Frequency:  uncommon, with a prevalence of 1 case per   25,000 population (as in the United States).

 Signs and symptoms:  polydipsia  : extreme thirst (especially for                 cold or ice water) 

  polyuria  : excretion of large amounts of              severely diluted urine

Central (neurogenic) DI:  decreased secretion of  antidiuretic hormone  (ADH) in the brain.  

Nephrogenic DI:  inability of the kidney to respond normally   to ADH.

Acquired (most common)

Hereditary:Type Gene Locus

NDI 1 AVPR2

(a) X-linked genetic defect.(b) causes the arginine vasopressin      receptor V2 receptor in the      kidney to not function correctly. 

NDI 2(rare)

AQP2

(a) Gene map locus : 12q13(b) mutation in the aquaporin 2 gene 

impede the normal function of the kidney water channel

AQP2

The mutation of AQP2 gene causes:  1. misfolding of mutant aquaporin-2 water channels  2. unsuccessful AQP2 transition in the ER
