Revealing Joseon period People's single nucleotide polymorphism associated with lactase gene by ancient DNA analysis of human remains from archaeological sites in Korea. Anat Cell Biol 2023; 56:54-60.

Abstract
Lactase non-persistence (LNP), one of the causes of lactose intolerance, is related to lactase gene associated single nucleotide polymorphisms (SNPs). Since the frequency of LNP varies by ethnic group and country, the research to reveal the presence or absence of LNP for specific people has been conducted worldwide. However, in East Asia, the study of lactase gene associated SNPs have not been sufficiently examined so far using ancient human specimens from archaeological sites. In our study of Joseon period human remains (n=14), we successfully revealed genetic information of lactase gene associated SNPs (rs1679771596, rs41525747, rs4988236, rs4988235, rs41380347, rs869051967, rs145946881 and rs182549), further confirming that as for eight SNPs, the pre-modern Korean people had a lactase non-persistent genotype. Our report contributes to the establishment of LNP associated SNP analysis technique that can be useful in forthcoming studies on human bones and mummy samples from East Asian archaeological sites.

Abstract
From a technical perspective, specimen identity determination in surgical pathology over the last several decades has primarily focused on analysis of repetitive DNA sequences, specifically microsatellite repeats. However, a number of techniques have recently been developed that have similar, if not greater, utility in surgical pathology, most notably analysis of single nucleotide polymorphism (SNPs) and gene panels by next generation sequencing (NGS). For cases with an extremely limited sample or a degraded sample, sequence analysis of mitochondrial DNA continues to be the method of choice. From a diagnostic perspective, interest in identity determination in surgical pathology is usually centered on resolving issues of specimen provenance due to specimen labeling/accessioning deficiencies and possible contamination, but is also frequently performed in cases for which the patient's clinical course following definitive therapy is remarkably atypical, in cases of an unexpected diagnosis, and by patient request for "peace of mind". However, the methods used for identity determination have a much broader range of applications in surgical pathology beyond tissue provenance analysis. The methods can be used to provide ancillary information for cases in which the histomorphology is not definitively diagnostic, as for example for tumors that have a virtually identical microscopic appearance but for which the differential diagnosis includes synchronous/metachronous tumors versus a metastasis, and for the diagnosis of hydropic early gestations versus hydatidiform molar pregnancies. The methods also have utility in several other clinical settings, for example to rule out a donor-transmitted malignancy in a transplant recipient, to monitor bone marrow transplant engraftment, and to evaluate natural chimerism.

Abstract
The non-coding displacement (D) loop of the human mitochondrial (mt) genome contains two hypervariable regions known as HVR1 and HVR2 that are most often analyzed by forensic DNA laboratories. The massively parallel sequencing (MPS) protocol from Illumina (Human mtDNA D-Loop Hypervariable Region protocol) utilizes four sets of established PCR primer pairs for the initial amplification (enrichment) step that span the hypervariable regions. Transposase adapted (TA) sequences are attached to the 5'-end of each primer, allowing for effective library preparation prior to analysis on the MiSeq, and AmpliTaq Gold DNA polymerase is the enzyme recommended for amplification. The amplification conditions were modified by replacing AmpliTaq Gold with TaKaRa Ex Taq® HS, along with an enhanced PCR buffer system. The resulting method was compared to the recommended protocol and to a conventional non-MPS approach used in an operating forensic DNA laboratory. The modified amplification conditions gave equivalent or improved results, including when amplifying low amounts of DNA template from hair shafts which are a routine evidence type in forensic mtDNA cases. Amplification products were successfully sequenced using an MPS approach, addressing sensitivity of library preparation, evaluation of precision and accuracy through repeatability and reproducibility, and mixture studies. These findings provide forensic laboratories with a robust and improved enrichment method as they begin to implement the D-loop protocol from Illumina. Given that Ex Taq® HS is a proofreading enzyme, using this approach should allow for improved analysis of low-level mtDNA heteroplasmy.
