N normal phenotype
• mice die within 10 weeks of birth likely due to ileus

digestive/alimentary system
• unlike in wild-type, mice exhibit pronounced spindle-shaped cell proliferations in the lower esophagus, stomach, proximal duodenum and colon with more severe proliferations in the pylorus and proximal colon resulting in luminal narrowing
• however, small intestines are normal
• mice exhibit black lesions at the lower esophagus due to melanocyte aggregations in muscularis propria and adventitia
• mice often exhibit a distended ileum due to luminal narrowing
• mice often exhibit a distended stomach due to luminal narrowing

• mice exhibit a large whitish, linear tumor that almost entirely replace the cecum
• mice develop cecal tumors at any age

reproductive system
• unlike mice carrying other alleles of this gene, mice exhibit normal spermatogenesis
