Mental retardation associated with congenital heart disease, blepharophimosis, blepharoptosis, and hypoplastic teeth

We report two sisters with mental retardation, congenital heart disease, blepharophimosis, blepharoptosis, and hypoplastic teeth. A female paternal cousin has the same anomalies, but without congenital heart disease. The chromosomes of these patients are normal and the parents are non-consanguineous.
