For many patients mitochondrial diseases are inherited conditions that run in families. This can be particularly hard to understand if the disease has arisen in a child from two apparently healthy adults.
In order to understand how Mitochondrial Disease can be passed down through future generations it is important to first understand that there are two distinct types of DNA. Errors in either of these types of DNA can cause disease.
Mitochondrial Disease can be caused by a problem in either the mitochondrial DNA or the nuclear DNA and depending on where the error has arisen, this will determine how the condition has been inherited and the risk of passing it on.
