Small size and retarded hair growth in Oatrhg/Oatrhg mice

nervous system
• somewhat shortened and disorganized at 12 months of age

mortality/aging
• breeding heterozygotes with homozygotes yields only 41% mutant offspring rather than the predicted 50%

growth/size/body
• although normal size at birth, homozygotes are smaller than littermates shortly thereafter then begin to catch up in size at 4 weeks of age

pigmentation
• at one week of age homozygotes have no pigment, and older homozygotes have white at the tips of the hair
• at 12 months of age the retinal pigment epithelium shows degeneration with irregular swelling and frequent doming, with occassional migration of retinal pigment epithelial cells into the outer segment layer

homeostasis/metabolism
• plasma ornithine is increased to approximately 1000 uM

vision/eye
• somewhat shortened and disorganized at 12 months of age
• at 12 months of age the retinal pigment epithelium shows degeneration with irregular swelling and frequent doming, with occassional migration of retinal pigment epithelial cells into the outer segment layer
• cataracts are found 2 month and 3.5 month old homozygotes

hearing/vestibular/ear
N
• two of two homozygotes assessed show normal auditory brain stem response

integument
• at one week of age homozygotes have no pigment, and older homozygotes have white at the tips of the hair
• at two weeks of age homozygotes still have no hair and hair begins to grow in at 3 weeks of age
• after 1 month of age the fur has a ruffled appearance due to growing in different directions
• follicular dysplasia

integument

growth/size/body
• delayed growth by 7 days of age, which can be ameliorated by i.p. injection of arginine

nervous system
• somewhat shortened and disorganized at 12 months of age

homeostasis/metabolism
• plasma ornithine is increased to approximately 1200 uM

pigmentation

mortality/aging
• only 70% of compound heterozygotes survive to weaning without arginine supplementation, and 45% of compound heterozygotes die before one year

vision/eye
• somewhat shortened and disorganized at 12 months of age
