Genomics is an interdisciplinary field of biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes.In contrast to genetics, which refers to the study of individual genes and their roles in inheritance, genomics aims at the collective characterization and quantification of all of an organism.

Variants in genetic codes are responsible for Huntington's disease, Lou Gehrig's disease (ALS), schizophrenia, diabetes and attention-deficit disorder, as previous research has shown. While other tools, based on algorithms, have been developed to detect genetic variants, they provide incomplete information, especially for the VNTRs A variant is a new strain of the SARS-CoV-2 virus, the virus that causes COVID-19. Variants occur through mutations, which are changes in the genetic code of a virus. Variants have specific gene mutations that make them unique and different from the original SARS-CoV-2 virus. Viruses, including SARS-CoV-2, naturally change or mutate over time.

Genome Variation - an overview ScienceDirect Topic

Genomic surveillance of SARS-CoV-2 variants has largely focused on mutations in the spike glycoprotein, which mediates attachment to cells and is a major target of neutralizing antibodies. There is intense interest in whether mutations in the spike glycoprotein mediate escape from host antibodies and could potentially compromise vaccine. Genetic testing looks for specific inherited changes (variants) in a person's genes. Genetic variants can have harmful, beneficial, neutral (no effect), or unknown or uncertain effects on the risk of developing diseases. Harmful variants in some genes are known to be associated with an increased risk of developing cancer This site covers HGVS-nomenclature, the recommendations for the description of sequence variants. It is used to report and exchange information of variants found in DNA, RNA and protein sequences and serves as an international standard.
