(A;T) 5.8 Multiple Endocrine Neoplasia Type 1
(T;T) 0 common in clinvar

This is a genotype with recommended actions if clinically confirmed. In brief:

  • Multiple Endocrine Neoplasia Type I (MEN) is a hereditary cancer syndrome caused by MEN1 gene mutations. Manifestations include varying combinations of more than 20 endocrine and non-endocrine tumors.
  • Parathyroid tumors, which cause PHPT, are the most common feature and the first clinical manifestation in 90% of individuals with MEN1 with onset typically between ages 20 and 25 years.
  • Patients with MEN1 should be managed by a multidisciplinary team consisting of relevant specialists (such as endocrinologist, gastroenterologist, oncologist, clinical geneticist) with experience in the management of endocrine disorders.
  • Annual surveillance recommendations include biochemical (phlebotomy), clinical, and non-invasive imaging (such as CT).
  • Medical management of manifestations is dependent on tumor type and extent of disease. Most patients will require parathyroidectomy, and prophylactic thymectomy may also be recommended.
