Aw-J/Aw-J EdaTa-6J/Y male.

endocrine/exocrine glands
• absent preputial glands
(J:86628)
(J:99510)

growth/size/body
• mutants have 2-3 molars compared to 3 in wild-type
• at 5 months of age, weight is 77% that of wild-type

craniofacial
• mutants have 2-3 molars compared to 3 in wild-type

vision/eye
• more than 80% show ocular surface inflammation (limbitis, conjunctivitis, blepharitis)
• increased susceptibility to corneal inflammation is seen from 8 weeks of age in males housed in convention housing but not in mice in a pathogen-free facility
• several males have abundant mucus in the eye at 23 weeks of age
(J:86628)
(J:99510)
• more than 80% develop progressive corneal lesions beginning at 4-9 weeks of age such as neovascularization, keratitis, ulceration, and keratinization
• corneal neovascularization begins at 8-9 weeks of age and eventually leads to vision loss
• mutants exhibit a progressive corneal epithelia defect starting at 8-9 weeks of age and develop epithelial edema and acanthosis
• 9 of 15 males have grossly visible white or white and red central, elevated corneal opacities at around 23 weeks of age
• narrowed palpebral fissures
• thickened eyelid margins and loss of hair along the eyelid margins
• blindness by 9 months of age (J:86628)
• develop severe blinding lesions in the cornea over time (J:99510)

immune system
• more than 80% show ocular surface inflammation (limbitis, conjunctivitis, blepharitis)
• increased susceptibility to corneal inflammation is seen from 8 weeks of age in males housed in convention housing but not in mice in a pathogen-free facility

limbs/digits/tail

pigmentation
• hair coat is yellowish

reproductive system
• absent preputial glands

renal/urinary system
• absent preputial glands

cardiovascular system
• corneal neovascularization begins at 8-9 weeks of age and eventually leads to vision loss

integument
• absent preputial glands
• males have more medium-length hair, however because they lack guard and zigzag hairs the overall number of hair follicles is the same
• hair coat is yellowish
• mutants have a bald patch behind the ear and absent hair on the tail
• hair coat is short and thin
• do not exhibit skin ridges on the tail as in wild-type
