Next generation sequencing: Forensic applications and policy considerations

Abstract

AbstractNext generation sequencing (NGS) or massively parallel sequencing (MPS) is a high‐throughput technology that can be used to analyze DNA and RNA molecules with greater sensitivity, scalability, and speed than traditional Sanger sequencing. NGS systems are slowly gaining popularity in forensic science and may eventually become the future of forensic DNA analysis. The data generated can be utilized to conduct an array of forensic biology analyses such as short tandem repeats (STR) profiling, forensic genetic genealogy, predictive DNA phenotyping, and more. However, the adoption of NGS for forensic casework is associated with a lot of ethical, social, and legal concerns. This article provides a comprehensive review of NGS systems, data analysis, and forensic applications. It also provides policy considerations that aim to reduce harm and bias, while promoting informed consent, standardization, transparency, and accountability.This article is categorized under: Forensic Biology > Interpretation of Biological Evidence Forensic Biology > Ethical and Social Implications Forensic Biology > Forensic DNA Technologies
