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

APTX is a member of the histidine triad superfamily encoding a number of transcripts. The APTX protein appears to be involved in DNA repair, and it interacts with DNA repair pathways as well as with ageing-related genes [1098]. Mutations in APTX have been associated with ataxia-ocular apraxia, a neurological disorder, as well as increased susceptibility to genotoxic stress [1099]. APTX has not been directly linked to human ageing, though a potential role should not be discarded.
