Genetic Disorder Reference Sheet: Multiple Endocrine Neoplasia Type 2

Multiple endocrine neoplasia type 2 is an autosomal dominant disease that occurs because of germline pathogenic variants in the rearranged during transfection (RET) proto-oncogene. The RET gene was isolated in 1993 and pathogenic variants affect 1–10 per 100,000 people. Approximately 50% of cases are de novo.
