Description

Loss-of-function variants in PCDH19 are known to be pathogenic (PMID: 21053371). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals with PCDH19-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu473Cysfs*48) in the PCDH19 gene. It is expected to result in an absent or disrupted protein product.
