Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_006231.4(POLE):āc.1345A>Gā(p.Thr449Ala) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,532 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. T449M) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 02, 2022 | 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. 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. ClinVar contains an entry for this variant (Variation ID: 540719). This variant has not been reported in the literature in individuals affected with POLE-related conditions. This variant is present in population databases (rs747935432, gnomAD 0.0009%). This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 449 of the POLE protein (p.Thr449Ala). - |
