Leigh syndrome is a case of mitochondrial disease frequently ascribed to mitochondrial respiratory deficiency in muscles and in a wide variety of tissues. The clinical manifestation of this disease is extremely heterogeneous. It depends on a severity of oxidative phosphorylation (OXPHOS) damage and on need of different organs and tissues in ATP. Very often in such cases it is difficult to predict a causative mutation.
In our laboratory we perform mitochondrial genes sequence analysis (in nuclear and mitochondrial DNA) of patients with Leigh and Leigh-like disease to determine a mutation. But mostly these patients are classified to a group with mitochondrial disorders just by phenotype features, not correctly sometimes. Thus, it would be highly important for us to apply a high-resolution respirometry (HRR) measurement on muscle biopsy to prove a mitochondrial dysfunction as a cause of the disease. Also this approach can help to avoid a needless analysis on patients with intact mitochondria.
Another potential application of HRR in our research is measurement of respiration in fibroblast cell cultures of patients with defined rare mutation. As nowadays there is not a unique drug for such patients, they are usually subjected to a symptomatic treatment of various substances. We plan to treat fibroblast with different agents (e.g. antioxidants) to find the most effective one for every mutation individually.
Therefore the HRR approach will improve the quality of our investigation.
