Preimplantation Genetic Diagnosis
Preimplantation genetic diagnosis (PGD) is used to test the genetic makeup of embryos to prevent the transmission of inherited diseases with detrimental effects such as cystic fibrosis, spinal muscular atrophy and beta – thalassaemia [1] [2]. It was first used in the United Kingdom in the 1980s of arenoleucodystrophy and primarily focusing on sex- linked disorders [2][3]. PGD is now capable of detecting single cell defects (molecular) and chromosomal disorders resulting from the inversion, translocation or deletion of chromosomes (cytogenic) [1],[4]. PGD can be applied to the embryo at different stages. That is on polar bodies, blastomeres or blastocyst [1].
Depending on the type of genetic disorder, PGD utilises different methods of genetic testing. These include Fluorescence in situ hybridisation (FISH) which is used for sex – linked disorders and detects chromosomal rearrangements [4][5] and Embryo halotyping which allows the identification of chromosomes causing the inherited disorder through knowledge of the pattern of closely linked markers [1]. Polymerase chain reaction (PCR) is also widely used to detect molecular abnormalities [4].
