Shorter small intestines in mgi:5563563/mgi:5563563 mgi:2653286/0 and mgi:5563563/mgi:5563564 mgi:2653286/0 mice

mortality/aging
neonatal lethality, incomplete penetrance ( J:204964 )
• fewer than expected mice are born
prenatal lethality, incomplete penetrance ( J:204964 )
• fewer than expected mice are born

digestive/alimentary system
abnormal small intestine morphology ( J:204964 )
• shorter than in control mice

muscle
impaired smooth muscle contractility ( J:204964 )
• induced by high KCl, carbachol or ET1 in the colon
• however, the L-type calcium channel inhibitor diltiazem blocks contractile responses to high KCl

growth/size/body
growth/size/body region phenotype ( J:204964 )
N
• mice exhibit normal body weight
