| Invitae | RCV000700894 | SCV000829671 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2022-09-01 | criteria provided, single submitter | clinical testing | 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. Studies have shown that disruption of this splice site results in skipping of exon 24, but is expected to preserve the integrity of the reading-frame (Invitae). ClinVar contains an entry for this variant (Variation ID: 578009). This variant has not been reported in the literature in individuals affected with POLD1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change affects an acceptor splice site in intron 23 of the POLD1 gene. Missense variants that disrupt the 3'-5' exonuclease (proof-reading) activity of the POLD1 protein are associated with PPAP (polymerase proofreading–associated polyposis) (PMID: 23263490, 23447401). However, loss-of-function variants that result in an absent or severely disrupted POLD1 protein, and missense variants outside the exonuclease domain, are unlikely to be associated with PPAP. |
