Glucocorticoid Deficiency 1, also known as acth resistance, is related to familial glucocorticoid deficiency and noonan syndrome 1. An important gene associated with Glucocorticoid Deficiency 1 is MC2R (Melanocortin 2 Receptor), and among its related pathways/superpathways are Signal Transduction and GPCR downstream signalling. Affiliated tissues include adrenal cortex and adrenal gland, and related phenotypes are generalized hyperpigmentation and recurrent hypoglycemia
