If you’re navigating the journey of parenthood, especially with hereditary concerns, Preimplantation Genetic Testing (PGT) can be a game-changer. This innovative technique allows reproductive specialists to screen embryos created through in vitro fertilization (IVF) for specific genetic conditions. Essentially, it helps ensure that only healthy embryos are selected for transfer, significantly lowering the risk of miscarriage and enhancing the chances of a successful pregnancy.
What is PGT?
PGT involves a biopsy where one or two cells are gently taken from an embryo during its blastocyst stage. This process allows for the examination of the embryo’s genetic material for any known genetic disorders before implantation. Couples who are aware of carrying certain genetic mutations often opt for this testing to mitigate risks associated with genetic conditions.
Common Genetic Disorders
- Autosomal Recessive Disorders: If both partners are carriers of a mutation, there’s a 25% chance of having an affected child. Conditions like Cystic Fibrosis and Sickle Cell Anemia fall into this category.
- X-Linked Disorders: These are more common in males since they have only one X chromosome. Disorders such as Hemophilia and Duchenne Muscular Dystrophy are examples.
- Dominant Disorders: Only one copy of the mutated gene from a parent can cause the disease, like Huntington’s Disease or Marfan Syndrome.
- Chromosomal Disorders: These occur when there’s an abnormal number of chromosomes, leading to conditions such as Down Syndrome.
