Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_006231.4(POLE):c.2612G>C(p.Ser871Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000743 in 1,614,100 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S871I) has been classified as Uncertain significance.

not provided Uncertain:3
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; This variant is associated with the following publications: (PMID: 20951805) -

This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 871 of the POLE protein (p.Ser871Thr). This variant is present in population databases (rs770470552, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 35534704). ClinVar contains an entry for this variant (Variation ID: 405751). 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 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. -

POLE-related disorder Uncertain:1
The POLE c.2612G>C variant is predicted to result in the amino acid substitution p.Ser871Thr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.020% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-133240684-C-G). This variant is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/405751/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Hereditary cancer-predisposing syndrome Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
