| Invitae | RCV000467790 | SCV000547516 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2023-12-08 | criteria provided, single submitter | clinical testing | This sequence change affects codon 796 of the POLD1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the POLD1 protein. RNA analysis indicates that this variant induces altered splicing and likely results in a shortened protein product. This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POLD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 407971). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that this variant results in skipping of exon 19, but is expected to preserve the integrity of the reading-frame (Invitae). 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. |
