muscle
abnormal muscle physiology ( J:132177 )
• muscle fibers exhibit a 31.6% decreased peak amplitude calcium ion transient following a single action potential stimulation compared to in wild-type mice
• muscle fibers exhibit a prolonged rising phase of calcium ion transient following a single action potential stimulation compared to in wild-type mice
• however, calcium ion resting levels are normal
