Hereditary MTC is identified through  germline RET mutation  

 When to do Prophylactic thyroidectomy

 

Children identified to harbor the ATA highest-risk RET mutations (i.e., Met918Thr) are recommended to undergo total thyroidectomy in the first year of life.

In children with ATA high-risk mutations (i.e., codon Cys634 and Ala883Phe mutations), prophylactic thyroidectomy is typically recommended before 5 years of age, with the exact timing based on annual clinical examination, neck ultrasound, and serum calcitonin levels starting from the age of 3 years

Children with ATA moderate-risk RETmutations, the timing of prophylactic thyroidectomy should be based on the findings of clinical examination, neck ultrasound, and serum calcitonin concentrations commencing at age 5 years. 

Once calcitonin levels are greater than 30 pg/mL, the likelihood of nodal metastases increases, and this will often necessitate central node dissection, which is associated with increased operative morbidity and a reduction in duration of long-term remission.
