What Is Rabson-Mendenhall Syndrome?
Rabson-Mendenhall Syndrome (RMS) is a rare genetic disorder that primarily affects the body’s ability to regulate insulin, leading to severe insulin resistance. This condition is classified as a form of congenital generalized lipodystrophy, which means that individuals with RMS have a significant deficiency of adipose (fat) tissue. The syndrome is named after the two physicians, Dr. Rabson and Dr. Mendenhall, who first described it in the medical literature.
RMS is caused by mutations in the INSR gene, which encodes the insulin receptor. This gene is crucial for the proper functioning of insulin in the body, and when it is mutated, it leads to a range of metabolic issues. Individuals with Rabson-Mendenhall Syndrome often experience a variety of health challenges, including growth abnormalities, dental issues, and an increased risk of developing type 2 diabetes at a young age.
Understanding the Genetics of RMS
The genetic mutations responsible for Rabson-Mendenhall Syndrome are inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated gene for their child to be affected by the syndrome. Genetic testing can confirm the diagnosis, and understanding the genetic basis of RMS is crucial for managing the condition effectively.
