Recommendations of the DNA Commission of the International Society for Forensic Genetics (ISFG) on short tandem repeat sequence nomenclature. Forensic Sci Int Genet 2024; 68:102946. [PMID: 39090852 DOI: 10.1016/j.fsigen.2023.102946] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 10/14/2023] [Indexed: 08/04/2024]
Abstract
The DNA Commission of the International Society for Forensic Genetics (ISFG) has developed a set of nomenclature recommendations for short tandem repeat (STR) sequences. These recommendations follow the 2016 considerations of the DNA Commission of the ISFG, incorporating the knowledge gained through research and population studies in the intervening years. While maintaining a focus on backward compatibility with the CE data that currently populate national DNA databases, this report also looks to the future with the establishment of recommended minimum sequence reporting ranges to facilitate interlaboratory comparisons, automated solutions for sequence-based allele designations, a suite of resources to support bioinformatic development, guidance for characterizing new STR loci, and considerations for incorporating STR sequences and other new markers into investigative databases.

Forensic Sci Int 2023; 348:111729. [PMID: 37196610 DOI: 10.1016/j.forsciint.2023.111729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/11/2023] [Accepted: 05/12/2023] [Indexed: 05/19/2023]
Abstract
Next-generation sequencing (NGS) technology has shed light on every aspect of genetic discoveries, including forensic genetics. The Miseq® FGx Forensic Genetic System (Verogen) is one of the pioneering forensic NGS that provided a complete system from library preparation to data analysis. The system has been validated by several studies and led to a more practical aspect. Short tandem repeat (STR) is a well-established marker that was designed specifically for human individualization. Since NGS provides different data from fragment analysis, a new STR nomenclature is established to make NGS backward compatible with the previous data. In this study, Thai population were used to evaluate the Miseq® FGx Forensic genetic system (Verogen) in practical aspect, including concordance study and forensic population parameters. In summary, we purposed a practical guideline for sequence-based STRs.

Abstract
This review paper covers the forensic-relevant literature in biological sciences from 2019 to 2022 as a part of the 20th INTERPOL International Forensic Science Managers Symposium. Topics reviewed include rapid DNA testing, using law enforcement DNA databases plus investigative genetic genealogy DNA databases along with privacy/ethical issues, forensic biology and body fluid identification, DNA extraction and typing methods, mixture interpretation involving probabilistic genotyping software (PGS), DNA transfer and activity-level evaluations, next-generation sequencing (NGS), DNA phenotyping, lineage markers (Y-chromosome, mitochondrial DNA, X-chromosome), new markers and approaches (microhaplotypes, proteomics, and microbial DNA), kinship analysis and human identification with disaster victim identification (DVI), and non-human DNA testing including wildlife forensics. Available books and review articles are summarized as well as 70 guidance documents to assist in quality control that were published in the past three years by various groups within the United States and around the world.
