Preimplantation Genetic Testing for Monogenic Disorders (PGT-M)
NxGen Preimplantation Genetic Testing for Monogenic Disorders (PGT-M) can determine whether any specific genetic conditions you tested positive for are present in your IVF embryos. This will allow your IVF doctor to select only those unaffected by the disorder for transfer, drastically reducing the risk of having an affected child. This service is a follow-up screen for couples or individuals who have had NxGen carrier screening as recommended for them by their physician.
What Is It?
After in vitro fertilization, a couple can effectively screen any resulting embryos for a single gene condition using PGT-M (preimplantation genetic testing for monogenic disorders). PGT-M is used to screen for genetic conditions such as cystic fibrosis, sickle cell anemia, Tay-Sachs disease, Fragile X syndrome, and spinal muscular atrophy (SMA). Since the Super Panel screens for these conditions, only couples who screen positive for the same genetic condition need to undergo PGT-M screening.
Who Should Take It?
• Couples whose carrier screening identify them as carriers of a genetic disease or disorder
By opting to use NxGen's PGT-M program, we can determine whether the specific genetic condition(s) a patient tested positive for are present in the IVF embryos. This will allow the IVF doctor to select only those unaffected by the disorder for the transfer, drastically reducing the risk of having an affected child. NxGen PGT-M can screen for over 120 genetic conditions and offers best-in-class accuracy.
