Woolly hair--study of a family.

A white English family is described with autosomal dominant woolly wiry hair. The propositus had woolly curly scalp hair, congenital perceptive deafness and dominant ichthyosis vulgaris. Her brother was epileptic and also deaf, but his skin and hair were normal and a male first cousin had dominant ichthyosis vulgaris but normal hair and hearing. Consanguinity was an interesting additional feature in this family.
