BACKGROUND AND OBJECTIVES Medullary thyroid carcinoma (MTC) occurs both sporadically and In the autosomal domlnantly inherited multiple endocrine neoplasia (MEN) type 2 syndromes. The distinction between true sporadic MTC and a new mutation familial case is important for future clinical managment of both the patient and family. The susceptibility gene for MEN 2 is theRET proto‐oncogene. Systematic analysis for germ‐line mutations of theRET proto‐oncogene was performed in a series of 67 patients with apparently sporadic MTC to determine whether they were true sporadic cases or unsuspected de novo MEN 2 cases.
