Rabson-Mendenhall Syndrome

📋Overview

This disorder belongs to a spectrum of severe insulin resistance syndromes caused by inherited mutations in the INSR gene, which encodes the insulin receptor. These genetic defects impair the body's ability to utilize insulin effectively, leading to significant disruptions in glucose metabolism and cellular signaling.

Clinical observations often link this condition to other insulin receptor-related disorders, such as Donohue syndrome. It typically manifests with distinctive physical features and metabolic abnormalities that arise from the underlying cellular inability to respond to insulin pathways.
