Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_002691.4(POLD1):c.1371G>A(p.Met457Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Uncertain significance (★). Another nucleotide change resulting in same amino acid change has been previously reported as Uncertain significancein ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M457T) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 06, 2018 | The p.M457I variant (also known as c.1371G>A), located in coding exon 10 of the POLD1 gene, results from a G to A substitution at nucleotide position 1371. The methionine at codon 457 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is highly conserved through mammals but not in all available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
