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 arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 52 of the POLE protein (p.Arg52Trp). This variant is present in population databases (rs115452881, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 35264596, 35534704). ClinVar contains an entry for this variant (Variation ID: 240396). 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R52W variant (also known as c.154C>T), located in coding exon 2 of the POLE gene, results from a C to T substitution at nucleotide position 154. The arginine at codon 52 is replaced by tryptophan, an amino acid with dissimilar properties. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The POLE c.154C>T (p.Arg52Trp) missense change has a maximum subpopulation frequency of 0.025% 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 to our knowledge functional studies have not been performed. To our knowledge, 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. -

The POLE c.154C>T variant is predicted to result in the amino acid substitution p.Arg52Trp. This variant has been reported in a cohort of individuals with a history breast cancer, but was interpreted as uncertain (Supplementary Table 3, Guindalini et al. 2022. PubMed ID: 35264596). This variant is reported in 0.025% of alleles in individuals of Latino descent in gnomAD. This variant is interpreted as uncertain significance by the vast majority of submitters in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/240396/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
