| Invitae | RCV000633232 | SCV000754448 | likely pathogenic | Werner syndrome | 2023-08-16 | 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 13 and introduces a premature termination codon (Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. ClinVar contains an entry for this variant (Variation ID: 528149). This variant has not been reported in the literature in individuals affected with WRN-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change affects a donor splice site in intron 13 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. |
