Primary pigmented nodular adrenocortical disease (PPNAD) is a form of ACTH-independent adrenal hyperplasia resulting in Cushing syndrome. It is usually seen as a manifestation of the Carney complex (CNC1; 160980), a multiple neoplasia syndrome. However, PPNAD can also occur in isolation (Groussin et al., 2002). Genetic Heterogeneity of Primary Pigmented Nodular Adrenocortical Disease See also PPNAD2 (610475), caused by mutation in the PDE11A gene (604961) on chromosome 2q31; PPNAD3 (614190), caused by mutation in the PDE8B gene (603390) on chromosome 5q13; and PPNAD4 (615830), caused by a duplication on chromosome 19p13 that includes the PRKACA gene (601639). [from OMIM]

Cushing syndrome is a clinical designation for the systemic signs and symptoms arising from excess cortisol production. Affected individuals typically show hypertension, impaired glucose tolerance, central obesity, osteoporosis, and sometimes depression. Corticotropin-independent Cushing syndrome results from autonomous cortisol production by the adrenal glands, often associated with adrenocortical tumors. Adrenocortical tumors are most common in adult females (summary by Cao et al., 2014; Sato et al., 2014). [from OMIM]
