It is possible that the main title of the report Rabson-Mendenhall Syndrome is not the name you expected.
Rabson-Mendenhall syndrome is an extremely rare genetic disorder characterized by severe insulin resistance. Insulin, a hormone produced by the pancreas, regulates blood sugar levels by promoting the movement of glucose (a simple sugar) into cells for energy production or into the liver and fat cells for storage.
Initial symptoms of Rabson-Mendenhall syndrome include abnormalities of the head and face (craniofacial region), abnormalities of the teeth and nails, and skin abnormalities such as acanthosis nigricans, a skin disorder characterized by abnormally increased coloration (hyperpigmentation) and "velvety" thickening (hyperkeratosis) of the skin, particularly of skin fold regions, such as of the neck, groin, and under the arms. In most cases, additional symptoms are present. Rabson-Mendenhall syndrome is inherited as an autosomal recessive trait. Infants are found to have very little fat, and there will be concern about failure to thrive, as the infant is not meeting weight standards on a growth chart, despite frequent feedings.
