Discussion: Genetic Testing

Discussion Topic
Several years ago, a small number of companies in the United States began selling DNA testing kits directly to consumers (referred to as DTC) via the Internet. This market was made possible, in part, by the decreasing costs of genome analysis. DTC testing generally does not produce a full genome sequence, like the Human Genome Project; rather, companies often look at sites in the genome that commonly differ between individuals, known as single nucleotide polymorphisms (SNPs). Companies offer a broad array of tests that report on a person’s ancestry and health, as well as a number of other traits. Whether people should be able to access their genetic information directly from a company is at the center of an on-going debate amongst doctors, patients, ethicists, politicians and regulatory bodies, such as the United States Food and Drug Administration (FDA).
