1 In patients with medullary thyroid carcinoma (MTC) and type 2A multiple endocrine neoplasia (MEN2A), mutations of cysteine residues in the extracellular juxtamembrane region of the RET receptor tyrosine kinase cause the formation of covalent receptor dimers linked by intermolecular disulfide bonds between unpaired cysteines, followed by oncogenic activation of the RET kinase.

6 When introduced in the context of C634R - a cysteine replacement that is prevalent in MEN2A cases - the A639G/A641R mutations significantly reduced dimer formation and transforming activity in this otherwise highly oncogenic RET variant. Cysteine ret proto-oncogene Homo sapiens
