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:2

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Dec 18, 2020	Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Dec 24, 2023	This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2210 of the POLE protein (p.Lys2210Gln). This variant is not present in population databases (gnomAD no frequency). 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: 540727). 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. -

PreventionGenetics, part of Exact Sciences

Dec 11, 2023

The POLE c.6628A>C variant is predicted to result in the amino acid substitution p.Lys2210Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is classified as a variant of uncertain significance by outside laboratories in the ClinVar database (https://preview.ncbi.nlm.nih.gov/clinvar/variation/540727/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
