Description

DNA sequence analysis of the POLD1 gene demonstrated a sequence change, c.811G>A, in exon 7 that results in an amino acid change, p.Gly271Arg. This sequence change does not appear to have been previously described in patients with POLD1-related disorders and has also not been described in population databases (gnomAD, ExAC). The p.Gly271Arg change affects a highly conserved amino acid residue located in a domain of the POLD1 protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Gly271Arg substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Gly271Arg change remains unknown at this time.
