[Identification of a Tp63 gene variant in an abortus with Ectrodactyly, Ectodermal dysplasia, Cleft lip/palate syndrome by whole-exome sequencing].

To detect potential variant in a male fetus suspected for Ectrodactyly, Ectodermal dysplasia, Cleft lip/palate (EEC) syndrome.Peripheral blood samples of the fetus and his parents were collected for the extraction of DNA. Whole-exome sequencing was carried out to detect potential variants. Suspected variants were verified by Sanger sequencing.The fetus was found to carry a heterozygous c.673C>T missense variant of the Tp63 gene, which was known to underlie split-hand/split-foot malformation. The same variant was not found in either parents.The heterozygous c.673C>T missense variant of the Tp63 gene probably underlies the EEC syndrome in the fetus. Above finding also expanded the phenotypic spectrum for this variant.
