Brief Answer:
I would recommend going in for Mitochondrial DNA Sequencing

Detailed Answer:
Thanks for asking on HealthcareMagic.

DNA sequencing for epilepsy panel is a test to identify certain mitochondrial disorders. Rather going for a more extensive 'Mitochondrial DNA Sequencing' (as in http://www.medicalneurogenetics.com/OpenTestSearch/TestsByCat.aspx?Cat=Genetic&Sub1=mtDNA&Sub2=Sequencing ) should be more informative. It will help in identifying whether the disease is primary or secondary.

About the treatment, I can say that secondary diseases are likely to be less severe and can respond better although the treatment modalities would be the same.

The average life expectancy of of primary mitochondrial disorders is less than a year. But there can be broad variations.

Muscle biopsy has its significance although it will not help in determining whether the disease is primary or secondary.

Hope that helps.

Brief Answer:
It does not matter

Detailed Answer:
Thanks for writing back.

The entire mitochondrial pool of your baby comes from the mother. So it does not really matter if you get mitochondrial DNA sequencing done for yourself (assuming that you are the mother) or your child. In any case it will indicate the possibility of being passed on if you have another child (which would be present in primary disease).

Hope it helps.
