Disease caused by mitochondria
WebHeart disease, kidney problems, and difficulty breathing can also occur in people with this disorder. Mitochondrial DNA-associated Leigh syndrome is a subtype of Leigh syndrome and is caused by changes in mitochondrial DNA. Genetic changes in at least 11 mitochondrial genes have been found to cause mtDNA-associated Leigh syndrome. WebMitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function. Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation. Oxidative phosphorylation is a process that uses oxygen and simple sugars to create adenosine triphosphate (ATP), the cell's main energy source.
