Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_002691.4(POLD1):c.230C>G(p.Pro77Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. P77P) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 27, 2017 | In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a POLD1-related disease. This sequence change replaces proline with arginine at codon 77 of the POLD1 protein (p.Pro77Arg). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and arginine. - |
