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	Nov 30, 2022	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1364 of the POLE protein (p.Arg1364His). This variant is present in population databases (rs369171111, gnomAD 0.01%). This missense change has been observed in individual(s) with colorectal cancer (PMID: 31360874). ClinVar contains an entry for this variant (Variation ID: 405848). 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. -

Variant summary: POLE c.4091G>A (p.Arg1364His) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.4e-05 in 250788 control chromosomes. The observed variant frequency is approximately 3-fold of the estimated maximal expected allele frequency for a pathogenic variant in POLE causing Colorectal Cancer phenotype (1.4e-05, gnomAD), suggesting that the variant is benign. c.4091G>A has been reported in the literature in at least one individual affected with Colorectal Cancer without strong evidence of causality (Toh_2018). This report does not provide unequivocal conclusions about association of the variant with Colorectal Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 31360874). Three submitters have provided clinical-significance assessments for this variant to ClinVar after 2014, and classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly benign. -

The p.R1364H variant (also known as c.4091G>A), located in coding exon 32 of the POLE gene, results from a G to A substitution at nucleotide position 4091. The arginine at codon 1364 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
