Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_002691.4(POLD1):c.1811C>A(p.Ser604Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,613,956 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. S604A) has been classified as Uncertain significance.

Colorectal cancer, susceptibility to, 10 Uncertain:1
This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 604 of the POLD1 protein (p.Ser604Tyr). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 407972). 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. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.S604Y variant (also known as c.1811C>A), located in coding exon 14 of the POLD1 gene, results from a C to A substitution at nucleotide position 1811. The serine at codon 604 is replaced by tyrosine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
