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 25, 2024	This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1866 of the POLE protein (p.Ala1866Thr). This variant is present in population databases (rs377662540, gnomAD 0.008%). 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: 240567). 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 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. -

The POLE c.5596G>A variant is predicted to result in the amino acid substitution p.Ala1866Thr. This variant was reported in an individual with breast cancer; however a separate pathogenic variant was also identified in this individual (Table S4. Bhai et al. 2021. PubMed ID: 34326862). This variant was also reported in an individual with pancreatic adenocarcinoma (Table S2. Guenther et al. 2018. PubMed ID: 30194485). This variant is reported in 0.0077% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is classified as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/240567/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

The p.A1866T variant (also known as c.5596G>A), located in coding exon 41 of the POLE gene, results from a G to A substitution at nucleotide position 5596. The alanine at codon 1866 is replaced by threonine, an amino acid with similar properties. This amino acid position is well 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. -
