Invitae RCV002012480 SCV002280789 likely pathogenic Werner syndrome 2021-11-29 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Studies have shown that disruption of this splice site results in skipping of exon 30 and introduces a premature termination codon (PMID: 16673358). The resulting mRNA is expected to undergo nonsense-mediated decay. Disruption of this splice site has been observed in individual(s) with Werner syndrome (PMID: 16673358, 25059010). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 29 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.
