pigmentation
|
• the first coat is a uniform light tan
• at the first molt, the body hair becomes lighter, and the ears, nose, tail and scrotum become dark
• mutants treated with nitisinone show increased pigmentation in areas of new hair growth
|
|
• mutants exhibit iris transillumination that is not observed in wild-type mice
• mutants treated with nitisinone show increased pigmentation in the irides
|
|
• eyes are minimally pigmented and appear red

pigmentation
|
• the fully grown juvenile coat is pale tan with little evidence of darkening of extremities except the tail
|
|
• pink eye color of the new born darkens to ruby-colored by weaning
|
vision/eye
|
• pink eye color of the new born darkens to ruby-colored by weaning
|
integument
|
• at one week of age affected mice are slightly darker than albinos, particularly on tail
• the body coat color may range from unifrom to slightly lighter dorsal and ventral across the shoulders, darker toward the tail where a very dark ring of body fur develops adjacent to the tail
• at first molt the nose, ears, tail, and scrotum but not the feet become considerably darker; the rest of the body becomes lighter
• dark hair on the nose extends back to the anterior border of the eyes
|
|
• the fully grown juvenile coat is pale tan with little evidence of darkening of extremities except the tail
