Labcorp Genetics (formerly Invitae), Labcorp RCV001941982 SCV002229463 pathogenic Multiple congenital exostosis 2024-04-23 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ala560Argfs*5) in the EXT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EXT1 are known to be pathogenic (PMID: 10679937, 11391482, 19810120). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with EXT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1454658). For these reasons, this variant has been classified as Pathogenic.
