#ExistInterpData>Background Information for Multiple Endocrine Neoplasia, Type 2B (RET) 2 Mutations: Characteristics: Medullary carcinoma of the thyroid, pheochromocytoma, mucosal neuromas, and Marfanoid body habitus. Incidence: Approximately 1: 600,000 Inheritance: Autosomal dominant; 50 percent of cases caused by de novo mutations. Penetrance: 100 percent for medullary thyroid carcinoma, 50 percent for pheochromocytoma. Cause: RET proto-oncogene mutations. Mutations Tested: M918T, A883F. Clinical Sensitivity: 98 percent. Methodology: Polymerase chain reaction followed by unlabeled probe and melting curve analysis. Analytical Sensitivity and Specificity: 99 percent. Limitations: RET mutations, other than M918T and A883F, will not be identified.
