mortality/aging
• many die by 8 weeks of age
|
behavior/neurological
abnormal gait
(
J:96441
)
• at 4-5 weeks of age mice begin to hobble about their cage
|
• between 5 and 8 weeks of age the mutants develop rear limb paralysis
|
growth/size/body
• at 4-5 weeks of age when the mutants appear smaller than their control littermates
|
limbs/digits/tail
• complete fractures of the femur, in particular at the knee near the epiphysis and beneath the growth plate
|
skeleton
• complete fractures of the femur, in particular at the knee near the epiphysis and beneath the growth plate
|
• very low amounts of mineral were detected in the overall mutant skeleton compared to controls
|
• between 4 and 8 weeks of age mice show thin cortical bone; in particular, the long bones were affected; forelimbs and spine were less affected than the rear legs
|
• absence of trabeculae; forelimbs and spine were less affected than the rear leg
|
• mineralized callus; extensive at the fracture sites
|
vision/eye
• cataracts on both eyes were noted; however, this is a characteristic of the background strain and may not be due to the sfx mutation
|
• rosettes and wavy outer nuclear layer of retinas; this phenotype may also be characteristic of the background strain
