N normal phenotype
renal/urinary system
decreased urine osmolality ( J:61675 )
• urine osmolality is decreased to 262 milliosmol compared to 1270 milliosmol in wild-type mice
• following 36 hour water deprivation or 1-desamino-8-D-arginine-vasopressin treatment increase in urine osmolality is much less than that in wild-type mice
abnormal renal water transport ( J:61675 )
• the osmotic water permeability of the basolateral membrane of cortical collecting ducts is decreased at least 3-fold compared to wild-type mice
• expression of Aqp2 is decreased particularly in the renal cortex; however expression of Aqp1 and Aqp4 is similar to wild-type
polyuria ( J:61675 )
• about a 10-fold increase in urine output; however, kidney and urinary bladder morphology are similar to wild-type

behavior/neurological
polydipsia ( J:61675 )
• about a 10-fold increase in fluid consumption

homeostasis/metabolism
increased blood osmolality ( J:61675 )
• plasma osmolality is mildly elevated but serum electrolyte, urea, creatinine, and phosphorus levels are similar to wild-type
decreased urine osmolality ( J:61675 )
• urine osmolality is decreased to 262 milliosmol compared to 1270 milliosmol in wild-type mice
• following 36 hour water deprivation or 1-desamino-8-D-arginine-vasopressin treatment increase in urine osmolality is much less than that in wild-type mice
