Labcorp Genetics (formerly Invitae), Labcorp RCV003618376 SCV004411076 pathogenic Pitt-Hopkins syndrome 2022-11-08 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with TCF4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg446Ilefs*15) in the TCF4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TCF4 are known to be pathogenic (PMID: 18728071, 22045651).
