Váradi syndrome (OFD VI) or opitz trigonocephaly syndrome: Overlapping manifestations in two cousins

Abstract

We report on 2 cousins, offspring of consanguineous matings, with multiple congenital anomalies. Square face, frontal bossing with metopic ridge, small anteverted nose, flat nasal bridge, slanted palpebral fissures, and epicanthal folds contributed to an unusual appearance. Multiple bucco-alveolar frenula and notched inferior alveolar ridges were present at birth and one had a notched uvula and submucous cleft of the hard palate. Both had congenital heart anomalies, micropenis, and cryptorchidism. Persistence of Müllerian structures was documented at necropsy in one patient. The surviving patient was mentally retarded and had unilateral central hexadactyly and partial agenesis of the corpus callosum. Bulimia and episodic hyperthermia were attributed to hypothalamic dysfunction. Results of unstimulated endocrine studies and gonadotropin releasing hormone (GnRH), and human chorionic gonadotropin (HCG) stimulation tests were normal. The manifestations of the 2 patients overlap those reported in the OFD VI and Opitz trigonocephaly syndromes.
