Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_006231.4(POLE):c.5350G>A(p.Glu1784Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. E1784Q) has been classified as Uncertain significance.

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 21, 2017 | In summary, this variant has uncertain impact on POLE function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals with a POLE-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with lysine at codon 1784 of the POLE protein (p.Glu1784Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 07, 2023 | The p.E1784K variant (also known as c.5350G>A), located in coding exon 39 of the POLE gene, results from a G to A substitution at nucleotide position 5350. The glutamic acid at codon 1784 is replaced by lysine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
