Radioulnar synostosis, radial ray abnormalities, and severe malformations in the male: a new X-linked dominant multiple congenital anomalies syndrome?
We describe a multiple congenital anomalies (MCA) syndrome dominantly transmitted through three generations. Radial ray abnormalities with wide variability of expression were observed in four female patients. Moreover, a 14-week-gestation male fetus had severe radial ray malformation, anencephaly, unilateral renal agenesis, and a common dorsal mesentery. Results of high-resolution karyotyping were normal in the malformed fetus and his affected mother. Furthermore, several spontaneous abortions of male fetuses had occurred in this pedigree. To our knowledge, a similar association has not been described previously. It could represent a new X-linked dominant MCA syndrome, or an autosomal dominant condition with severe expression limited to males.
