Washington : A new study has revealed that there are greater rates of the mitochondrial DNA variants in children born to older mothers, as well as in the mothers themselves, which cause more than 200 diseases and contribute to others such as diabetes, cancer, Parkinson’s disease, and Alzheimer’s disease, reports ANI.

According to the study, many mitochondrial diseases affect more than one system in the human body, including organs that require a lot of energy, including the heart, skeletal muscle, and brain. They are devastating diseases and there is no cure, so our findings about their transmission are very important.

The discovery of a “maternal age effect” by a team of Penn State scientists that could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells — and the transmission of these mutations to children — could provide valuable insights for genetic counselling.
