Illumina Laboratory Services, Illumina RCV001079385 SCV001287879 uncertain significance Glycogen storage disease, type II 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard RCV001079385 SCV001423081 uncertain significance Glycogen storage disease, type II 2020-01-22 criteria provided, single submitter curation The c.1920T>G (p.Pro640=) variant in GAA has not been reported in individuals with Glycogen Storage Disease II but has been reported in 2 European individuals with unexplained limb-girdle muscle weakness (PMID: 29149851). This variant has also been reported likely benign (by GeneDx, PreventionGenetics, Mayo Clinic Genetic Testing Laboratories, and Invitae) and as a VUS by EGL in ClinVar (Variation ID: 255358). This variant has been identified in 0.09150% (18/19672) of East Asian chromosomes, 0.04553% (11/24162) of European (Finnish) chromosomes, and 0.01683% (21/124752) of European (non-Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs144090460). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. Computational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. However, novel synonymous variants supported by computational evidence without raised suspicion for an impact are likely benign (Richards 2015). In summary, although additional studies are required to fully establish its clinical significance, this variant is likely benign. ACMG/AMP Criteria applied: PM2, BP4, BP7 (Richards 2015).

Ambry Genetics RCV002411111 SCV002719778 likely benign Cardiovascular phenotype 2022-08-03 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
