ClinGen Lysosomal Storage Disorder Variant Curation Expert Panel, ClinGen RCV000169616 SCV001371695 benign Glycogen storage disease, type II 2020-01-22 reviewed by expert panel curation The highest continental population minor allele frequency for c.668G>A (p.Arg223His) in gnomAD v2.1.1 is 0.74034 in the European non-Finnish population. This is higher than the ClinGen LSD VCEP's BA1 threshold (>0.01), therefore meeting the BA1 criterion. There is a ClinVar entry for this variant (Variation ID: 92488; 2 star review status) with six submitters classifying the variant as benign, and one as likely benign. In summary, this variant meets the criteria to be classified as benign for Pompe disease. GAA-specific ACMG/AMP criteria applied, as specified by the ClinGen LSD VCEP: BA1.

Illumina Clinical Services Laboratory,Illumina RCV000169616 SCV000407267 benign Glycogen storage disease, type II 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.
