Objectives: Variation in the human genome may explain genetic contributions to complex traits and common diseases.
Findings: Until recently, single nucleotide polymorphisms were thought to be the most prevalent form of interindividual genetic variation. However, structural genomic rearrangements such as deletions, duplications, and inversions lead to variation in gene copy number and contribute even more to genomic diversity. Other sources of genomic variation include noncoding genes, pseudogenes, and mobile genetic elements (transposons).
Conclusions: Genome dynamics, including changes in gene number and position as well as epigenetic modifications of coding and noncoding sequences, can affect regulation of gene expression and may contribute to the variability of complex phenotypes.

The stone marten (Martes foina) is an important species for cytogenetic studies in the order Carnivora. ZooFISH probes created from its chromosomes provided a strong and clean signal in chromosome painting experiments and were valuable for studying the evolution of carnivoran genome architecture. The research revealed that the stone marten chromosome set is similar to the presumed ancestral karyotype of the Carnivora, which added an additional value for the species.

Importance: Sensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.
Objective: To evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.
Design, Setting, And Participants: Data were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium.

The extent of functional sequences within the human genome is a pivotal yet debated topic in biology. Although high-throughput reverse genetic screens have made strides in exploring this, they often limit their scope to known genomic elements and may introduce non-specific effects. This underscores the urgent need for novel functional genomics tools that enable a deeper, unbiased understanding of genome functionality.
