Ambry Genetics RCV002426487 SCV002741448 benign Cardiovascular phenotype 2015-12-28 criteria provided, single submitter clinical testing This alteration is classified as 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.
GeneDx RCV000078177 SCV001894237 benign not provided 2018-01-04 criteria provided, single submitter clinical testing Associated with pseudodeficiency of alpha-glucosidase enzyme. Homozygosity for D91N or compound heterozygosity for D91N and a pathogenic variant results in low enzyme activity but no clinical symptoms of Pompe disease (Martiniuk et al., 1990; Tajima et al., 2007; Kroos et al., 2008); This variant is associated with the following publications: (PMID: 31301153, 29181627, 25998610, 20080426, 2203258)

Illumina Laboratory Services, Illumina RCV000531082 SCV001287673 likely 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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Stanford Center for Inherited Cardiovascular Disease, Stanford University RCV000078177 SCV000925080 benign not provided 2017-06-02 no assertion criteria provided provider interpretation The GAA gene is associated with Pompe disease; however, this variant is not associated with disease. It is known to interfere with assays for GAA enzyme activity and is therefore called a "pseudodeficiency allele". Even individuals with two copies of this variant do not have Pompe disease.
