Kaufman oculocerebrofacial syndrome in a girl of 15 years.

Kaufman oculocerebrofacial syndrome (KOS) is a rare autosomal recessive disorder characterized by severe mental retardation, microcephaly, long narrow face, ocular anomalies, and long thin hands and feet. To our knowledge only 8 cases have been reported so far, diagnosed at a mean age of 10 years. We report on a girl who was diagnosed at 15 years. Further phenotypic delineation is needed to improve diagnosis of this syndrome early in life.
