Description

This sequence change creates a premature translational stop signal (p.Gln395*) in the AGL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AGL are known to be pathogenic (PMID: 19299494). 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 glycogen storage disease (PMID: 29794575). This variant is not present in population databases (gnomAD no frequency).
