Submissions by phenotype
not provided Uncertain:2
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1041 of the POLE protein (p.Arg1041Gln). This variant is present in population databases (rs774645622, gnomAD 0.01%). 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: 473575). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on POLE protein function. 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. -

Hereditary cancer-predisposing syndrome Uncertain:1
The p.R1041Q variant (also known as c.3122G>A), located in coding exon 26 of the POLE gene, results from a G to A substitution at nucleotide position 3122. The arginine at codon 1041 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
