: A group of genetic disorders that result in progressive muscle weakness due to abnormalities in muscle proteins, including actin and myosin. : Diseases of the heart muscle that can affect the contractile function of actin and myosin in cardiac muscle cells. : An autoimmune disorder that affects the neuromuscular junction, potentially impacting actin and myosin interaction.
