Genes affected

POLD1 (HGNC:9175): (DNA polymerase delta 1, catalytic subunit) This gene encodes the 125-kDa catalytic subunit of DNA polymerase delta. DNA polymerase delta possesses both polymerase and 3' to 5' exonuclease activity and plays a critical role in DNA replication and repair. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6. [provided by RefSeq, Mar 2012]

Variant summary: The POLD1 c.356G>A (p.Arg119His) variant involves the alteration of a non-conserved nucleotide. 4/5 in silico tools predict a benign outcome for this variant. This variant was found in 13802/119582 control chromosomes (1139 homozygotes) at a frequency of 0.1154187, which is approximately 8125 times the estimated maximal expected allele frequency of a pathogenic POLD1 variant (0.0000142), suggesting this variant is likely a benign polymorphism. Taken together, this variant is classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The missense variant NM_001308632.1(POLD1):c.356G>A (p.Arg119His) has been reported to ClinVar as Benign with a status of (2 stars) criteria provided, multiple submitters, no conflicts (Variation ID 380220 as of 2024-12-05). The p.Arg119His variant is not predicted to introduce a novel splice site by any splice site algorithm. The p.Arg119His missense variant is predicted to be tolerated by both SIFT or PolyPhen2. The histidine residue at codon 119 of POLD1 is present in Orangutan and 4 other mammalian species. The nucleotide c.356 in POLD1 is not conserved according to a GERP++ and PhyloP analysis of 100 vertebrates. For these reasons, this variant has been classified as Benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
