What organelle does pearson syndrome affect? Pearson syndrome is a mitochondrial disease caused by a deletion in mitochondrial DNA (mtDNA). 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.
What functions are disrupted by Pearson syndrome? In people with Pearson syndrome, the pancreas does not work as well as usual. The pancreas produces and releases enzymes that aid in the digestion of fats and proteins. Reduced function of this organ can lead to high levels of fats in the liver (liver steatosis).
How does Pearson syndrome affect the mitochondria? Pearson syndrome is usually caused by missing pieces — called deletions — of a part of the mitochondrial DNA. Changes in mitochondrial DNA make it hard for the cell to make energy. Most cases of Pearson syndrome occur by mistake during the time when the egg or sperm were being made, also called de novo mutation.
Who does Pearson syndrome affect? Pearson syndrome affects many parts of the body but especially the bone marrow and the pancreas. Pearson syndrome affects the cells in the bone marrow (hematopoietic stem cells) that produce red blood cells , white blood cells , and platelets .
