  MEN1 GENE ANALYSIS FOR MULTIPLE ENDOCRINE NEOPLASIA TYPE 1

· Mutation analysis of the MEN1 gene by sequencing the coding region (exons 2-10) and splice sites

  Germline mutations in the MEN1 gene are found in approximately 90% of patients with familial MEN1 and 75% of sporadic cases.        

Reporting time:       1- 6 weeks

Cost:                     Sequencing of exons 2, 3, 4, 5, 6, 7, 8, 9 and 10       £400

                             Testing for known mutation in family member           £75

  RET GENE ANALYSIS FOR MULTIPLE ENDOCRINE NEOPLASIA TYPES 2A AND 2B (MEN2A AND 2B) AND FAMILIAL MEDULLARY THYROID CARCINOMA (FMTC)

  · Mutation analysis of the RET proto-oncogene by sequencing of exons 10, 11, 13, 14, 15 and 16     

  as appropriate.

  Mutations in the RET proto-oncogene (exons 10 and 11) are found in >95% of MEN2A patients. Familial medullary thyroid carcinoma (FMTC) may be caused by mutations in exons 10, 11, 13 or 14. Although most MEN2B patients have the M918T mutation in exon 16, several families have been reported with an exon 15 mutation (A883F).  Genetic testing of the RET gene is recommended in all cases of medullary thyroid carcinoma, even if they are apparently spontaneous.

Reporting time:       1- 6 weeks

Cost:                     Sequencing of exons 10, 11, 13, 14, 15 and 16                   £250

                             Sequencing of exons 15 and 16 (MEN2B)                   £100

                             Testing for known mutation in family member           £75
