<unk>  (MNK), also known as<unk>  syndrome, is an X-linked recessive disorder caused by mutations in genes coding for the copper-transport protein ATP7A, leading to copper deficiency. Characteristic findings include kinky hair, growth failure, and nervous system deterioration. Like all X-linked recessive conditions,<unk>  is more common in males than in females. The disorder was first described by John Hans<unk>  in 1962. Onset occurs during infancy, with incidence of about 1 in 100,000 to 250,000 newborns; affected infants often do not live past the age of three years, though there are rare cases in which less severe symptoms emerge later in childhood.
