Initially described as distinct entities, they have subsequently been found to be caused by mutations in the insulin receptor gene (INSR). They are characterized by intrauterine and postnatal growth restriction, paucity of adipose tissue, overgrowth of many soft Y-27632 cost tissues including skin, hair and teeth, and characteristically coarse facial features, as well as severely abnormal find more glucose homeostasis and extreme insulin resistance. DS denotes the more severe end of the symptom spectrum and is often associated with death in the first year of life. It was first described by Donohue in 1948 [1], and termed ��leprechaunism�� in 1954 [2]. RMS, originally described in 1956 [3], generally is taken to encompass slightly less severely affected patients, although the distinction between DS and RMS is not strictly defined. RMS also features linear growth impairment, soft tissue overgrowth, and coarse features. The severe insulin resistance leads to hyperinsulinism with pancreatic ��-cell decompensation, diabetes, hyperglycemia and ultimately ketoacidosis, usually towards the end of the first or in the second decade, as well as hyperandrogenism. Early mortality due to advanced complications of diabetes is common [4]. A more common but less severe phenotype, often called type A insulin resistance, features insulin-resistant diabetes and hyperandrogenism that usually is identified peri- or postpubertally. In most bepotastine causes this is accounted for by dominant negative heterozygous mutations in the tyrosine kinase domain of the receptor, however a minority of cases are caused by biallelic, presumably less deleterious, ��-subunit mutations [4]. The INSR is expressed throughout the nephron [5,6], but little is known about its precise role. In vivo perfusion experiments in rabbits showed a positive effect of insulin on proximal tubular sodium reabsorption [7], yet the absence of insulin signaling in mice with kidney-specific deletion of INSR is also associated with enhanced sodium reabsorption and consequent elevated blood pressure (BP) [8].
