Early diagnosis: genetic diseases can be detected as early as 5 weeks of gestation24.05.2022
Non-invasive diagnosis of chromosomal diseases of the fetus is carried out by the blood of the expectant mother. In our country, doctors conduct it from the 10th week of pregnancy. Their American colleagues went further: an experimental test made it possible to identify genetic defects for a period of 5 weeks.
A breakthrough in this type of diagnostics belongs to scientists from the University of Wayne . During research, they were able to isolate cells from the cervix of expectant mothers that form the placenta and provide information about the DNA of the fetus. For the purity of the experiment, the doctors compared these samples with data obtained by research at a later stage of pregnancy . The result showed a perfect fit.
The results of the successful experiment were published in Science Translational Medicine. The authors of the study emphasized that the non-invasive diagnostics they studied provides “the ability to conduct a genetic test 5-10 weeks earlier than existing testing methods.”
Experts from Wayne University intend to go further in their research. Dr. Randall Armant noted: “This will give parents information about whether their child will have genetic disorders later.”
