Labcorp Genetics (formerly Invitae), Labcorp RCV003779121 SCV004592194 pathogenic Niemann-Pick disease, type B; Niemann-Pick disease, type A 2023-02-11 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Val200Serfs*57) in the SMPD1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SMPD1 are known to be pathogenic (PMID: 12369017, 15221801). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SMPD1-related conditions. For these reasons, this variant has been classified as Pathogenic.
