Until recently, classical sequencing methods were used to investigate the cause of miscarriages. They only allowed the analysis of short DNA fragments - and were therefore less precise. Next-generation sequencing (NGS), or next-generation sequencing (NGS), brings a new, higher quality to genetic research. From now on, specialists can study entire human genomes, not just selected parts. What exactly is NGS and why has it been used to study the causes of miscarriages?
