title: [Familial pituitary adenomas: clinical and genetic aspects].
abstract: Pituitary adenomas can occur in a familial context, or they can be isolated cases, sometimes due to a predisposing syndrome. In multiple endocrine neoplasia type 1, they often associate with a mutation of the menin gene, a tumor-suppressing gene. A new germinal mutation predisposing to the development of multiple endocrine neoplasias has recently been identified in MENI-negative subjects on the gene CDKN1B encoding for p27(kip1)protein. Carney Complex syndrome--a rare disease--is in more than 60% of the cases linked to the inactivation mutation of a gene located on 17q22-24 that encodes the regulatory subunit 1 of protein kinase A, PRKARIA. Isolated familial pituitary adenomas represent 1.9 to 3.2% of the population of subjects presenting a pituitary adenoma. Low penetrance non-sense mutations, Q14X, IVS3-IG>A and R304X, in 11q12-11q13 region encoding AIP protein, (Aryl hydrocarbon receptor Interacting Protein), have been described by Vierimaa et al, in Finish patients with pituitary adenoma predispositions.
