unknown mitochondrial mutation. hi my son [NAME]  is now almost 4 and was diagnosed with a mitochondrial mutation at about 10 months. we have no treatment other then some vitamins and carnitine and hes got really poor tone low energy pain and behavioral issues. He also has sleep  apnea and a history of tubes and now hearing imapairment which we are investigating. He has gerd and high piruvate levels and lactic acid levels almost every time they are drawn. His mutation has "never been seen before". Im wondering if you can help in any way. My twin sister has mito she was diagnosed through a muscle biopsy but not the same mutation as [NAME] i had a biopsy with a negative result as my insurance won't cover the genetic blood pannel i really need so for me its inconclusive, im wondering if you have ever heard of this mutation or are willing to look into it  Heres a little snipit of one of his diagnosis "heteroplasmic mutation in the ATP6 gene, c8899A (L M), GERD, epsisodes of cyanosis and an abnormal 6-channel study suggesting apnea. He has lactate and pyruvate elevations in addition to a mtDNA mutation consistant with a mitochondrial disorder." If you can help in any way we would be eternally greatful! thanks so much for taking the time to read this.

Summarized question: Where can I find inforrmation on mitrochondrial mutations, including diagnosis, symptoms and treatments?
