Forensic Genetic Approaches for Identification of Human Skeletal Remains by Angie Ambers, 2023
Unidentified human remains (UHRs) are associated with tragic events such as homicides, fires, terrorist attacks, natural disasters, war conflicts, genocide, airline crashes, human rights violations and forced disappearances under oppressive totalitarian regimes. In these situations, extensive damage to soft tissues often precludes the use of such biological samples in the identification process; in contrast, bone material is structurally resilient and is often the most viable (or the only available) types of sample for DNA testing. DNA recovered from bone can be very degraded and may exist in Low quantities due to the effects of human decomposition, environmental exposure, and the passage of time. The complexities of bone microstructure, its nonuniform patterns of diagenesis, and physical rigidity make skeletal remains one of the most challenging sample types for DNA testing. Specialized knowledge, equipment, and training are crucial to maximize success. Forensic Genetic Approaches for the Identification of Human Skeletal Remains: Challenges, Best Practices, and Emerging Technologies provides comprehensive coverage of established bone processing techniques and an overview of available DNA technologies for both contemporary casework and historical/archaeological investigations. The book focuses primarily on the use of DNA for direct identification or kinship analyses, but also highlights interdisciplinary approaches. Among the broad range of topics covered include: Detailed description of proper facilities design, contamination prevention measures, and specialized equipment needed for skeletal remains processing, Guidance on selection of optimal skeletal elements for DNA recovery, cleaning and preparation of bone samples for DNA testing, physical processing techniques (sectioning, pulverization), and DNA extraction methods, Overview of genetic markets available for identification of human skeletal remains, including autosomal short tandem repeats (STRs), Y-chromosome STRs, X-chromosome STRs, mitochondrial DNA (mtDNA), insertion/deletions (INDELS), ancestry-informative single nucleotide polymorphisms (SNPs), phenotype-informative SNPs, and identity-informative SNPs, Discussion of various platforms used to analyze DNA extracted from skeletal remains, including capillary electrophoresis (CE) instrumentation, massively parallel sequencing (MPS) systems, and field-deployable Rapid DNA equipment, Description of available databases and bioinformatic tools for genetic data analysis, including the Mass Fatality identification System (M-FISys), Overview of complementary disciplines often used in concert with genetic data to make positive identifications, including forensic anthropology, odontology, forensic art/sculpting (facial reconstructions), and genetic genealogy
