Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_006231.4(POLE):c.5863G>T(p.Asp1955Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign 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. D1955N) has been classified as Likely benign.

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 06, 2018 | This variant has not been reported in the literature in individuals with POLE-related disease. This sequence change replaces aspartic acid with tyrosine at codon 1955 of the POLE protein (p.Asp1955Tyr). The aspartic acid residue is weakly conserved and there is a large physicochemical difference between aspartic acid and tyrosine. This variant is not present in population databases (ExAC no frequency). 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"). 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. - |
