Familial glucocorticoid deficiency (FGD) is a group of primary adrenal insufficiencies characterized clinically by neonatal hyperpigmentation, hypoglycemia, failure to thrive, and recurrent infections, and biochemically by glucocorticoid deficiency without mineralocorticoid deficiency.
Features include always present findings: Adrenal insufficiency and Decreased circulating cortisol level; and very common findings: Failure to thrive, Hypotension, Generalized hyperpigmentation, and Abnormal circulating adrenocorticotropin concentration and others. 35 total HPO annotations.
