Core Tip

Core Tip: Gene sequencing was performed on an adult Asian female patient with bilateral pheochromocytoma and thyroid carcinoma. A mutation, characterized by a nucleotide (c.T1901A) and amino acid (p.Cys634Tyr) change, was identified, supporting multiple endocrine neoplasia type 2A development. Genetic screening of family members revealed the patient’s father and son are carriers of the mutation. Clinical follow-up direction and treatment plan were guided by genetic testing. The patient and her son were diagnosed with orthotopic medullary thyroid carcinoma, facilitating timely and early detection in the early stage of cancer and potentially improving the survival rate of patients.
