Functional and structural assays, including oxygen consumption rate, ATP synthesis, reactive oxidative species (ROS) production and electron microscopy, indicated that mitochondrial damages were present in the lymphoblastoid cells carrying 2336T&gt;C mutation. Our findings provide a new insight in the pathogenesis of HCM.
