Invitae RCV000801878 SCV000941676 uncertain significance Werner syndrome 2022-07-19 criteria provided, single submitter clinical testing This sequence change falls in intron 29 of the WRN gene. It does not directly change the encoded amino acid sequence of the WRN protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is present in population databases (no rsID available, gnomAD 0.02%). This variant has been observed in individual(s) with clinical features of Werner syndrome (PMID: 9225981). ClinVar contains an entry for this variant (Variation ID: 647377). Studies have shown that this variant results in altered splicing and introduces a premature termination codon (PMID: 9225981). The resulting mRNA is expected to undergo nonsense-mediated decay. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
