Parental consanguinity is present in about 30% of the cases. A large number of cases were reported in Amish population of Lancaster County, Pennsylvania USA and also in Aboriginal community of Australia in 1964. The incidence in Amish population is 1/5000 live births and in general population 7/1,000,000. There are only 150 cases reported worldwide. The principal feature of this syndrome is a tetrad of disproportionate dwarfism, ectodermal dysplasia, bilateral postaxial polydactyly and congenital heart defects.
