RCV003625184 | SCV004407658 | uncertain significance | Glycogen storage disease due to glucose-6-phosphatase deficiency type IA | 2022-11-14 | criteria provided, single submitter | clinical testing | This sequence change results in a frameshift in the G6PC gene (p.Val348Serfs*19). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 10 amino acid(s) of the G6PC protein and extend the protein by 8 additional amino acid residues. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with G6PC-related conditions. This variant disrupts the C-terminus of the G6PC protein. Other variant(s) that disrupt this region (p.Gln351*) have been observed in individuals with G6PC-related conditions (PMID: 32313153). This suggests that this may be a clinically significant region of the protein. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
