Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM1BP4_Strong
The NM_006231.4(POLE):c.3890C>T(p.Ser1297Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000267 in 1,612,948 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S1297S) has been classified as Likely benign.

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1297 of the POLE protein (p.Ser1297Leu). This variant is present in population databases (rs746585658, gnomAD 0.005%). This missense change has been observed in individual(s) with breast cancer (PMID: 28202063). ClinVar contains an entry for this variant (Variation ID: 240486). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -
In silico analysis indicates that this missense variant does not alter protein structure/function; Observed in individual(s) with breast cancer (PMID: 28202063); This variant is associated with the following publications: (PMID: 29056344, 28202063) -

Hereditary cancer-predisposing syndrome Uncertain:1Benign: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. -
