Abstract
Advances in genetic testing field have contributed to the boom in carrier screening technology. Expanded carrier screening can effectively identify more high-risk couples than traditional guideline-based carrier screening. The introduction of extended carrier screening has increased the number of referrals for preimplantation genetic testing (PGT) for monogenic disease and enriched the types of disease diagnosed. Expanded carrier screening combined with PGT technology is changing the clinical strategy of genetic risk assessment and preventing birth defects by accurately identifying reproductive risk information and rationalizing fertility planning.
