What is IVF PGD?
IVF PGD is in vitro fertilization pre-implantation genetic diagnosis. It analyzes expendable cells from days-old embryos that have been fertilized in vitro, allowing parents undergoing IVF to determine which, if any, embryos are affected by ALD and choose healthy embryos for implantation. This is only possible for families in which a mutation in the ALD gene has already been identified.
