Ellis-van Creveld syndrome in a fetus with rhizomelia and polydactyly. Report of a case diagnosed by genetic analysis, and correlation with pathological andradiologic findings

Ellis-van Creveld syndrome is an autosomal recessive disorder mainly characterized by a disproportionate limb dwarfism, chondroectodermal dysplasia, congenital heart disease, postaxial polydactyly, and dysplastic fingernails and teeth. Only 300 cases have been published worldwide. We report a 21-wee...

description Ellis-van Creveld syndrome is an autosomal recessive disorder mainly characterized by a disproportionate limb dwarfism, chondroectodermal dysplasia, congenital heart disease, postaxial polydactyly, and dysplastic fingernails and teeth. Only 300 cases have been published worldwide. We report a 21-week fetus with rhizomelia and polydactyly detected. Gross photographs, radiologic studies and pathological study were performed leading to the clinico-pathological suspicion of EvC. DNA from fresh fetal tissue was extracted for sequencing the EVC and EVC2 genes. p.W215X and p.R677X mutations were identified in the EVC2 gene in the fetal sample. Parental sample analysis showed the p.W215X mutation to be inherited from the mother and the p.R677X mutation from the father. The clinical information is essential not only to arrive at a correct diagnosis in fetuses with pathologic ultrasound findings, but also to offer a proper genetic counseling to the parents and their relatives. ► EvC syndrome: characterized by chondroectodermal dysplasia and postaxial polydactyly. ► Only 300 cases of EvC syndrome have been reported worldwide. ► This condition has been found to be associated with EVC and EVC2 mutations. ► All the clinical information is essential to arrive at a correct diagnosis in fetuses.
