mortality/aging

postnatal lethality, incomplete penetrance ( J:116740 )

• slight but significant reduction in survival

craniofacial

abnormal oral mucosa morphology ( J:116740 )

• mild lymphocytic infiltration in the submucosa

oral leukoplakia ( J:116740 )

• primarily on the tongue but also found on the palatal and esophageal mucosa

• mucosal thickening and cytolysis of the spinous layer within lesions; however, the basal cell layer is intact

abnormal tongue morphology ( J:116740 )

• normal architecture is absent and the tissue is friable

digestive/alimentary system

abnormal oral mucosa morphology ( J:116740 )

• mild lymphocytic infiltration in the submucosa

oral leukoplakia ( J:116740 )

• primarily on the tongue but also found on the palatal and esophageal mucosa

• mucosal thickening and cytolysis of the spinous layer within lesions; however, the basal cell layer is intact

abnormal tongue morphology ( J:116740 )

• normal architecture is absent and the tissue is friable

growth/size/body

abnormal oral mucosa morphology ( J:116740 )

• mild lymphocytic infiltration in the submucosa

oral leukoplakia ( J:116740 )

♀	phenotype observed in females

N	normal phenotype

digestive/alimentary system

oral leukoplakia ( J:116740 )

• on the tongue

• milder than in homozygous mice

abnormal tongue morphology ( J:116740 )

• thickened lingual mucosa with evidence of inter-papillar cytolysis

pigmentation

diluted coat color ( J:116740 )

• bright coat color and light brown pigment in all hairs rather than the normal dark brown/black

• difference in coat color is most visible around 4 weeks of age

craniofacial

oral leukoplakia ( J:116740 )

• on the tongue

• milder than in homozygous mice

abnormal tongue morphology ( J:116740 )

• thickened lingual mucosa with evidence of inter-papillar cytolysis
