New syndrome: autosomal dominant microcephaly and radio-ulnar synostosis

Pierre Robin Sequence with Esophageal Atresia and Congenital Radioulnar Synostosis

A wide spectrum of anomalies can be associated with Pierre Robin sequence. This report presents a 3-day-old infant with micrognathia, U-shaped cleft palate, low-set right ear with microtia, glossoptosis, esophageal atresia, and right congenital radioulnar synostosis. The association of congenital radioulnar synostosis and esophageal atresia with Pierre Robin sequence has not been previously described.

Additional case of Tsukahara's syndrome or new syndrome: Further delineation of the association of microcephaly and radio-ulnar synostosis

In 1994, Giuffré et al. reported two unrelated families in which some of the members had microcephaly and radio-ulnar synostosis, suggesting a new condition. Since this first report, Tsukahara et al. and Udler et al. described two distinct patients with a different condition characterized by radio-ulnar synostosis, short stature, microcephaly, scoliosis, and mental retardation. Here we report on a new case of microcephaly and radio-ulnar synostosis and discuss the possible relationship between Tsukahara's syndrome and the phenotype described by Giuffré et al.

Radio-ulnar synostosis, short stature, microcephaly, scoliosis, and mental retardation

We report on a 9-year-old boy with radio-ulnar synostosis, short stature, microcephaly, scoliosis, and mental retardation. We propose that he has a new syndrome.
