Cross-species summary: Hyperadrenocorticism (or Cushing syndrome) refers to genetic and iatrogenic hypersecretion of adrenocorticotropic hormone (ACTH) (e.g. caused by tumours of either the pituitary or adrenal glands; or long-term administration of exogenous glucocorticoids). Entries for Cushing disease (pituitary-dependent hyperadrenocorticism) are included here and for some species also under the OMIA phene Cushing disease (OMIA:000247)

Species-specific name: Also know as Pituitary Pars Intermedia Dysfunction or Cushing disease

Species-specific symbol: PPID

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
