| Interpretive Data: |
Background Information:
Characteristics: Medullary carcinoma of the thyroid, pheochromocytoma, parathyroid adenoma/hyperplasia; dependent on specific MEN type 2 subtype.
Incidence: Approximately 1 in 30,000.
Inheritance: Autosomal dominant. 50% de novo mutations in MEN 2B.
Penetrance: Incomplete. Varies by subtype.
Cause: RET proto-oncogene mutations.
Mutations Detected: Mutations in exons 10, 11, and 13-16.
Clinical Sensitivity: 95%, 88%, and 98% for MEN 2A, FMTC, and MEN 2B, respectively.
Methodology: Bidirectional sequencing
Analytical Sensitivity and Specificity: Greater than 99%.
Limitations: Mutations in RET proto-oncogene introns, regulatory regions, or exons not targeted for sequencing will not be identified.
Counseling and informed consent are recommended for genetic testing. Consent forms are available online at www.aruplab.com.
