Stability analysis of a hypothalamic-pituitary-adrenal axis model with inclusion of glucocorticoid receptor and memory [PDF]

open access: yesAIP Conference Proceedings 1798, 020111, 2017, 2016
This paper analyzes a four-dimensional model of the hypothalamic-pituitary-adrenal (HPA) axis that includes the influence of the glucocorticoid receptor in the pituitary. Due to the spatial separation between the hypothalamus, pituitary and adrenal glands, distributed time delays are introduced in the mathematical model.

Congenital adrenal hyperplasia

open access: yesMedicine, 2013
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder of adrenal steroid biosynthesis affecting 1/10,000 to 1/15,000 live births. The most common form is 21-hydroxylase deficiency due to mutations in the CYP21A2 gene. CAH classically presents at birth with ambiguous genitalia in an affected female.

NonClassic Congenital Adrenal Hyperplasia [PDF]

open access: yesInternational Journal of Pediatric Endocrinology, 2010
Nonclassic congenital adrenal hyperplasia (NCAH) due to P450c21 (21-hydroxylase deficiency) is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias ...
