Mother’s Blood Shows Birth Defects in Fetal DNA
4.7.12, AMY DOCKSER MARCUS
Researchers said Wednesday they were able to sequence the entire genome of a fetus using only a blood sample from the mother, an advance in the effort to find noninvasive ways for expectant parents to determine if their babies will be born with genetic conditions.
The findings, from researchers at Stanford University School of Medicine, reflect intense interest in finding fast, relatively inexpensive and accurate ways to predict genetic conditions without the risks associated with currently available tests. Amniocentesis, for instance, which many couples rely on to obtain some genetic information about the fetus, requires insertion of a needle through …
