Comprehensive mtDNA Analysis by Massively Parallel Sequencing (MitoNGSSM)
Test Information: Confirmation of Clinical Diagnosis. Evaluation of the entire mitochondrial genome for point mutations and deletions.
Test Details
Test Code: 2055
Special Notes: Unlike traditional direct sequence analysis, massively parallel sequencing provides thousands of reads for each nucleotide position of the entire 16,569 bp mitochondrial genome. The high-throughput sequence data generated by massively parallel sequencing enables a more accurate quantification of low-level mtDNA heteroplasmy sequence changes and detection of deletions with breakpoints.

The detection threshold of massively parallel sequencing analysis for heteroplasmic mitochondrial DNA point mutations is approximately 1.5% for the Illumina HiSeq 2000 platform. If targeted sequencing analysis is required for matrilineal family members, please order test code #3056 (targeted Sanger sequence, no heteroplasmy quantification), or test code #2056 (targeted massively parallel sequencing with heteroplasmy quantification).
The following subsets of MitoNGS can be ordered separately:

- Advanced mtDNA Point Mutations and Deletions by Massively Parallel Sequencing (BCM-MitomeNGSSM) (#2010)
- Mitochondrial Nonsyndromic Hearing Loss and Deafness Mutation Panel (#3030)
