Researchers at Johns Hopkins University School of Medicine in the US have developed a new technique to help couples that are affected by or carry a genetic disease have IVF babies free of the condition and other chromosomal abnormalities.

The modified multiple displacement technique allows physicians to amplify carbon copies of the DNA obtained from an embryo, which in turns allows for multiple genetic tests to be performed.

In the past, researchers have been limited by the small size of embryos, and have only been able to test IVF embryos for a specific gene mutation that is known to exist in either parent, or other types of chromosomal abnormalities such .

Paul Brazina, a clinical fellow in obstetrics and gynecology at John Hopkins, said, “We were able to amplify the genomic DNA accurately to the point where both single-gene testing and aneuploidy screening could be done. Up till now it has only been one or the other.”
