Why Is Metagenomics Critical to the Future of Modern Medicine? Metagenomics as most of you know is a subject that studies genetic content of samples collected from the environment. Broadly, the subject is referred to as eco genomics, environmental genomics, community genomics etc. There is a decent overlap between microbiology and metagenomics, it has been found out that a vast majority of the subject which is microbial diversity has been left out from the scope of study owing to its limitation. Metagenomics is a much more sophisticated technique that has proven to circumvent drawbacks of translational studies by offering scientists ability to study microscopic life from closer quarters than before and all of its hidden diversity. This is going to be invaluable to understanding of disease causing microbes and formulating cures for maladies that do not responding to the available treatments. Metagenomic analysis helps to establish host-pathogen interaction with focus of pathogenicity. On a side note, exome sequencing is fast becoming mainstream diagnosis for a number of common and rare genetic disorders. If you believe in being proactive when it comes to your health, then get a whole genome sequencing or SNP genotyping done to avert risks of falling prey to hereditary conditions in the future. Check with a genome sequencing lab to find out about the exome sequencing cost.
