Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_006231.4(POLE):c.4813G>A(p.Glu1605Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,460,986 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. E1605D) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 01, 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with POLE-related disease. ClinVar contains an entry for this variant (Variation ID: 473693). This variant is present in population databases (rs768801696, ExAC 0.003%). This sequence change replaces glutamic acid with lysine at codon 1605 of the POLE protein (p.Glu1605Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. - |
