open-in-new
<p>Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. <a href="/facts/Mitochondria/ErHqrdJ1">Mitochondria</a> are the <a href="/facts/Organelle/vhDFnGbs">organelles</a> that generate energy for the cell and are found in every cell of the human body except <a href="/facts/Red_blood_cells/Kggpq8Jh">red blood cells</a>. They convert the energy of food molecules into the <a href="/facts/Adenosine_triphosphate/nB9bwgcU">ATP</a> that powers most cell functions. </p><p>Mitochondrial diseases take on unique characteristics both because of the way the diseases are often inherited and because mitochondria are so critical to cell function. A subclass of these diseases that have <a href="/facts/Neuromuscular_disease/jszloW1X">neuromuscular symptoms</a> are known as <a href="/facts/Mitochondrial_myopathy/wEt4uGWB">mitochondrial myopathies</a>. </p>
