When that person’s short-term prognosis is poor, or their health is unstable, urgent storage of a blood sample may be prudent. The goal of storing a blood sample is to allow for the possibility of hereditary cancer genetic testing in a family. [bccancer.bc.ca]

Second-hit mutations in MEN1 have been documented in angiofibromas, collagenomas, and lipomas in patients with MEN1. [12, 13, 14] Epidemiology Frequency Worldwide, the frequency of MEN1 is estimated to be 1 case in 30,000 persons. [15] Race- and sex-related [emedicine.medscape.com]

Pathophysiology MEN2B is secondary to a germline mutation in the RET proto-oncogene on chromosome 10q11. The most common mutation (95%) is M918T in exon 16 and second most common mutation (2-3%) is A883F in exon 15 [3]. [webeye.ophth.uiowa.edu]

This gene encodes p27Kip1, a putative tumor suppressor which binds to and inhibits cyclin/cyclin-dependent kinase complexes, thereby preventing cell cycle progression. [ncbi.nlm.nih.gov]

Though menin appears to be necessary to prevent tumor formation, it is not clear how the lack of this protein leads to specific tumors characteristic of multiple endocrine neoplasia type 1. [ivami.com]

The risk of developing MTC depends on RET mutation and can be prevented with prophylactic thyroidectomy. [cancerbiomed.org]

If a high-risk mutation is found, the thyroid gland should be surgically removed to prevent cancer from developing. Depending on the type of mutation, the timing of surgery could be as early as first months of life to childhood or young adulthood. [cancer.net]
