Cytogenomics is a branch of genetics that combines cytogenetics and genomics to study the structure, function, and evolution of genomes, especially in the context of human disease and development. It involves the analysis of the chromosomal and genome-wide changes that occur during the genotypic response to environmental or internal cellular and molecular mechanisms, including epigenetic, metabolic, and signal transduction pathways.

The main objective of cytogenomics is to identify specific chromosomal or genomic alterations that are associated with certain diseases or disorders, and to understand the underlying mechanisms of action. This is typically achieved by using high-throughput sequencing technologies, such as array comparative genomic hybridization (aCGH) and microarray-based techniques, to analyze DNA copy number variations, deletions, duplications, and mutations at a high resolution.

Cytogenomics has a wide range of applications, including the diagnosis and prognosis of cancers, genetic disorders, and neurodevelopmental and psychiatric disorders. It also contributes to the development of new genomic-based diagnostic tools, personalized medicine approaches, and targeted therapies. Moreover, cytogenomics enables the study of genetic variations in different populations, promoting the understanding of human genetic diversity and its implications for health and disease.

In recent years, the field of cytogenomics has rapidly advanced, driven by significant improvements in next-generation sequencing technologies and computational methods for data analysis. These advances have greatly expanded our knowledge of the relationship between genome structure and function, and have paved the way for the development of novel treatments and therapies based on precise understanding of genetic and epigenetic mechanisms.
