GenAge entry for POLD1 (Homo sapiens)

Gene name (HAGRID: 118)

HGNC symbol: POLD1
Aliases: CDC2; POLD
Common name: polymerase (DNA directed), delta 1, catalytic subunit

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence showing that the gene product to be a target of genes previously linked to ageing
Description: POLD1 is mostly involved in DNA synthesis, and probably it also functions in DNA repair [920]. Mice with a proofreading-deficient version of POLD1 have a higher cancer incidence [917]. POLD1 has also been associated with WRN [922]. There is no direct evidence linking POLD1 to human ageing, but it should be considered a suspect gene.
