GeneDx RCV000081312 SCV000491226 pathogenic not provided 2016-09-26 criteria provided, single submitter clinical testing The W798R variant in the PYGM gene has been reported previously, sometimes with alternate nomenclature of W797R, in the homozygous state, as well as the heterozygous state with a second variant of unknown phase, in multiple unrelated individuals with McArdle disease (Rubio et al., 2000; Fernandez et al., 2000; Martin et al., 2001; Rubio et al., 2007; Garcia-Consuegra, et al., 2009). The W798R variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The W798R variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In addition, this substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret W798R as a pathogenic variant.

SIB Swiss Institute of Bioinformatics RCV000002402 SCV000803466 likely pathogenic Glycogen storage disease, type V 2018-05-31 criteria provided, single submitter curation This variant is interpreted as a Likely Pathogenic, for Glycogen storage disease 5, in Autosomal Recessive manner. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS4-Moderate => Common mutation observed in multiple unrelated patients. (PMID:10590419,29143597,/10681080,14722619). PM3 => For recessive disorders, detected in trans with a pathogenic variant (PMID:29143597). PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product.
