Confused

Hi all,

I am Mom to an 11 yr old son. He has multiple health issues and we have recently done a muscle biopsy and skin biopsy looking for mito. His prior bloodwork showed abnormalities, but not conclusive. The muscle biopsy was fresh and showed a mild increase ni mitochondria, Type II fiber atropy, mild and Type I fiber predominance. The mito were non-uniform and mal-oriented.Lipofiscin granules were seen. It was noted on the path report that lipofiscin granules are unusual in a child this age.The electron Transport testing showedno deficiency in mito electron transport chain enzymes. The activities of several respiratory chain complexes are reduced.The skin biopsy was examined to check for mito beta oxidation and was found to be normal. Waiting for doctor input. Does anyone with more experience know what this all means?? Any input is welcome! Thanks
