ABSTRACT
In 2001, the first draft sequence of the human genome was released, the culmination of a decade-long, multibillion-dollar effort. Since then, an OMICs platform has been proposed to further evaluate and edit the human genome for diagnostic and therapeutic purposes. The Human Genome Project opened a Pandora's box, expanding the forensic laboratory physicians' toolbox. Kinship analysis has been used extensively for parentage testing and identifying cases of human remains and missing persons. The Combined DNA Index System has played a significant role in forensic DNA databases. Nanopore sequencing and improved genomic tools aid enormously in identifying amplicons from degraded samples. The application of genomics in determining the potential channelopathies of sudden cardiac death (SCD) has been an enormous step forward in recent years in forensic histopathology. We reviewed the literature. Kong et al.'s meta-analysis of the mean allele frequencies of SCN5A, NOS1AP, KCNH2, KCNE1, and KCNQ1 genes across Black, Caucasian, Asian, and Hispanic ethnicities has been pivotal to forensic science in the last decade. The authors used sequenced genomic data from the Exome Aggregation Consortium to compare allele frequencies between different ethnicities. They found that Asians had the highest overall mean allele frequencies for NOS1AP and SCN5A, Caucasians had the highest KCNH2 frequency, and Hispanics had the highest KCNQ1 frequency. In 2026, the call for increased professionalism in clinico-molecular autopsy and forensic laboratory sciences is driven by rapid technological advancements (e.g., forensic molecular genomic autopsies), critical workforce shortages in some geographical areas, and the increasing complexity of death investigations. This professionalization focuses on standardizing molecular protocols, enhancing ethical frameworks, and addressing the need for specialized interdisciplinary expertise.
