Rabson-Mendenhall syndrome: two case reports and a brief review of the literature

Abstract

Rabson-Mendenhall syndrome is a rare, autosomal recessive disorder characterized by insulin resistance syndrome, growth retardation, coarse and senile-looking faces, mental precocity, early dentition, and pineal hyperplasia. Mutations of the insulin receptor gene affecting insulin action appear to be the basic mechanism underlying this syndrome. We report on Rabson-Mendenhall syndrome in two siblings and briefly review the literature.
