High Quality Content by WIKIPEDIA articles! Preimplantation Genetic Haplotyping (PGH) is a clinical method of preimplantation genetic diagnosis (PGD). PGH was first developed in 2006 at London's Guy's Hospital and greatly advances PGD by using DNA fingerprinting rather than identifying the actual genetic signature (such as point mutations). n medicine and (clinical) genetics preimplantation genetic diagnosis (PGD or PIGD) (also known as embryo screening) refers to procedures that are performed on embryos prior to implantation, sometimes even on oocytes prior to fertilization. PGD is considered another way to prenatal diagnosis. Its main advantage is that it avoids selective pregnancy termination as the method makes it highly likely that the baby will be free of the disease under consideration. PGD thus is an adjunct to assisted reproductive technology, and requires in vitro fertilization (IVF) to obtain oocytes or embryos for evaluation.
