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]

This 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). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -

The p.I843V variant (also known as c.2527A>G), located in coding exon 22 of the POLE gene, results from an A to G substitution at nucleotide position 2527. The isoleucine at codon 843 is replaced by valine, an amino acid with highly similar properties. This alteration was reported in 1/107 Macedonian individuals with a clinical history of hereditary polyposis or hereditary non-polyposis colorectal cancer who underwent multi-gene panel testing (Staninova-Stojovska M et al. Balkan J Med Genet, 2019 Dec;22:5-16). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
