The genetic polymorphism of two salivary enzymes (esterase and alpha-amylase) was studied in individuals from eight districts of Greece. The pooled gene frequencies were: SetS = 0.63, SetF = 0.37, AMY1 = 0.87, AMY2 = 0.10, AMY3 = 0.02, and AMY4 = 0.01. There was no intrapopulation heterogeneity, while there was a significant difference between the Greeks and the few other European populations studied.

Background: Adverse childhood events (ACEs) have been associated with an increased risk of psychiatric disorders in young adulthood. To identify at-risk individuals and potential strategies to combat the negative impacts of ACE, this study investigated the mediating role of exercise in the relationship between psychological distress and ACEs. Further, we examined the moderating effect of the BDNF polymorphism in the mediation relationship.

Salivary and pancreatic amylase are encoded by AMY1 and AMY2, respectively, which are located within a single genomic locus that has undergone substantial structural variation, resulting in varying gene copy numbers across species. Using optical genome mapping and long-read sequencing, Yilmaz, Karageorgiou, Kim, et al. achieved nucleotide-level resolution of this locus across different human populations, offering new insights into how copy number variation contributes to human adaptation.

Aim: The study was designed to evaluate molecular alterations, relevant to the prognosis and personalized therapy of salivary gland cancers (SGCs).
Materials And Methods: DNA was extracted from archival tissue of 40 patients with various SGCs subtypes. A targeted next-generation sequencing (NGS) panel was used for the identification of small-scale mutations, focal and chromosomal arm-level copy number changes.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.
