Ellis van Creveld syndrome (chondroectodermal dysplasia, MIM 22550) in three siblings from a non-consanguineous mating.
The major diagnostic features of Ellis van Creveld syndrome (EvC) includes disproportionate short stature, polydactyly, ectodermal anomalies, and structural heart defects. We describe three siblings with EvC of a non-consanguineous mating. The history of these siblings well illustrate the clinical manifestations and complications that children with EvC encounter. All three girls had short stature, narrow rib cage, polydactyly and nail hypoplasia. The first daughter died in early infancy in respiratory failure. The second daughter underwent open heart surgery for atrial septal defect repair. The third daughter, diagnosed in utero with fetal ultrasonography, currently is scheduled for surgical excision of extra-digits and extraction of neonatal teeth. Infant mortality rates among patients with EvC is strikingly high due primarily to cardiorespiratory failure. If they survive infancy morbidity is significant. The gene effected in individuals with EvC has recently been identified on the short arm of chromosome 4. Future testing for gene mutations may provide valuable information for premarital counseling and prenatal diagnosis. Three offspring with disproportionate short stature, polydactyly, and ectodermal dysplasia of a non-consanguineous mating, strongly indicate parental heterozygosity for Ellis van Creveld syndrome.
