Hace 3 días · Recently, the use of polygenic risk scores (PRS) within preimplantation genetic testing (PGT) has been introduced commercially (Treff et al., 2019a). This is referred to as PGT-P or polygenic embryo screening. The aim of PGT-P significantly differs from more established forms of PGT, i.e. PGT-M (testing embryos for monogenic conditions), PGT-SR (testing embryos for chromosomal rearrangements ...
