Clinical Experience in the Screening and Management of a Large Kindred With Familial Isolated Pituitary Adenoma Due to an Aryl Hydrocarbon Receptor Interacting Protein (AIP) Mutation

Abstract

Families with AIP mutations present particular problems such as the occurrence of large invasive tumors, poor response to medical treatment, difficulties with fertility and management of pregnancy, and the finding of AIP sequence variants of unknown significance. Because disease mostly develops at a younger age and penetrance is low, the timing and duration of the follow-up of carriers without overt disease requires further study. The psychological and financial impact of prolonged clinical screening must be considered. Excellent relationships between the family, endocrinologists, and geneticists are essential, and ideally these families should be managed in centers with specialist expertise.
