[Focus on the development of preimplantation genetic testing in the field of birth defects and rare diseases prevention and control].

ABSTRACT

Birth defects and rare diseases are serious challenges in China and even in the world, and most of them lack effective treatment. Preimplantation genetic testing (PGT) prevents the occurrence of this kind of disease at the source by carrying out genetic testing in the preimplantation stage and selecting normal embryos for transplantation. In this paper, the methods of PGT for birth defects and rare diseases and their latest progress are described.
