Mitochondrial Respiratory Chain Complex I-V Nuclear Gene Deficiency Panel by Massively Parallel Sequencing

Clinical Use

Use

The Mitochondrial Respiratory Chain Complex I-V Nuclear Gene Deficiency Panel is designed to assess 43 nuclear genes associated with deficiencies in mitochondrial respiratory chain complexes I, II, III, IV, and V. These deficiencies can lead to a range of severe health issues from lethal neonatal diseases to neurodegenerative disorders appearing in adulthood. Symptoms impacting various bodily systems may manifest as extreme fatigue, muscle pain, low muscle tone, seizures, and intellectual disabilities. Early identification and accurate diagnosis are crucial for effective management and intervention, making this panel vital for patients suspected of having such mitochondrial disorders.

Special Instructions

Samples should be collected preferably by a healthcare professional using appropriate kits. Extraction and shipping methods must adhere to specified conditions to avoid sample degradation. For optimal results, the sample should arrive within 72 hours and should not be exposed to extreme temperatures prior to shipping. Contact client services for instructions on specimen submission and additional inquiries.

Limitations

The interpretation of nucleotide changes is based on the current understanding of the specific genes of interest which evolves as research progresses. This may lead to potential diagnostic errors including sample mix-ups or identification challenges due to variants interfering with analysis. Genetic variants that may not be detectable by this testing approach could also impact results. Therefore, it is recommended to communicate with genetic counselors about any concerns that may arise during the testing process, especially regarding potential errors sensitive to analysis declines.
