One step test finds genetic and chromosomal abnormalities in embryos A one-step embryo test for both genetic and chromosomal abnormalities has been developed by researchers based in the USA and the UK. The technique, known as genome-wide karyomapping, was capable of not only detecting diseases caused by a specific gene mutation, in this case cystic fibrosis, but that it was also capable of detecting aneuploidy (an abnormal number of any of the 23 pairs of chromosome) at the same time. Clinical trials for couples seeking fertility treatment will begin later this year.
