The majority of pituitary adenomas occur sporadically, however, about 5% of all cases occur in a familial setting, of which over half are due to multiple endocrine neoplasia type 1 (MEN-1) and Carney's complex (CNC). Since the late 1990s we have described non-MEN1/CNC familial pituitary tumours that include all tumour phenotypes, a condition named familial isolated pituitary adenomas (FIPA). The clinical characteristics of FIPA vary from those of sporadic pituitary adenomas, as patients with FIPA have a younger age at diagnosis and larger tumours. About 15% of FIPA patients have mutations in the aryl hydrocarbon receptor interacting protein gene (AIP), which indicates that FIPA may have a diverse genetic pathophysiology. This review describes the clinical features of familial pituitary adenomas like MEN1, the MEN 1-like syndrome MEN-4, CNC, FIPA, the tumour pathologies found in this setting and the genetic/molecular data that have been recently reported.

Familial pituitary adenomas are found in multitumoral syndromes such as multiple endocrine neoplasia type 1 (NEM1) and type 4 (NEM4) and the Carney complex (CNC); it remains at present the only known condition in the category of familial isolated pituitary adenomas (FIPA). Familial adenomas account for 3-5% of all pituitary adenomas. Their pathogenesis is known in part: mutations of the menin gene in NEM1 (80%), of the CDKN1B gene in NEM4 (several cases described), of the PRKR1A gene in CNC (50%) and the AIP gene in 15% of FIPA cases (50% of the FIPA cases with a homogeneous somatotropic phenotype). The clinical course of familial adenoma with NEM1 or FIPA is more aggressive than that of sporadic adenoma, with more macroadenomas and more patients diagnosed younger. Familial pituitary adenomas are distinguished from the sporadic forms in their genetic, epidemiologic and clinical characteristics. They require a differentiated management, especially concerning screening. [less ▲]

BACKGROUND: Pituitary adenomas occur in a familial setting in about 5% of all cases and over half of these are due to multiple endocrine neoplasia type 1 (MEN1) and Carney complex (CNC). Since the late 1990s, we have described non-MEN1/CNC familial pituitary tumors that include all tumor phenotypes and have named this condition 'familial isolated pituitary adenoma' (FIPA). Clinical features of FIPA differ from those of sporadic pituitary adenomas in that patients with FIPA are often younger and have larger tumors at diagnosis. About 15% of FIPA patients have mutations in the aryl hydrocarbon receptor interacting protein gene (AIP), which indicates that FIPA may have a diverse genetic pathophysiology. We review the clinical features of FIPA, the tumor pathologies found in this setting and the genetic/molecular data that have been recently reported. CONCLUSIONS: Clinically relevant pituitary adenomas are more common than previously thought and occur in a familial setting in about 5% of cases overall. Therefore, specific questioning regarding family history of pituitary disease should be part of the workup of all patients with pituitary adenomas, not just those with acromegaly. FIPA is a useful clinical framework to study the features of pituitary adenomas that occur in a familial setting since it encompasses all tumor phenotypes and heterogeneous/homogeneous expression among affected family members.
