Description

The Q40X nonsense variant in the AGL gene has been reported previously in individuals with glycogen storage disease type III who were also found to harbor a second AGL gene variant (Austin et al., 2012; Li et al., 2014 ). The Q40X variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. In summary, we interpret this variant as pathogenic.
