Mitochondria or the power membrane of a cell are unique; they have their own DNA called mitochondrial DNA, or mtDNA.
-Mutations in mtDNA or in nuclear DNA (DNA found in the nucleus of a cell) can cause mitochondrial disorder.
– Mitochondrial diseases are chronic (long-term), genetic, often inherited disorders that occur when mitochondria fail to produce enough energy for the body to function properly.
Mitochondrial diseases can affect almost any part of the body, including the cells of the brain, nerves, muscles, kidneys, heart, liver, eyes, ears or pancreas.
-The symptoms of mitochondrial diseases can include poor growth, muscle weakness, muscle pain, low muscle tone, exercise intolerance, vision and/or hearing problems, learning disabilities, delays in development, swallowing difficulties, diarrhea or constipation, unexplained vomiting, cramping, reflux, etc.
— Notably, mitochondrial diseases are incurable and can be fatal within days or even hours of birth, if diagnosed in a newborn.
— The three-person IVF procedure is known to help eliminate mitochondrial diseases that are passed on from mother to child.
