" /> Glucocorticoid deficiency 4 with or without mineralocorticoid deficiency - CISMeF





Preferred Label : Glucocorticoid deficiency 4 with or without mineralocorticoid deficiency;

Symbol : GCCD4;

CISMeF acronym : GCCD4;

Type : Phenotype, molecular basis known;

Description : Familial glucocorticoid deficiency is a rare autosomal recessive disorder characterized by an inability of the adrenal cortex to produce cortisol in response to stimulation by adrenocorticotropic hormone (ACTH). Affected individuals typically present within the first few months of life with symptoms related to cortisol deficiency, including failure to thrive, recurrent illnesses or infections, hypoglycemia, convulsions, and shock. The disease is life-threatening if untreated (summary by Meimaridou et al., 2012). For a discussion of genetic heterogeneity of familial glucocorticoid deficiency, see GCCD1 (202200).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the nicotinamide nucleotide transhydrogenase gene (NNT, 607878.0001);

Laboratory abnormalities : Low cortisol level; Unresponsive to ACTH stimulation; Elevated ACTH; Elevated renin level; Hyperkalemia; Hyponatremia; Natriuria, inappropriate; Low aldosterone level;

Prefixed ID : #614736;
