Background: Aryl hydrocarbon receptor-interacting protein (AIP) has been identified as a tumour suppressor gene in pituitary gland, causing 10% of all familial isolated pituitary adenoma. Patients with heterozygous loss-of-function germline mutation of AIP develop young-onset growth hormone and/or prolactin-secreting pituitary tumours. Homozygous loss of AIP leads to embryonic lethality in several animal models (mouse, fruit fly, round worm). Mouse e...

Aryl hydrocarbon receptor-interacting protein (AIP) is a highly expressed, evolutionary conserved little-known co-chaperone molecule that can bind to client proteins. Heterozygous loss-of-function mutations of AIP are associated with pituitary adenomas. Multiple lines of evidence suggest that AIP has important functions beyond the pituitary gland. Homozygous loss of AIP is lethal, with cardiac abnormalities seen in mice and failure-to-thrive seen in fruit flies and C.elegans. ...
