Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.
The NM_006231.4(POLE):c.89C>T(p.Ser30Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000409 in 1,614,050 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. S30S) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 26, 2024 | This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 30 of the POLE protein (p.Ser30Leu). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with breast cancer (PMID: 34326862). ClinVar contains an entry for this variant (Variation ID: 473839). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Dec 12, 2023 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in an individual with a personal and family history of breast cancer, melanoma, and other cancers (PMID: 34326862); This variant is associated with the following publications: (PMID: 28135145, 32627883, 29056344, 34326862) - |
