Preferred Label : Diabetes insipidus, nephrogenic, 1, X-linked;
Symbol : NDI1;
CISMeF acronym : NDI;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Diabetes Insipidus, nephrogenic, type I; NDI;
Description : Nephrogenic diabetes insipidus is caused by the inability of the renal collecting
ducts to absorb water in response to antidiuretic hormone (ADH), also known as arginine
vasopression (AVP; 192340). Approximately 90% of patients are males with the X-linked
recessive form (type I), which is caused by a defect in the vasopressin V2 receptor
in renal collecting duct cells. The remaining 10% of patients have autosomal NDI (125800)
(type II), which is caused by mutations in the gene encoding the aquaporin-2 water
channel (AQP2; 107777) on chromosome 12q13 (Morello and Bichet, 2001). Neurogenic,
or central, diabetes insipidus (125700) is caused by mutation in the gene encoding
arginine vasopression, located on 20p13.;
Inheritance : X-linked recessive;
Molecular basis : Caused by mutation in the arginine vasopressin receptor-2 gene (AVPR2, 300538.0001);
Laboratory abnormalities : Hypernatremia; Decreased urine osmolality; Normal or increased levels of serum arginine vasopressin (antidiuretic hormone, 192340); No increase in urinary cyclic AMP (cAMP) in response to vasopressin or dDAVP; Abnormal extrarenal response to dDAVP (no increase in von Willebrand factor or factor
VIII);
