Introduction
By collecting samples of miscarriage tissue, blood from adults and children, and conducting next-generation high-throughput sequencing, and through bioinformatics comparative analysis, we can accurately analyze chromosomal aneuploidy variations and chromosomal deletions/duplications above 0.1M in the sample. By analyzing the chromosomal abnormalities in the miscarriage tissue, combined with the genetic background of both spouses, we can assist in analyzing the genetic factors that cause miscarriage and provide scientific basis for subsequent diagnosis and treatment.
