Molecules located on the surface or within target cells to which hormones bind. When such receptors are absent or defective, the hormones are without effect. Examples of genetic diseases caused by mutations of genes that encode hormone receptors are androgen-insensitivity syndrome (q.v.) and vitamin D-resistant rickets (q.v.). See androgen receptor, steroid receptor, vitamin D receptor.
