kinky hair disease (redirected from Trichopoliodystrophy)
kink·y-hair dis·ease , kinky hair disease [MIM*309400]
an inborn error of copper metabolism, onset within a few weeks of birth; manifested by short, sparse, poorly pigmented kinky hair; failure to thrive; development of seizures; spasticity; and progressive mental deterioration leading to death. X-linked recessive inheritance due to a defect of copper transport, caused by mutation in the Menkes gene (MNK), which encodes a copper-transporting ATPase on Xq.
kinky hair disease
Etymology: Du, kink, short twist + AS, haer + L, dis + Fr, aise, ease
An X-linked recessive [MIM309400] condition caused by defective copper metabolism with copper accumulation in certain tissues—e.g., fibroblasts, kidneys, gastrointestinal mucosa—and a relative deficiency of copper in other tissues—e.g., brain and liver—accompanied by defective copper enzymes—e.g., lysyl oxidase, tyrosinase
an inherited condition characterized by short, sparse, poorly pigmented hair with shafts that are twisted and broken. Other mental and physical disorders are usually associated with the disease.
Prognosis Death often occurs in early infancy with progressive neurologic and vascular degeneration; kinky hair also occurs in autosomal dominant trichodento-osseous syndrome and in normal people
