Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_006231.4(POLE):c.3121C>T(p.Arg1041Trp) variant causes a missense change. The variant allele was found at a frequency of 0.00000372 in 1,614,086 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1041G) has been classified as Uncertain significance.

not provided    Uncertain:1 
This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1041 of the POLE protein (p.Arg1041Trp). This variant is present in population databases (rs762140272, gnomAD 0.0009%). 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: 473574). 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) 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. -
Hereditary cancer-predisposing syndrome    Uncertain:1 
The p.R1041W variant (also known as c.3121C>T), located in coding exon 26 of the POLE gene, results from a C to T substitution at nucleotide position 3121. The arginine at codon 1041 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is highly 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. -
