Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000409554 SCV001338431 pathogenic Glycogen storage disease type III 2020-04-24 criteria provided, single submitter clinical testing Variant summary: AGL c.276delG (p.Gln92HisfsX16) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 8e-06 in 250684 control chromosomes (gnomAD). c.276delG has been reported in the literature in individuals affected with Glycogen Storage Disease Type III (Lucchiari_2002, Crushell_2010). These data indicate that the variant may be associated with disease. At least one publication reports this variant results in <10% of normal AGL activity (Crushell_2010). One ClinVar submitter (evaluation after 2014) cites the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
