Labcorp Genetics (formerly Invitae), Labcorp RCV001053073 SCV001217315 pathogenic Glycogen storage disease, type II 2023-05-15 criteria provided, single submitter clinical testing Disruption of this splice site has been observed in individual(s) with Pompe disease (PMID: 17056254). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. 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. ClinVar contains an entry for this variant (Variation ID: 849168). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 12 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).
