Overview
Genetic Testing
- Identifying an MEN1 gene mutation in the proband early in the disease process can allow for early detection and treatment of tumors and earlier identification of at-risk family members.
- Many studies have been performed to determine the prevalence of MEN1 gene mutations among patients with apparently sporadic MEN1-related tumors.
- Genetic testing for mutations in MEN1 is recommended if one of the following conditions is present
- Gastrinoma at any age
- Multifocal duodenopancreatic NETs at any age
- Parathyroid hyperplasia/adenomas before age 30 or 40 years
- Multiglandular parathyroid adenomas/hyperplasia or recurrent primary hyperparathyroidism.
- Presence of one of the three main MEN1 tumors plus one of the less common tumors/findings
- Presence of two or more features (e.g., adrenal adenomas and carcinoid tumor)
- Individuals with isolated parathyroid and/or pituitary tumors are less likely to have an identifiable mutation than those with pancreatic tumors
- DNA sequencing is the primary method of genetic testing
