The “mosaic” embryo: misconceptions and misinterpretations in preimplantation genetic testing for aneuploidy

VOLUME 116, ISSUE 5, P1205-1211

Abstract:

Preimplantation genetic testing for aneuploidy (PGT-A) remains one of the most controversial topics in reproductive medicine. With more than 40% of in vitro fertilization cycles in the United States reportedly involving PGT, both those in favor of and those opposed to PGT-A have significant interest in the efficacy of PGT-A. Ongoing issues include what patient population, if any, benefits from PGT-A, the true frequency of chromosomal mosaicism, whether embryonic aneuploidies self-correct, and how practitioners manage embryos designated as “mosaic.” This review addresses several misconceptions and misinterpretations of data surrounding the genetic analysis and prediction of mosaicism in the preimplantation embryo.

About your Figure 3. It's a very interesting information. We potentially miss informations due to this noise.

We can modify the noise level by using different filters on NGS platform, isn't it ?

Thanks
