title: [Insulin receptor defect as a cause of Rabson-Mendenhall syndrome and other rare genetic insulin resistance syndromes].
abstract: Insulin plays a very important role in maintaining homeostasis of the whole organism. It regulates glucose metabolism, glycogen synthesis, lipid and protein metabolism. Insulin receptors are present in virtually all cells, which is reflected by the diversity of regulatory processes in which this hormone is involved. Any dysfunction of insulin signalling pathway as a result of insulin receptor gene mutations is linked with various forms of insulin resistance, including insulin resistance type A, Donohue or Rabson-Mendenhall syndrome, which differ in the level of severity. Molecular analysis of insulin receptor gene may lead to a better understanding of molecular mechanisms underlying various types of insulin resistance and help to develop a more efficient treatment. They may also be used as a powerful tool in prenatal diagnostics as well as in pregnancy planning.
