Level of Serum 17-Hydroxyprogesterone with that of Serum Androstenedione and Their Stimulated Responses to a Low Dose of ACTH in Young Adult Patients with Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency [PDF]

open access: yes, 2011
A single measurement of serum 17α-hydroxyprogesterone (17OHP) level can be unreliable because of its marked diurnal variation. We investigated the relationship of serum level of 17OHP with that of androstenedione (AD), which shows a smaller diurnal ...

Location of the gene for 21-hydroxylase deficiency [PDF]

open access: yesPediatric Research, 1979
We have studied 34 families in whom the propositus had CAH and confirm the original observation (1) that the gene responsible is closely related to the HLA loci. In one family the paternal HLA antigens were A1 B8, B37, DRW5 and the maternal antigens A3, A9, CW3, CW5 B12, B40, DRW1, DRW5.

Murine Models and Human Cell Line Models to Study Altered Dynamics of Ovarian Follicles in Polycystic Ovary Syndrome

open access: yesAdvanced Biology, EarlyView.
The manuscript examines preclinical murine and human models to study polycystic ovary syndrome (PCOS), delving into the cellular and molecular mechanisms underlying altered ovarian follicular dynamics. It explores the cellular interactions involved in normal and PCOS ovaries and outlines the current and novel strategies in the search for preclinical ...

An XX male with 21-hydroxylase deficiency [PDF]

open access: yesPediatric Research, 1981
The patient is the second child of healthy unrelated parents,his older brother is normal. At birth the genitalia were ambiguous; the phallus was adequate in size but there was chordee and perineal hypospadias. The labio-scrotal folds were fused. Gonads were palpable in both groins. The karyotype (blood and skin) was normal female XX.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

open access: yesAdvanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...
