<unk>  (HMD), or simply<unk>  dysplasia, is a rare autosomal dominant multiepithelial disorder causing systemic maldevelopment of the epithelia and mucous membranes that line the surface of tissues and structures throughout the body, particularly affecting systems affiliated with mucosa, which includes the respiratory, digestive, urinary, reproductive and immune systems. The disorder is attributed to improper formation of desmosomes and gap junctions, which prevents proper cornification of the epithelial layer of the skin.
