Glucocorticoid deficiency can be caused by inherited genetic disorders that affect the production of cortisol in the adrenal glands, such as familial glucocorticoid deficiency (FGD). [3] FGD is a group of monogenic recessive disorders caused by disease-causing variants in genes involved in cortisol biosynthesis. [4]
Glucocorticoid deficiency 1 is an adrenocortical failure characterized by low levels of plasma cortisol produced by the adrenal gland despite high levels of plasma ACTH. This is an inherited disorder with several different causes which define the type.
The mutations in the MRAP gene caused the congenital disorder familial glucocorticoid deficiency type 2 (FGD-2). FGD-2 is an autosomal recessive disease with early childhood onset of recurrent infections, hypoglycaemia, skin hyperpigmentation, and failure to thrive due to low glucocorticoids levels. If left untreated, it could be fatal.
Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones.The adrenal glands—also referred to as the adrenal cortex—normally secrete glucocorticoids (primarily cortisol), mineralocorticoids (primarily aldosterone), and androgens.
Mutations in this receptor cause familial glucocorticoid deficiency (FGD) type 1, in which patients have high levels of serum ACTH and low levels of cortisol. [19] [20] Mutation of the receptor gene causes 25% of FGD, and mutation on the MRAP gene causes 20% of FGD. Mutations of ACTH can also contribute to this pathology: mutation of the ...
Mutations in the NNT gene have been associated to familial glucocorticoid deficiency 1, a severe autosomal recessive disorder in human characterized by insensitivity to adrenocorticotropic hormone action on the adrenal cortex and an inability of the adrenal cortex to produce cortisol [12] Glucocorticoid deficiency 1 usually presents in neonatal ...

Adrenal insufficiency can be caused by autoimmune disorders such as autoimmune adrenalitis, autoimmune polyglandular syndrome, and lymphocytic hypophysitis, or congenital disorders such as congenital adrenal hyperplasia, adrenoleukodystrophy, familial glucocorticoid deficiency, combined pituitary hormone deficiency, and POMC mutation.
