Genetic polymorphisms within genes encoding immune checkpoints—particularly programmed cell death protein 1 (PD-1), its ligand PD-L1 and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4)—have ...

Balancing selection is a fundamental evolutionary force that maintains multiple alleles at a locus within a population over extended periods. Unlike directional selection, which drives alleles to ...

Despite global vaccination efforts, COVID-19 continues to pose significant risks, leading to severe complications and fatalities. These risks are driven by disrupted coagulation, impaired fibrinolysis ...

The figure illustrates the major categories of genes that may influence susceptibility to dental caries, organized by their biological functions and pathways. These groups include: (1) Enamel ...

In a recent study published in the journal Nutrients, researchers in Canada reviewed the genetic mechanisms contributing to individual variation in vitamin D (VD) levels in circulation. Humans can ...

Genes make us who we are—but are they shaped by chance, natural selection, or something else?
