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.
