Six cases of congenital peripheral facial diplegia occurring in three generations are reported. The action of an autosomal dominant gene is suggested. In the same family were observed other congenital anomalies (strabismus, nistagmus). One of the patients with facial palsy had also micrognathy. Patients with other congenital anomalies but without facial palsy were examined not adequately; therefore it was impossible to correlate these findings with those concerning the facial palsy.
