Multiple endocrine adenomatosis: in support of the common origin theories.

Herein we give clinical support to the theory of a common origin of multiple endocrine adenomatosis.

Such an approach is now made possible by the radioimmunoassay. Chromosome patterns and histocompatibility antigens are reviewed in a family with the disease.
