N normal phenotype
mortality/aging
premature death ( J:142595 )
• unlike Lama5tm1Jhm homozygotes, mice several month before dieing from kidney disease

nervous system
abnormal neuromuscular synapse morphology ( J:142595 )
• maturation of postsynaptic neuromuscular junctions (NMJs) is delayed compared to in wild-type mice
• however, maturation of presynaptic NMJs is normal

renal/urinary system
abnormal renal/urinary system physiology ( J:142595 )
• mice die from kidney disease
