Abstract

Noninvasive prenatal DNA testing is the vanguard of genomic medicine. In only four years, this screening test has revolutionized prenatal care globally and opened up new prospects for personalized medicine for the fetus. There are widespread implications for increasing the scope of human genetic variation that can be detected before birth, and for discovering more about maternofetal and placental biology. These include an urgent need to develop pretest education for all pregnant women and consistent post-test management recommendations for those with discordant test results. The reduction in invasive testing has had downstream effects on specialist training and caused many countries to re-examine their national approaches to prenatal screening. Finally, the accumulating datasets of genomic information on pregnant women and their fetuses raise ethical issues regarding consent for future data mining and intellectual property.
