Genes affected
POLD3 (HGNC:20932): (DNA polymerase delta 3, accessory subunit) This gene encodes the 66-kDa 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. The encoded protein plays a role in regulating the activity of DNA polymerase delta through interactions with other subunits and the processivity cofactor proliferating cell nuclear antigen (PCNA). Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Mar 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.449C>G (p.S150W) alteration is located in exon 6 (coding exon 6) of the POLD3 gene. This alteration results from a C to G substitution at nucleotide position 449, causing the serine (S) at amino acid position 150 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
