HistoryThis section has been translated automatically.
Ellis and van Creveld, 1940
DefinitionThis section has been translated automatically.
Very rare autosomal recessive syndrome with dysplasia of the ectoderm and mesoderm descendants: characteristic skeletal dysplasia, heart defects, polydactyly and nail hypoplasia.
EtiopathogenesisThis section has been translated automatically.
Autosomal recessive hereditary disease caused by mutations of the Ellis-van Creveld Syndrome genes 1 and 2 (EVC 1 gene; EVC gene 2; gene locus: 4p16).
Clinical featuresThis section has been translated automatically.
- Polydactyly, occasionally syndactyly in the lower extremities.
- Malformed fingernails: Nail plate often only intimated, also anonymity.
- Small or dwarf growth as in chondrodystrophy: shortening of the long tubular bones, deformation of the distal and proximal epiphyses.
- Microcele, limited to the middle part of the upper lip.
- Absence of the upper external incisors.
- Also: multiple exostoses, congenital heart defects, sexual infantilism.
- Optional: alopecia.
