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.
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 ]
Individuals who have generalized glucocorticoid resistance may exhibit biochemical hypercortisolism in the absence of Cushing's syndrome symptoms. [6] The condition's clinical phenotype varies from cases with no symptoms to signs of excess mineralocorticoids in the body such as hypokalemic alkalosis and hypertension and/or androgen excess, including oligospermia in males, menstrual ...
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.
The glucocorticoids provide a reliable substitute for cortisol, thereby reducing ACTH levels. Reducing ACTH also reduces the stimulus for continued hyperplasia and overproduction of androgens. In other words, glucocorticoid replacement is the primary method of reducing the excessive adrenal androgen production in both sexes.
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 ...
The dose ratio r is the ratio of the dose of agonist required for half maximal response with the antagonist present divided by the agonist required for half maximal response without antagonist ("control"). In other words, the ratio of the EC50s of the inhibited and un-inhibited curves. Thus, r represents both the strength of an antagonist and ...
Dose–response relationships can be described by dose–response curves. This is explained further in the following sections. This is explained further in the following sections. A stimulus response function or stimulus response curve is defined more broadly as the response from any type of stimulus, not limited to chemicals.
