Although our knowledge of genetic abnormalities that cause health disorders is expanding, the pace of discovering cures for genetic diseases is not nearly as fast. However, technologies applicable to preventing heritable genetic diseases have been developing, among them so-called “next-generation sequencing.” This efficient and inexpensive means to sequence DNA has revolutionized the study of genomics and could play a major role in future preimplantation genetic screening approaches. It may even improve screening during early pregnancy.
