Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP3
The NM_006231.4(POLE):c.4892G>T(p.Arg1631Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,461,220 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R1631C) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Nov 17, 2016 | The p.Arg1631Leu variant in POLE has not been previously reported in individuals with colorectal cancer but has been identified in 1/66346 of European chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs775590365). Computational prediction tools and conservation analysis do no t provide strong support for or against an impact to the protein. In summary, th e clinical significance of the p.Arg1631Leu variant is uncertain. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 12, 2020 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 517161). This variant is present in population databases (rs775590365, ExAC 0.002%). This sequence change replaces arginine with leucine at codon 1631 of the POLE protein (p.Arg1631Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. - |
