Clinical Information
A form of multiple endocrine neoplasia characterized by the presence of medullary carcinoma (carcinoma, medullary) of the thyroid gland, and usually with the co-occurrence of pheochromocytoma, producing calcitonin and adrenaline, respectively. Less frequently, it can occur with hyperplasia or adenoma of the parathyroid glands. This disease is due to gain-of-function mutations of the men2 gene on chromosome 10 (locus: 10q11.2), also known as the ret proto-oncogene that encodes a receptor protein-tyrosine kinase. It is an autosomal dominant inherited disease
Multiple endocrine neoplasia caused by mutation of the ret gene. Patients develop medullary thyroid carcinomas, and may also develop pheochromocytomas and parathyroid gland hyperplasia
