vision/eye
• some homozygous mutants exhibit corneal opacity
|
• the eyes of mutant mice appear reduced in size

craniofacial
hearing/vestibular/ear
integument
• from about three weeks of age, mice heterozygous for this mutation exhibit progressive hair loss
• mutant mice eventually become entirely hairless, except for the vibrissae and snout hairs; the hair loss may be more severe in homozygous than in heterozygous mutants
• Background Sensitivity: mutant mice of the coisogenic C57BL/6J strain backgroiund are bare by 4 months of age; hair loss is relatively delayed in a mixed C3H/C57BL/6J background

coarse hair
(

)
• as the coat thins, the remaining hairs gradually appear coarser
|
• before three weeks of age, the hair coats of mutant mice appear normal; however, their skin is visibly wrinkled beneath the fur
