A kindred with alopecia, keratosis, pilaris, cataracts, and psoriasis

Three members of a family with numerous ectodermal abnormalities are described. These anomalies primarily include patchy alopecia beginning in childhood, premature cataracts, widespread keratosis pilaris, and psoriasis. The alopecia and premature cataracts appear to follow an autosomal dominant inheritance pattern with incomplete penetrance and appear to be linked. Psoriasis also occurs in several members of this family and probably represents a separate but possibly related genodermatosis. This kindred has features of both keratosis follicularis spinulosa decalvans and ichthyosis follicularis, and the disorder seems to fit into the group of follicular hyperkeratosis disorders.
