Labcorp Genetics (formerly Invitae), Labcorp RCV003064493 SCV003442416 pathogenic Glycogen storage disease, type II 2022-08-23 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln352*) in the GAA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GAA are known to be pathogenic (PMID: 18425781, 22252923). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This premature translational stop signal has been observed in individual(s) with a positive newborn screening result for GAA-related disease (PMID: 24513544).
