GenAge entry for HTT (Homo sapiens)

Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism

Gene name (HAGRID: 98)

HGNC symbol: HTT
Aliases: IT15; HD
Common name: huntingtin

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism
Description: Mostly famous for causing Huntington disease, the exact functions of HTT are still unknown. While HTT appears to be involved in age-related changes [836], its exact role in human ageing is still being studied. In mice however, the deletion of the polyglutamine stretch resulted in the extension of mean and maximal lifespan [2135].
