Description

This sequence change creates a premature translational stop signal (p.Pro79Thrfs*38) in the EPHB4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EPHB4 are known to be pathogenic (PMID: 28687708). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with EPHB4-related conditions. ClinVar contains an entry for this variant (Variation ID: 1383632). For these reasons, this variant has been classified as Pathogenic.
