Invitae RCV000798163 SCV000937764 pathogenic Werner syndrome 2023-12-22 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 28 of the WRN gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or disrupted protein product. This variant is present in population databases (no rsID available, gnomAD 0.003%). Disruption of this splice site has been observed in individual(s) with Werner syndrome (PMID: 8968742). ClinVar contains an entry for this variant (Variation ID: 644283). Studies have shown that disruption of this splice site results in skipping of exon 28 and introduces a premature termination codon (PMID: 8968742, 16673358; Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic.
