CRISPR

58.1K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Area of Science:

  • Reproductive genetics
  • Assisted reproductive technology (ART)

Background:

  • Preimplantation genetic testing (PGT) is increasingly used in ART, with expanded indications.
  • Over one-third of US ART centers employ PGT for various genetic and non-genetic conditions.

Purpose of the Study:

  • Critically review PGT developments, highlighting limitations.
  • Identify future research and practice directions in PGT.

Main Methods:

  • Review of current PGT technologies and their applications.
  • Analysis of limitations in existing PGT protocols.

Main Results:

  • Higher resolution PGT reveals genetic variations of unclear significance.
  • Euploid embryo transfer success rates require improvement, indicating a need for better embryo selection.

Conclusions:

  • Further research is essential to unify PGT for diverse conditions into a single test.
  • Development of non-invasive PGT is crucial to mitigate risks associated with embryo biopsy.
