not a standard blood test....why would you get it?

The current thinking is that most mitochondrial diseases are the result of one or more complex inheritance patterns. Most mitochondrial diseases are the result of mutations (changes) in DNA located in the nucleus of the cell. Only mitochondrial disorders caused by mutations in the mitochondrial DNA (a specific structure in living cells, located outside the nucleus) are inherited exclusively from mothers.

Another source of mitochondrial disorders that affects a large percentage of patients is poorly functioning mitochondria that become that way because of:

  • another disease process (including other chromosomal disorders)
  • exposure to toxins or viruses
  • other inherited genetic mutations that are not disease-causing until "triggered" by some other genetic factor
