Neoplasia endócrina múltipla tipo 1: diagnóstico clínico, laboratorial e molecular e tratamento das doenças associadas

Abstract: RESUMOAs síndromes de neoplasias endócrinas múltiplas (NEM) incluem as do tipo 1 (MEN 1) e 2 (MEN 2), a síndrome de von Hippel-Lindau, neurofibromatose tipo 1 e o complexo de Carney. Estas são síndromes genéticas complexas decorrentes de ativação ou inativação de diferentes tipos de genes envolvidos na regulação da proliferação celular. Nesta revisão, discutiremos as manifestações clínicas e o acompanhamento da MEN 1, assim como o rastreamento genético de potenciais portadores de alterações no gene MEN 1. A ME… Show more

“…Of note, the molecular diagnosis preformed in this case was crucial for the close surveillance of Pheo that has allowed early diagnosis and management of this potential fatal disorder. HPT is also one of the major components of the multiple neoplasia type 1 (MEN1) (15).…”

“…They are germ mutations, in heterozygosis, resulting from an unexpressed allele, which leads to haploinsufficiency (2). On the other hand, in MEN1 the causative gene, located in the 11q13 chromosome, consists of 10 exons and encodes a protein, composed of 610 amino acids, called menin (3,5). Even though the functional role of this protein has not yet been totally elucidated, inactivating mutations in this gene are associated with the development of endocrine tumors (6).…”

“…In MEN1, hyperparathyroidism is present in 90 to 97% of the patients, generally as a primary manifestation, as the consequence of two or more parathyroid hyperplasias, contrary to sporadic cases that have only one parathyroid adenoma as the most frequent cause (4,5). In CNC no occurrence of compromised parathyroid was found.…”
