Labcorp Genetics (formerly Invitae), Labcorp RCV002858048 SCV003228832 pathogenic Glycogen storage disease IXc 2022-08-11 criteria provided, single submitter clinical testing 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 variant has been observed in individual(s) with clinical features of glycogen storage disease (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This variant results in the deletion of part of exon 8 (c.648-2_648del) of the PHKG2 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 PHKG2 are known to be pathogenic (PMID: 8896567, 17689125, 21646031).
