From OMIMNephrogenic diabetes insipidus (NDI) is caused by the inability of the renal collecting ducts to absorb water in response to antidiuretic hormone (ADH), also known as arginine vasopressin (AVP; 192340). Approximately 90% of patients are males with the X-linked recessive form, type I (NDI1; 304800), which is caused by mutation in the gene encoding the vasopressin V2 receptor (AVPR2; 300538). The remaining 10% of patients have the autosomal form, type II (NDI2), caused by mutation in the AQP2 gene (Morello and Bichet, 2001).
Neurogenic, or central, diabetes insipidus (CDI; 125700) is caused by mutation in the gene encoding arginine vasopressin, located on 20p13.
http://www.omim.org/entry/125800 From MedlinePlus GeneticsArginine vasopressin resistance (previously called nephrogenic diabetes insipidus) is a disorder of water balance. The body normally balances fluid intake by releasing excess fluid in urine. However, people with arginine vasopressin resistance produce an excessive amount of urine (polyuria), which depletes the amount of water in the body. This water loss also leads to excessive thirst (polydipsia).
Affected individuals can quickly become dehydrated if they do not drink enough water. Dehydration can cause dizziness and fatigue. Prolonged dehydration can lead to confusion, low blood pressure, seizures, and coma. People with arginine vasopressin resistance often develop high levels of sodium in the blood (hypernatremia) due to dehydration. Repeated cycles of dehydration can cause long-term health problems, particularly in children.
Arginine vasopressin resistance can be either acquired or familial. The acquired form can occur at any time during life. The familial form usually become apparent within the first year of life, though in some cases they develop in adolescence or early adulthood.
Researchers have recommended using the condition name arginine vasopressin resistance because the previous name, nephrogenic diabetes insipidus, was often confused with a much more common disorder called diabetes mellitus. Arginine vasopressin resistance and diabetes mellitus are separate disorders with different features, causes, and treatment.
Infants with familial arginine vasopressin resistance tend to have problems feeding and gaining weight (failure to thrive). They may also be irritable and experience fevers, diarrhea, and vomiting. Recurrent episodes of dehydration can lead to slow growth and delayed development. If the condition is not well-managed, it can damage the bladder and kidneys leading to pain, infections, and kidney failure. With appropriate treatment, affected individuals usually have few complications and a normal lifespan.
