Abstract:
Multiple endocrine neoplasia type 2 (MEN 2) is a rare autosomal dominantly inherited familial cancer syndrome caused by mutations in the ret proto-oncogene. MEN 2 has three distinct subtypes, which are MEN 2A, MEN 2B and familial medullary thyroid carcinoma. Identification of a disease gene has enabled a DNA-based strategy for detection of direct mutation in patients with MEN 2 syndromes and in patients with sporadic medullary thyroid carcinoma. The identification of mutations responsible for MEN 2 syndromes has resulted in the routine identification of gene carriers early in life before the development of disease, causing timely prophylactic thyroidectomy in these patients. This report includes our clinical and molecular experience on Turkish MEN 2 families and patients with sporadic medullary thyroid carcinoma diagnosed and treated between 1994 and 2005.
Insights
Genetic testing for Multiple Endocrine Neoplasia type 2 (MEN 2) allows early detection of gene carriers. This enables prophylactic thyroidectomy, preventing disease development in individuals with MEN 2 syndromes.
Area of Science:
- Genetics
- Oncology
- Endocrinology
Background:
- Multiple Endocrine Neoplasia type 2 (MEN 2) is a rare, inherited cancer syndrome.
- Caused by mutations in the ret proto-oncogene, MEN 2 presents in three subtypes: MEN 2A, MEN 2B, and familial medullary thyroid carcinoma.
- Identifying the disease gene facilitates DNA-based mutation detection.
Purpose of the Study:
- To report clinical and molecular findings in Turkish MEN 2 families and sporadic medullary thyroid carcinoma patients.
- To highlight the impact of genetic identification on early diagnosis and management.
- To review experience between 1994 and 2005.
Main Methods:
- Genetic analysis of ret proto-oncogene mutations.
- Clinical evaluation of patients diagnosed with MEN 2 syndromes and sporadic medullary thyroid carcinoma.
- Review of patient data from 1994-2005.
Main Results:
- Established DNA-based strategies for mutation detection in MEN 2.
- Enabled early identification of gene carriers for MEN 2 syndromes.
- Facilitated timely prophylactic thyroidectomy in identified carriers.
Conclusions:
- Genetic testing for ret proto-oncogene mutations is crucial for diagnosing MEN 2 syndromes.
- Early detection and prophylactic surgery significantly improve outcomes for MEN 2 patients.
- This approach is vital for managing familial cancer syndromes.
