Multiple endocrine neoplasia all but abandoned in the medical literature. Another early report was Schimke "et al." in 1968. OMIM also includes a fourth form of multiple endocrine neoplasia ("MEN4"), associated with CDKN1B. The presentation is believed to overlap that of MEN1 and MEN2. The "MEN1" gene consists of ten exons, spanning about 10 kb, and encodes a 610 amino acid protein named menin. The first exon and the last part of exon 10 are not translated. A main transcript of 2.8 kb has been described in a large variety of human tissues (pancreas, thymus, adrenal glands, thyroid, testis, leukocytes, heart, brain, lung,
