Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard RCV001249047 SCV001422992 likely pathogenic Glycogen storage disease, type II 2020-01-15 criteria provided, single submitter curation The p.His612Gln variant in GAA has been reported in at least one Italian individual with glycogen storage disease II (PMID: 16917947, 17915575) and has been identified in 0.007% (1/15326) of African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs768397968). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. In vitro functional studies using cells transfected with the variant provide some evidence that the p.His612Gln variant may impact protein function (PMID: 16917947, 17915575). However, these types of assays may not accurately represent biological function. Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. This variant was reported in combination with reported pathogenic variant c.-32-13T>G and in an individual with glycogen storage disease II (VariationID: 4027, PMID: 16917947). In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic. ACMG/AMP Criteria applied: PS3, PM2, PP3 (Richards 2015).
