Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong
The NM_006231.4(POLE):c.3620C>T(p.Pro1207Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000155 in 1,613,972 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Submissions by phenotype
not provided Uncertain:2
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 29056344) -
This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1207 of the POLE protein (p.Pro1207Leu). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 240473). 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.3620C>T variant is predicted to result in the amino acid substitution p.Pro1207Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.044% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-133226438-G-A). This variant is listed in ClinVar as uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/240473/). 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. -
