DNA testing is a proven and effective way to discover potential health problems. But as with other scientific techniques, the details of how it works and its limitations are worth knowing before using it every day. Wrong ways of researching a subject can lead to bizarre and unexpected results.
Genotype research and development (GRADE) is the process of analyzing genotype data to determine the genetic risk for a disease or trait. It can be used to efficiently target new drugs, products, or research studies. Genotype research and development has its own set of challenges that need to be solved before it can be considered a reality.
