Gastrinomas are associated with which genetic syndrome?

Gastrinomas are associated with which genetic syndrome?

• A. MEN syndrome
• B. Zollinger-Ellison syndrome
• C. Serous cystadenoma
• D. Adenocarcinoma

Answer: (A)

Gastrinomas are commonly part of a hereditary endocrine neoplasia called MEN1 (multiple endocrine neoplasia type 1). MEN1 results from a MEN1 gene mutation and typically involves tumors in the parathyroids, pituitary, and pancreas. Among pancreatic neuroendocrine tumors, gastrinomas frequently appear in MEN1 patients, producing excess gastrin and causing gastric acid overproduction (the Zollinger-Ellison syndrome clinically). So the genetic syndrome most closely linked to gastrinomas is MEN1. Zollinger-Ellison syndrome describes the clinical effects of excess gastrin, not a hereditary syndrome. Serous cystadenoma and adenocarcinoma are pancreatic lesions not characteristically tied to MEN1.
