Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description

POLB is involved in DNA maintenance, replication, and recombination. It appears to play a role in DNA repair and it interacts with WRN [1520]. In mice, POLB haploinsufficiency increases cancer risk with age. While lifespan is not significantly altered, haploinsufficient mice may exhibit an increase in age-related mortality [1815]. POLB's role, if any, in human ageing remains to be determined.
