Mild facial dysmorphism and quasidominant inheritance in Cenani-Lenz syndrome.

Cenani-Lenz syndrome (CLS; MIM 212780) is a rare autosomal recessive syndactyly/synostosis syndrome. No facial dysmorphism was previously noted. We studied two families; in the first an affected female had a previously affected brother and her father was said to have been similarly affected. Extensive inbreeding in this family suggests quasidominant inheritance. In the second family there was a history of a similarly affected sib who, in addition, had genital anomalies and cleft palate. The parents were first cousins. Both probands had similar mild facial dysmorphism; a high broad, prominent forehead, hypertelorism, a depressed nasal bridge, downslanting palpebral fissures, a short nose, a short prominent philtrum and malar hypoplasia. The present report suggests mild facial dysmorphism and quasidominant inheritance in one family with Cenani-Lenz syndrome.
