GeneDx RCV000579073 SCV000681061 pathogenic not provided 2017-10-31 criteria provided, single submitter clinical testing The Y621X variant in the GNE gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The variant is not observed in large population cohorts (Lek et al., 2016). We interpret Y621X as a pathogenic variant.
Invitae RCV002526936 SCV003272635 pathogenic GNE myopathy; Sialuria 2022-10-03 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. ClinVar contains an entry for this variant (Variation ID: 489077). This variant has not been reported in the literature in individuals affected with GNE-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr621*) in the GNE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GNE are known to be pathogenic (PMID: 24027297).
