Description

The p.D294H variant (also known as c.880G>C), located in coding exon 7 of the POLD1 gene, results from a G to C substitution at nucleotide position 880. The aspartic acid at codon 294 is replaced by histidine, an amino acid with similar properties. This amino acid position is conserved. 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.
