homeostasis/metabolism
• at 4 months of age, circulating urea levels are higher than in wild-type mice
• in female mice at 4 months of age
• at 4 months of age, mice exhibit a decrease in nonesterified fatty acids compared with wild-type mice
• moderately in male mice at 4 months of age
• increased levels are seen in phenotypic mutants (J:121470)
• strongly at 4 months of age (J:153895)
• mice have pathological plasma urea levels with 60% penetrance (phenotypic mutants) when analyzed at 3 months (2 measurements >70 mg/dl within 3-week period)
• mice exhibit increased excretion of calcium (3-fold), chloride (in males only), magnesium (males only), creatinine (males only), and urea (males only) compared with wild-type mice
• mice exhibit decreased uric acid excretion compared with wild-type mice
• urine to plasma ratios of sodium and potassium is decreased compared to in wild-type mice
• urine to plasma ratios of urea and uric acid are decreased 2- to 3-fold compared to in wild-type mice
• urine sodium/creatinine and chloride/creatinine ratios tend to be decreased in 24-hour urine and spot urine samples of phenotypic mutants
• at 3 to 4 months, mice exhibit a decrease in urine osmolality compared with wild-type mice
• water deprived mice exhibit a decrease in urine osmolality compared with similarly treated wild-type mice
• 21 hour metabolic rate is decreased compared to in wild-type mice
• minimal metabolic rate is decreased in male mice compared to in wild-type mice

renal/urinary system
N
• mice exhibit normal kidney morphology
• mice exhibit increased excretion of calcium (3-fold), chloride (in males only), magnesium (males only), creatinine (males only), and urea (males only) compared with wild-type mice
• mice exhibit decreased uric acid excretion compared with wild-type mice
• urine to plasma ratios of sodium and potassium is decreased compared to in wild-type mice
• urine to plasma ratios of urea and uric acid are decreased 2- to 3-fold compared to in wild-type mice
• urine sodium/creatinine and chloride/creatinine ratios tend to be decreased in 24-hour urine and spot urine samples of phenotypic mutants
• at 3 to 4 months, mice exhibit a decrease in urine osmolality compared with wild-type mice
• water deprived mice exhibit a decrease in urine osmolality compared with similarly treated wild-type mice
• at 3 to 4 months, mice exhibit a 1.5-fold increase in urine production compared with wild-type mice
• water-deprived mice produce 40% more urine than in similarly treated wild-type mice

skeleton
• at 6 months, total and cortical bone content in male mice is reduced at the distal femoral metaphysis and diaphysis compared with wild-type mice
• at 4 months, bone mineral content is decreased compared to wild-type mice
• at 4 months, bone mineral density is decreased compared to wild-type mice
• at 6 months, male mice exhibit a decrease in total, trabecular, and cortical bone density at the femoral diaphysis compared with wild-type mice
