Multiple Endocrine Neoplasia 1 (MEN1)

  • Periodic screening for MEN1-associated endocrine tumors beginning in early childhood and continuing for life (NCCN, 2017)
  • Risk for malignant progression of MEN1-associated tumors depends on tumor type
    • Malignancy uncommon before early adulthood

Multiple Endocrine Neoplasia 2 (MEN2)

Multiple endocrine neoplasia (MEN) syndromes are characterized by tumors involving multiple endocrine glands. Subtypes MEN1 and MEN2 are distinguished by clinical features and molecular testing. MEN2 includes the additional subtypes MEN2A, MEN2B, and familial medullary thyroid carcinoma (FMTC).

Tests generally appear in the order most useful for common clinical situations. Click on number for test-specific information in the ARUP Laboratory Test Directory.

Multiple Endocrine Neoplasia Type 1 (MEN1) Sequencing and Deletion/Duplication 2005360
Method: Polymerase Chain Reaction/Sequencing/Multiplex Ligation-dependent Probe Amplification

Limitations 

Not evaluated – regulatory region variants, deep intronic variants, breakpoints of large deletions/duplications, and variants in genes other than MEN1

Diagnostic errors can occur due to rare sequence variations

Multiple Endocrine Neoplasia Type 2 (MEN2), RET Gene Mutations by Sequencing 0051390
Method: Polymerase Chain Reaction/Sequencing

Limitations 

Not evaluated – regulatory region variants, deep intronic variants, large deletions/duplications, and RET exons other than 5, 8, 10, 11, 13-16 

Diagnostic errors can occur due to rare sequence variations

Familial Mutation, Targeted Sequencing 2001961
Method: Polymerase Chain Reaction/Sequencing
