Illumina next-generation sequencing (NGS) has the potential to transform mitochondrial DNA (mtDNA) analysis. Our technology uses sequencing by synthesis (SBS) for faster results and deeper coverage of areas of interest. It offers clearer heteroplasmy analysis and greater resolution of mixture samples.
mtDNA analysis enables coroner and medical examiner laboratories to extract genetic data from small forensic samples found in less than ideal condition. There are thousands of copies of mtDNA in every cell of the human body, but the copies found in different tissues may not be exactly the same. Referred to as heteroplasmy, these mitochondrial DNA mutations can make it difficult to confirm sample associations needed for identification in forensic investigations.
Illumina SBS can potentially transform this process, with the MiSeq FGx System capable of indexing 96 samples in one sequencing run. Its simple one-step workflow can quickly deliver results, potentially speeding up investigations.
Our next-generation sequencing (NGS) technology also provides deep coverage of areas of interest. NGS technology recently enabled research scientists to analyze human samples hundreds and thousands of years old, unlocking the secrets they contain about long vanished individuals.
Additionally, the deeper reads of Illumina NGS technology enable the accurate detection of heteroplasmy with minor allele frequencies (MAFs) > 1%. This not only results in clearer heteroplasmy analysis, but enables greater resolution of mixture samples.
For mtDNA analysis, Illumina offers a recommended workflow on the MiSeq FGX with the Nextera XT DNA Library Prep Kit.
