Ellis-van Creveld syndrome

Ellis–Van Creveld syndrome (also called mesoectodermal dysplasia but see 'Nomenclature' section below) is a rare genetic disorder of the skeletal dysplasia type. Signs and symptoms It involves numerous anomalies including: Post-axial polydactyly Congenital heart defects (most commonly an atrial septal defect producing a common atrium, occurring in 60% of affected individuals) Teeth present at birth (natal teeth) Fingernail dysplasia Short-limbed dwarfism, mesomelic pattern Short ribs Cleft palate Malformation of the wrist bones (fusion of the hamate and capitate bones).
