Histological analysis of the Slc27a4^wrfr/Slc27a4^wrfr mouse

mortality/aging

neonatal lethality, complete penetrance ( J:83282 )

• mice died several hours after birth

behavior/neurological

absent suckling reflex ( J:83282 )

• mice failed to suckle

decreased locomotor activity ( J:83282 )

• body movements were extremely limited in mice

digestive/alimentary system

abnormal digestive system morphology ( J:83282 )

decreased hair follicle number ( J:83282 )

• few developing hair follicles

shiny skin ( J:83282 )

• skin appeared abnormally shiny at birth

tight skin ( J:83282 )
