GenAge entry for GHRHR (Homo sapiens)

Gene name (HAGRID: 222)

HGNC symbol: GHRHR
Aliases
Common name: growth hormone releasing hormone receptor

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to the regulation or control of genes previously linked to ageing
Description: GHRHR is mostly expressed in the pituitary and functions as the receptor for GHRH. Different splice variants appear to exist. Knock-out mice without GHRHR, called little mice, live about 25% longer than controls [5], but it is unclear whether their ageing process is delayed. Mutations in the human GHRHR gene have been associated with growth deficiency and dwarfism [1751], though there is no indication that these patients live longer. GHRHR might play a role in human ageing through the GH1/IGF1 axis.
