Atrioventricular block and wiry hair in Teebi hypertelorism syndrome.
We report on a 4 1/2-year-old girl with clinical features of Teebi hypertelorism syndrome (THS), including a prominent forehead with a widow's peak, heavy and broad eyebrows, hypertelorism, long palpebral fissures, ptosis, a thin upper lip, a grooved chin, and a left preauricular cyst. She required a pacemaker for third degree atrioventricular (AV) block, a finding that has not been previously reported in 36 other patients with THS and for which we were unable to identify other causes. We have reviewed the previous reports of THS and note a characteristic facial appearance with hypertelorism, heavy, broad, and arched eyebrows, a thin upper lip with a long and deep philtrum, and a prominent forehead. Structural cardiac defects were present in five patients, implying that cardiac investigations are warranted in patients with a cardiac murmur and a clinical diagnosis of THS.
