digestive/alimentary system
• the zymogenic cells of the glandular stomach are severely decreased
• increase in parietal cells

reproductive system
• 60% of E7.5 mutants have low counts of primordial germ cells while some E13.5 embryos, both males and females, lack primordial germ cells
• 2/7 of males have abnormal reproductive tracts
• testis cords of affected males are disorganized and depleted of primordial germ cells
• 2/7 of males have small testes
• intercrosses between homozygous mutants are less productive than those between heterozygotes

cellular
• embryonic fibroblasts display stronger intercellular contacts, an accumulation of cortical actin and a decrease in stress fibers compared to wild-type MEFs
• 60% of E7.5 mutants have low counts of primordial germ cells while some E13.5 embryos, both males and females, lack primordial germ cells

endocrine/exocrine glands
• the zymogenic cells of the glandular stomach are severely decreased
• increase in parietal cells
• testis cords of affected males are disorganized and depleted of primordial germ cells
