Labcorp Genetics (formerly Invitae), Labcorp RCV002046393 SCV002317332 likely pathogenic Glycogen storage disease, type II 2021-07-25 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with GAA-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 6 of the GAA gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in GAA are known to be pathogenic (PMID: 18425781, 22252923). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
