The Human Genome Project
In short, it enabled powerful form of preventive, personalized and preemptive medicine.
By tailoring recommendations to each person’s DNA, health care professionals can work with individuals to focus efforts on specific strategies that are most likely to maintain health for that particular individual, and in some cases their family as well.
Hereditary Cancer Assessment. For those of us with a family history of a certain conditions or diseases, getting a DNA assessment before we have symptoms may show if we're at risk of developing that condition. For example, this type of test may be useful for identifying whether or not we and/or our family are at higher risk of hereditary colorectal, prostate, breast, ovarian, pancreatic or other cancers.
Coronary Artery Disease leading to heart attack, stroke, and heart failure can run in families, indicating inherited genetic risk factors inherited from your mother and father. If you know about your risk ahead of time, you may be able to get ahead of the problem, before it causes symptoms or becomes dangerous.
Pharmacogenomics is a DNA assessment that looks at how genetic variation affects our individual response to a medication. This science combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to help doctors select the drugs, combination of drugs, and doses best suited for us as individuals, based on our genetic makeup.
For example, on an individualized basis, pharmacogenomic tests can identify the most effective blood-thinner or anti-depressant and their dosages, or if codeine will in fact metabolize to morphine, which it must do to be an effective pain mitigator.
