Brief Summary:Heterozygous, de novo variants in KIF5B are identified in 4 individuals with osteogenesis imperfecta. Studies of these KIF5B variants in C. elegans and cell models reveal the disease-causing mechanism. KIF5B seems important for intracellular trafficking and mTOR signaling to maintain skeletal homeostasis.Several years after the description of the last new osteogenesis imperfecta (OI)-related gene, the authors repo...
