machinery can generate toxic by-products --
"oxygen free radicals" -- that can chemically damage surrounding molecules,
including mtDNA. Damaged mtDNA causes the production of faulty or decreased
OX-PHOS machinery, which then can increase the generation of oxygen free
radicals, and so a vicious cycle is triggered that ultimately leads to a
reduced energy supply ATP. The amount of damaged mtDNA thus is an inverse
measure of cellular health: the less damage the healthier and the more damage
the less healthy a cell is.
Transgenomic has specialized in the molecular diagnostics of mitochondrial
disorders including whole mitochondrial genome sequence and pathogenic point
mutation analysis, as well as assessment of nuclear genes associated with
mitochondrial function, such as DNA polymerase gamma (POLG). In addition to
the mtDNA damage assay, Transgenomic is developing other tests to assess mtDNA
copy number and deletion.
