He said: "This work opens up the possibility that we will be able to scan the whole genome of the fetus for more than 3,000 single-gene disorders through a single, non-invasive test." Prenatal testing is already popular for Down Syndrome and several other genetic disorders, but it's not without risk at all. An amniocentesis carries the threat of premature birth or miscarriage. Where a genetic disorder is located, most parents opt to abort the fetus because ultimately, the possibility of not giving birth to a child with a genetic disorder is the main reason for carrying such tests out in the first place.
Hence, scientists though excited about the potential these findings hold also warn that fetal genome mapping could raise serious ethical questions and that these prenatal tests will be used in a way that society deems acceptable in the future. At the moment, work is ongoing to improve the accuracy of the technique, and to develop the possibility of screening for genetic tests that are currently untestable. Scientists found some false positives as well, so apparently there is quite a lot of work ahead. What is your opinion about this new discovery?
