Labcorp Genetics (formerly Invitae), Labcorp RCV002846713 SCV003222678 pathogenic Mucopolysaccharidosis, MPS-IV-B; GM1 gangliosidosis 2022-07-22 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 GLB1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Thr226Asnfs*3) in the GLB1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GLB1 are known to be pathogenic (PMID: 18524657).
