Abstract
The coexistence of multiple endocrine neoplasia type 1 (MEN1) and type 2A (MEN2A) is a rare occurrence and has been reported only twice in the literature. We present a patient with primary hyperparathyroidism and medullary thyroid cancer with strong family history of both MEN1- A nd MEN2A-associated conditions. Genetic testing showed the patient had a novel MEN1 loss-of-function mutation, c0.525_526insTT (p.Ala176Leufs*10), and an uncommon Cys630Tyr RET mutation. This case highlights the importance of obtaining a detailed family history when heritable endocrine disorders are suspected.
