Abstract

En 中文

• URMD-Seq enables accurate detection of ultra-rare mtDNA variants at very low allele frequency not detected by classical next-gen sequencing. • Unique molecular identifier-based error suppression distinguishes true variants from PCR and sequencing artefacts. • The method is well suited for epidemiological studies with moderate to large sample size. • Analysis parameter can be customized, and their optimization balances false-positive suppression and signal retention.
