title: What does next-generation sequencing mean for prenatal diagnosis?
abstract: The ability to gain genetic information from the fetus in the mother's blood during pregnancy has been a long desired goal of research in prenatal medicine. The detection of fetal DNA in maternal blood, coupled with the development of the powerful techniques of next-generation sequencing finally transferred this analysis into clinical practice. Following the commercial introduction of noninvasive prenatal testing for aneuploidies, there has been a very strong demand, which has fostered an extreme rapid development and improvement of technology. Publications in this field are so numerous so that it is challenging to keep up with the latest state of the art. Here, we describe the current basic concepts of cell-free DNA-based noninvasive prenatal testing, give an overview of the currently commercially available tests and the chromosomal aberrations that can be identified. We also present current and future concepts for the implementation of cell-free DNA testing into clinical care.
