growth/size/body
• body weight begins to increase between 8 - 12 weeks of age
|
• adiposity indices are increased 3-fold and 2-fold in females and males, respectively, compared to littermate controls
|
• at 6 months of age, kidneys are enlarged
|
• at 6 months of age, kidneys are about twice the weight of normal kidneys
|
adipose tissue
• the amount of white fat is increased particularly in the subcutaneous and reproductive regions
|
homeostasis/metabolism
• plasma glucose levels are increased to over 250 mg/dl in males after 16 weeks of age; however in younger males and in females plasma glucose levels are only slightly elevated
|
• hyperinsulnemia develops in males and females between 8 and 12 weeks of age
|
• at 20 weeks of age moderately increased plasma total cholesterol levels are seen; however plasma triglyceride levels are similar to controls
|
albuminuria
(
J:100403
)
• micro- and macro-albuminuria is seen in males but not females at 24 weeks of age
|
crystalluria
(
J:100403
)
• calcium oxalate diphosphate crystals are frequently observed in urine sediments
|
hearing/vestibular/ear
• in mice 8 months of age or older auditory brainstem response thresholds are increased to greater than 55 db sound pressure level; however morphology of the structures of the inner and middle ear appear normal
|
vision/eye
• at 24 weeks of age loss of cell bodies in the outer nuclear layer reduces it from 10 to 6 layers and the inner and outer segments are shortened
• at 24 weeks of age, mislocalization of rhodopsin to the outer nuclear layer is seen
|
• at 9 weeks of age reduced cone b-wave responses are observed and by 24 weeks of age 33% of mutants show significantly reduced b-wave amplitudes
|
reproductive system
• variable atrophy of the seminiferous tubules from severe vacuolization with no secondary spermatocytes to testes that only lacked mature sperm is seen
|
small gonad
(
J:100403
)
• hypogonadism is seen in all homozygotes
|
renal/urinary system
• at 6 months of age, kidneys are enlarged
|
• at 6 months of age, kidneys are about twice the weight of normal kidneys
|
albuminuria
(
J:100403
)
• micro- and macro-albuminuria is seen in males but not females at 24 weeks of age
|
crystalluria
(
J:100403
)
• calcium oxalate diphosphate crystals are frequently observed in urine sediments
|
• at 24 weeks of age, interstitial inflammation and vacuolization is seen suggesting degeneration of the tubules
|
• at 6 months of age, the proximal tubules are dilated and contain eosin-positive, flocculent material
|
liver/biliary system
• macrovesicular lipid deposits are seen in 24 - 30 week old mice
|
• microvesicular lipid deposits are seen in 24 - 30 week old mice
|
cellular
N |
• cilia assembly and morphology of cilia in the nasal epithelium, renal tubules, and retina are normal
|
immune system
• at 24 weeks of age, interstitial inflammation and vacuolization is seen suggesting degeneration of the tubules
|
endocrine/exocrine glands
• partial degranulation of islet beta cells is seen compared to wild-type mice
|
• islets are severely enlarged and hyperplastic
|
• variable atrophy of the seminiferous tubules from severe vacuolization with no secondary spermatocytes to testes that only lacked mature sperm is seen
