Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells .
Mitochondrial myopathy literally means mitochondrial muscle disease, muscle disease caused by mitochondrial dysfunction. The mitochondrion is the primary producer of energy in nearly all cells throughout the body. The exception is mature erythrocytes (red blood cells), so that they do not use up the oxygen that they carry.
As of 2019, about 4.9 million people globally were living with an inflammatory bowel disease (IBD) such as Crohn’s disease. Scientists are still unclear as to the exact cause of Crohn’s ...
Mitochondria. Pearson syndrome is a mitochondrial disease caused by a deletion in mitochondrial DNA (mtDNA). [3] An mtDNA is genetic material contained in the cellular organelle called the mitochondria. Depending on the tissue type, each cell contains hundreds to thousands of mitochondria. There are 2–10 mtDNA molecules in each mitochondrion.
Mitochondrial diseases range in severity from asymptomatic to fatal, and are most commonly due to inherited rather than acquired mutations of mitochondrial DNA. A given mitochondrial mutation can cause various diseases depending on the severity of the problem in the mitochondria and the tissue the affected mitochondria are in.

The disease presents in childhood, but often goes unnoticed for decades. [2] [4] [5] Unlike typical mitochondrial diseases caused by mitochondrial DNA (mtDNA) mutations, MNGIE is caused by mutations in the TYMP gene, which encodes the enzyme thymidine phosphorylase.
Mitochondria dysfunction is thought to be involved in Parkinson's disease pathogenesis. In spontaneous, usually aging related Parkinson's disease (non-genetically linked), the disease is commonly caused by dysfunctional mitochondria, cellular oxidative stress, autophagic alterations and the aggregation of proteins.
