GenAge entry for IGF2 (Homo sapiens)

Gene name (HAGRID: 29)

HGNC symbol: IGF2
Aliases: FLJ44734; IGF-II; C11orf43
Common name: insulin-like growth factor 2

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: Like IGF1, IGF2 is involved in growth and development. Unlike IGF1, IGF2 appears to be only active at early stages of development, such as embryonic growth. IGF2's role in ageing is unproven and its interest derives mostly from its connection with IGF1 and how the IGF1/GH1 axis appears to regulate ageing in model organisms [425]. Mice with disrupted IGF2 are growth-deficient but their lifespan has not been studied [1309]. Polymorphisms in the human IGF2 gene have been associated with body mass index in adult males [1656].
