abstract: An autosomal recessive disorder characterized by lamellar ichthyosis, an usual structural defect of the scalp hairs and amino aciduria occurred in two siblings in a South Indian family in Madras. In addition the female sibling was physically and mentally retarded. The disorder differs from typical Netherton's syndrome in several ways.
