seeking feedback on DNA blood test

[Guest guest]

I've finally received a callback from my " neurologist with apparent interest

in mito " at MGH. His office left a message about the test they want to do,

so I wasn't able to ask any questions yet. BTW I had NO idea how many calls

and delays would be required, before I could get this simple next step

rolling.

What they want to do, they called it " mitochondrial myopathy DNA evaluation "

and then said this is " blood work " . I have a definite diagnosis of MSL

which is known to have mito origins (and for which SOME patients have

various KNOWN particular mtDNA mutations). I have not yet had any DNA tests

or biopsies. FWIW they also want to do an EMG (presumably far more involved

than one I had three years ago).

Before I call them back on Monday to schedule this test, does anyone have

any specific questions I should ask, or " suggestions " as to which specific

DNA tests should be done, or preferred labs to do the testing (I think they

do at least some of this in-house, but I don't really know)? I have the

feeling that I will have little input on any of this, but it's worth a try.

Presumably the results may lead to further testing.

Thanks in advance
