Growth in this segment can be attributed to the increasing maternal age, rising incidence of aneuploidy disorders, and strategic initiatives by key players to provide technologically advanced PGS products for aneuploidy screening.
Autosomal aneuploidy (especially trisomy 21, 18, and 13) screening is the most common and cost-effective prenatal screening test.
Two such approaches currently in practice include targeted enrichment of sequences derived from regions of interest, typically sex chromosomes and chromosomes prone to aneuploidy (19-21), and selective amplification of polymorphic loci on the chromosomes of interest (22-25).
The majority of patients elected to have NIPT based on positive screening on CFTS, or markers of aneuploidy detected on the second-trimester ultrasound scan (Table 2).
The advantage of doing these analyses simultaneously is that researchers can now see how aneuploidy is affected by structural variations and vice versa.
The technology which is used in cell-free DNA analysis and its application to prenatal screening for aneuploidy is rapidly changing.

In addition, the American Congress of Obstetricians and Gynecologists (ACOG) and the Society of Maternal Fetal Medicine (SMFM) reportedly recognize the tremendous potential of cell-free DNA (cfDNA) testing, concluding that cfDNA testing can be offered to patients at increased risk of aneuploidy.
This edition has new sections on direct and indirect testing for mutations as a universal approach to tracing their inheritance and de novo mutations, expanded indications emphasizing the practical observation of preimplantation genetic diagnosis for various cancers and inherited cardiac diseases, and HLA typing combined with 24-chromosome aneuploidy testing, as well as updates to current technologies and information on their accuracy, reliability, and safety.
