Impact of Genomics on the Future of Medicine and Health

Genomics is the study of whole genomes of organisms, and incorporates elements from genetics. Genomics uses a combination of recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyse the structure and function of genomes.

The genomics is defined as the study of a gene and its functioning. The concept of genomics is aimed to understand the architecture of the genome which is comprised of the deoxyribo nucleic acid (DNA), ribo nucleic acid (RNA) and proteins.

Genomics is meant to examine the molecular mechanisms and the interaction of genetic and environmental factors in the diseases. The report would be of an interest to various stakeholders operating in the genomics market. These stakeholders include hospitals, research institutes, medical device suppliers, diagnostic centers, academic institutes, market research, equipment manufacturers, and consulting firms.

Pharmacogenomics is the study of the role of the genome in drug response. Its name (pharmaco- + genomics) reflects its combining of pharmacology and genomics. Pharmacogenomics analyzes how the genetic makeup of an individual affects his/her response to drugs.

It deals with the influence of acquired and inherited genetic variation on drug response in patients by correlating gene expression or single-nucleotide polymorphisms with pharmacokinetics (drug absorption, distribution, metabolism, and elimination) and pharmacodynamics (effects mediated through a drug's biological targets).

The term pharmacogenomics is often used interchangeably with pharmacogenetics. Although both terms relate to drug response based on genetic influences, pharmacogenetics focuses on single drug-gene interactions, while pharmacogenomics encompasses a more genome-wide association approach, incorporating genomics and epigenetics while dealing with the effects of multiple genes on drug response
