Labcorp Genetics (formerly Invitae), Labcorp RCV003111174 SCV003793192 pathogenic Mucopolysaccharidosis, MPS-IV-B; GM1 gangliosidosis 2023-12-26 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exon(s) 2-5 of the GLB1 gene. This variant would be expected to be in-frame, preserving the integrity of the reading frame. This variant has not been reported in the literature in individuals affected with GLB1-related conditions. This variant disrupts a region of the GLB1 protein in which other variant(s) (p.Leu155Arg) have been determined to be pathogenic (PMID: 17309651, 19472408, 20175788, 25557439). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
