A novel MEN syndrome was discovered, initially in rats (MENX), and later in humans (MEN4), which is caused by germline mutations in the putative tumor suppressor <i>CDKN1B</i> The most common phenotype of the 19 established cases of MEN4 that have been described to date is PHPT followed by pituitary adenomas.

Germline mutations in p27(kip1) are associated with increased susceptibility to multiple endocrine neoplasias (MEN) both in rats and humans; however, the potential role of common polymorphisms of this gene in endocrine tumor susceptibility and tumorigenesis remains mostly unrecognized.

Four major forms of MEN, which are autosomal dominant disorders, are recognized and referred to as: MEN type 1 (MEN1), due to menin mutations; MEN2 (previously MEN2A) due to mutations of a tyrosine kinase receptor encoded by the rearranged during transfection (RET) protoncogene; MEN3 (previously MEN2B) due to RET mutations; and MEN4 due to cyclin-dependent kinase inhibitor (CDNK1B) mutations.

Lately, a new type of MEN was identified (named MEN4) which is due to mutations in the CDKN1B gene, encoding for p27kip1 (p27), a cyclin-dependent kinase (Cdk) inhibitor that regulates the transition of cells from G1 to S phase. p27 is a non-canonical tumor suppressor since it is usually not somatically mutated in human cancers but it is often downregulated by post-translational mechanisms.

In this chapter we present the MENX syndrome and its phenotype, and we compare it to the human MEN syndromes; we discuss the current state of knowledge regarding the genes associated to inherited MEN, with a particular focus on CDKN1B; we present recent clinical and basic findings about the MEN4 syndrome and the functional characterization of the CDKN1B mutations identified.

This editorial summarizes some of these advances: the identification of the AIP, and the PDE11A and PDE8B genes by genome-wide association (GWA) studies as predisposing genes for pituitary and adrenal tumours, respectively, the discovery of p27 mutations in a new form of MEN similar to MEN type 1 (MEN 1) that is now known as MEN 4, the molecular investigations of Carney triad (CT), a disorder that associates paragangliomas (PGLs), gastrointestinal stromal tumour (GISTs), and pulmonary chondromas (PCH) with pheochromocytomas and adrenocortical adenomas and other lesions, and the molecular elucidation of the association of GISTs with paragangliomas (Carney-Stratakis syndrome) that is now known to be because of SDHB, SDHC, and SDHD mutations.

The cyclin-dependent kinase inhibitor p27 (CDKN1B) is a downstream target of menin and has been recently shown to be responsible for the multiple endocrine neoplasia-like syndrome in rats, where affected animals develop multiple tumors and hyperplasia in endocrine tissues, including the pancreatic islets of Langerhans.
