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 testingLabcorp Genetics (formerly Invitae), LabcorpJan 27, 2024This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1308 of the POLE protein (p.Arg1308Trp). This variant is present in population databases (rs763854815, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 240491). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on POLE protein function. 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. -
Colorectal cancer, susceptibility to, 12 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingSt. Jude Molecular Pathology, St. Jude Children's Research HospitalMay 04, 2021The POLE c.3922C>T (p.Arg1308Trp) missense change has a maximum non-founder population frequency of 0.029% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/12-133225975-G-A?dataset=gnomad_r2_1). Five of seven in silico tools predict a deleterious effect of this variant on protein function (PP3), but to our knowledge these predictions have not been confirmed by functional assays. This variant has been identified in a tumor with low tumor mutational burden (internal data). To our knowledge, this variant has not been reported in the literature in individuals with POLE-related disease. In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: PP3. -
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 25, 2022The p.R1308W variant (also known as c.3922C>T), located in coding exon 31 of the POLE gene, results from a C to T substitution at nucleotide position 3922. The arginine at codon 1308 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
