Parental consanguinity in two sibs with omodysplasia

Two sibs with omodysplasia were born to phenotypically normal but consanguineous parents. They had severe micromelic dwarfism, facial anomalies, and mental retardation. One had a congenital heart defect. The radiographic findings are typical: hypoplastic distal end of the humerus with radioulnar diastasis. Parental consanguinity and clinical manifestations in 2 sibs suggest autosomal recessive inheritance. © 1994 Wiley-Liss, Inc.
