Labcorp Genetics (formerly Invitae), Labcorp RCV001699180 SCV003443015 pathogenic not provided 2023-10-17 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg66*) in the GNPTG gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GNPTG are known to be pathogenic (PMID: 19370764, 20301784). This variant is present in population databases (rs193302848, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with mucolipidosis type III gamma (PMID: 15060128, 28950892). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 21713). For these reasons, this variant has been classified as Pathogenic.
