GAPO syndrome: a new case.

The fifteenth known case of GAPO syndrome is presented: a probable autosomal-recessive condition of growth retardation, alopecia, pseudoanodontia (failure of tooth eruption), and optic atrophy. This article contains the clinical report of a 9-year-old girl and a short review of the hitherto-known cases. The syndrome could be attributed to either ectodermal dysplasia or perhaps an accumulation of extracellular connective tissue matrix.
