Labcorp Genetics (formerly Invitae), Labcorp RCV003808423 SCV004591080 pathogenic Mucopolysaccharidosis, MPS-III-C; Retinitis pigmentosa 73 2023-02-25 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 HGSNAT-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Pro25Argfs*35) in the HGSNAT gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in HGSNAT are known to be pathogenic (PMID: 17033958, 19479962).
