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]

Submissions by phenotype

Colorectal cancer, susceptibility to, 10 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 19, 2023This variant, c.125_136del, results in the deletion of 4 amino acid(s) of the POLD1 protein (p.Glu42_Glu45del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). 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: 439249). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2020The c.125_136del12 variant (also known as p.E42_E45del) is located in coding exon 1 of the POLD1 gene. This variant results from an in-frame AGGAGATGGAGG deletion at nucleotide positions 125 to 136. This results in the in-frame deletion of 4 amino acids between codons 42 and 45. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
