NM_006231.4:c.2131T>C
Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_006231.4(POLE):c.2131T>C(p.Ser711Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,609,994 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign 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. S711F) has been classified as Uncertain significance.

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: 23376243, 20951805) -
This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 711 of the POLE protein (p.Ser711Pro). This variant is present in population databases (rs374800058, gnomAD 0.07%). 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: 405853). 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.2131T>C variant is predicted to result in the amino acid substitution p.Ser711Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.069% of alleles in individuals of Ashkenazi Jewish descent in gnomAD and has been interpreted as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/405853/). 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 Uncertain:1
The p.S711P variant (also known as c.2131T>C), located in coding exon 19 of the POLE gene, results from a T to C substitution at nucleotide position 2131. The serine at codon 711 is replaced by proline, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
