N normal phenotype
homeostasis/metabolism
N
• female mice exhibit normal serum protein (total protein, albumin, and total iron binding capacity) levels
• at 14 months of age
• slight with increased transferrin saturation
• however, iron levels are normal in the brain and erythropoiesis organ
• mild delay in glucose clearance in female, but not male mice

nervous system
• impaired in the cerebellar cortex
• in the medulla oblongata
• reduced dopamine positive neuroaxonal fibres in the substantia nigra
• progressive with eosinophil spheroids and swollen structures in the basal ganglia, thalamus, cerebral cortex, medulla oblongata, spinal cord, and deep cerebellar nuclei

vision/eye
• in female, but not male, mice
• in some mice

behavior/neurological
• at 20 months
• increased falls on a balance beam and longer time to traverse a beam ladder with increased hindpaw slips
• however, forepaw slips rate is normal
• increased distance traveled

growth/size/body

hearing/vestibular/ear
• progressive starting at 17 months in a click-box test

hematopoietic system
• female mice exhibit normal leukocyte and erythrocyte counts along with normal hemoglobin levels and hematocrit levels
• MP:0002642

pigmentation
• in the retina
• however, no lipofuscin accumulation in the brain

cellular
• reduced complex I activity when normalized to citrate synthase activity in the brain
• however, mice exhibit normal citrate synthase activity and normalized respiratory chain complex activity in the heart
