The neurologist called me with the anticipated results today. Evidently, KayTar has more mitochondria in her cells than is typical, which may point to mitochondrial dysfunction (mitochondria are the energy factories of the cells. if your factories aren't able to produce enough to keep up with demand, what do you do? build more factories!) but doesn't mean much diagnostically speaking. The neurologist is ordering further tests on the muscle biopsy, so once again we'll wait and hope for answers, knowing they probably won't be found.
