Pre-implantation Genetic Testing for Monogenic Diseases (PGT-M) is a medical technology used in IVF programs to identify the presence of certain genetic disorders in embryos before they are transferred to the patient’s uterus. This technology is performed on couples who have a family history or a high genetic risk of passing on certain genetic disorders to their children.
PGT-M is performed by taking a few cells from the trophoblast (the future placenta) that is developed in the laboratory and performing genetic analysis to evaluate whether the embryo has a genetic disorder that is inherited from one or both parents. If the embryo is determined not to have a genetic disorder, then it will be transferred to the patient’s uterus. This technology allows couples to have healthy babies that do not inherit genetic disorders that are suffered by their parents, such as Thalassemia, Spinal Muscular Atrophy, Cystic Fibrosis, and Hemophilia.
