Genes affected
POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 18, 2024This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 843 of the POLE protein (p.Ile843Val). This variant is present in population databases (rs780758461, gnomAD 0.004%). This missense change has been observed in individual(s) with ovarian cancer (PMID: 34326862). ClinVar contains an entry for this variant (Variation ID: 240435). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt POLE protein function with a positive predictive value of 80%. 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. -
Uncertain significance, criteria provided, single submitterclinical testingGeneDxAug 10, 2023Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with a personal and/or family history of oligopolyposis, breast cancer, and/or other cancers (Staninova-Stojovska et al., 2019; Bhai et al., 2021); This variant is associated with the following publications: (PMID: 29056344, 20951805, 34326862, 31942411) -
