Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The NM_002691.4(POLD1):c.632G>C(p.Arg211Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000163 in 1,597,058 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. R211H) has been classified as Likely benign.

not provided Uncertain:1
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Colorectal cancer, susceptibility to, 10 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 211 of the POLD1 protein (p.Arg211Pro). This variant is present in population databases (rs373192520, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with POLD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 953892). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on POLD1 protein function. 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. -
