Atypical Menkes steely hair disease

Abstract
Menkes steely hair disease (MSHD) is a rare disorder which typically results in severe mental retardation and death in early childhood. A 21‐month‐old boy with an atypical milder form was presented by Procopis et al. [1981]. A second child with the atypical form is presented here who has survived to age 9 years and is doing well clinically.
