| Invitae | RCV001384693 | SCV001584269 | pathogenic | Glycogen storage disease due to glucose-6-phosphatase deficiency type IA | 2021-08-04 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 2-5 of the G6PC gene. The 5' boundary is likely confined to intron 1. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product. This variant has not been reported in the literature in individuals affected with G6PC-related conditions. This variant disrupts a region of the G6PC protein in which other variant(s) (p.Gln347*) have been determined to be pathogenic (PMID: 7573034, 8182131, 8733042, 10070617, 11949931, 28397058). 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. |
