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]

Colorectal cancer, susceptibility to, 12 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingSt. Jude Molecular Pathology, St. Jude Children's Research HospitalJan 23, 2024The POLE c.109C>T (p.Arg37Trp) missense change has a maximum subpopulation frequency of 0.0065% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and Functional studies have not been performed. This variant has not been reported in the literature in individuals with POLE-related disease. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 22, 2023This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 37 of the POLE protein (p.Arg37Trp). This variant is present in population databases (rs753101641, gnomAD 0.006%). 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: 540690). 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 not expected to disrupt POLE protein function with a negative 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. -
