摘要

Ellis-van Creveid syndrome (EvC5 chondroectodermal dyspla-sia; OMIM 225500) is an autosomal recessive skeletal dysplasia with associated multisystem involvement. The syndrome is characterized by short limbs, short ribs, postaxial polydactyly, dysplastic nails, and abnormal teeth. Congenital heart defects occur in 50-60% of cases. In this study, we report EvC in a 6-year-old Chinese girl with hypodontia and polydactyly, mild short stature, and abnormalities of the knee joints. No signs of short ribs, narrow thorax, or congenital heart defects were found in this patient. The EvC phenotype shares some similarity with Weyers acrofacial dysostosis (Weyer; OMIM 193530), an auto-somal dominant disorder clinicaEy characterized by mild short stature, postaxial polydactyly, nail dystrophy, and dysplastic teeth.
