Whole fetal genome sequenced for the first time

BioNews - Whole fetal genome sequenced for the first time: Researchers have sequenced the entire genome of an 18 and a half-week-old fetus using DNA samples from the blood of its mother and saliva samples from its father. These findings provide a proof of principle that a fetus can be examined for genetic conditions using non-invasive technologies. This study, published in Science Translational Medicine, shows that it is possible to non-invasively sequence the whole genome of a fetus and to use that to check for smaller changes in the DNA, including more than 3000 single gene disorders. Currently, non-invasive screening is used to detect conditions where there is an extra copy of a chromosome, known as trisomy - including Down's syndrome, where there are three copies of chromosome 21.
