Pfeiffer type cardiocranial syndrome: a third case report

Pfeiffer-type cardiocranial syndrome is a rare condition reported previously in three patients, two of whom were sibs. All three patients shared features that included growth and developmental retardation, sagittal synostosis, hypertelorism, low set ears, micrognathia with mandibular ankylosis, congenital heart defects, and genital anomalies. The purposes of this report are to present a fourth patient with features of the Pfeiffer-type cardiocranial syndrome, to expand the clinical phenotype of this condition, and to present evidence that supports the concept that this phenotype represents a distinct nosological entity.
