ClinGen Lysosomal Storage Disorder Variant Curation Expert Panel	RCV000399277	SCV001371711	benign	Glycogen storage disease, type II	2020-01-23	reviewed by expert panel	curation	The highest continental population minor allele frequency for c.2553G>A (p.Gly851=) in gnomAD v2.1.1 is 0.63818 in the European non-Finnish population. Note that the minor allele frequency is even higher in the Ashkenazi Jewish (0.70216) and European Finnish (0.64436) populations. These allele frequencies are higher than the ClinGen LSD VCEP's BA1 threshold (>0.01), meeting this criterion. There is a ClinVar entry for this variant (Variation ID: 92481, two star review status), with 6 submitters classifying the variant as 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 Laboratory Services, Illumina	RCV000399277	SCV000407302	benign	Glycogen storage disease, type II	2018-01-12	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.

Ambry Genetics	RCV002453396	SCV002740155	benign	Cardiovascular phenotype	2015-12-22	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: 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.
