MENKES DISEASE

By Gary M. White, MD


Menkes Disease (MD) is a lethal X-linked disorder of copper metabolism with many features including abnormal hair, epilepsy and early death.

Clinical

The hair is almost always hypopigmented at presentation. It is often short and fragile. By 1-2 years of age, it may become coarse and twisted (kinky hair). Pili torti may be found.

The classic presentation is global developmental delay and refractory seizures in the infant 3 months of age or less. Mental and physical retardation and death may occur before 3 years of age. Low serum copper and ceruloplasmin are found.

Differential Diagnosis

See fragile hair.

Treatment

Anti-convulsant treatment should be provided. The prognosis is poor with eventual death within the first few years of life. Early initiation of copper therapy as well as the potential for gene therapy may provide some hope.
