Background: Primary generalised glucocorticoid resistance (PGGR) is a rare condition characterised by tissue insensitivity to glucocorticoids owing to inactivating mutations of the hGR gene. A new case of PGGR was reported in a patient with an adrenal incidentaloma harboring a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 of the receptor.Objec...
