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 submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 05, 2024	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 2165 of the POLE protein (p.Arg2165Cys). This variant is present in population databases (rs369549727, gnomAD 0.005%). 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: 240597). 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Dec 01, 2023	Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 19296856) -

The p.Arg2165Cys variant in POLE has not been previously reported in the literat ure in individuals with colorectal cancer but has been reported by other clinica l laboratories in ClinVar (Variation ID 240597). It has also been identified in 1/18498 East Asian chromosomes by gnomAD (http://gnomad.broadinstitute.org; dbSN P rs369549727). Computational prediction tools and conservation analysis suggest that the p.Arg2165Cys variant may impact the protein, though this information i s not predictive enough to determine pathogenicity. In summary, the clinical sig nificance of the p.Arg2165Cys variant is uncertain. ACMG/AMP Criteria applied: P P3, PM2. -
