PID in der Reproduktionsmedizin

Preimplantation genetic diagnosis in assisted reproduction Preimplantation genetic diagnosis (PGD) describes the biopsy of one or more cells of an in vitro fertilized embryo and its genetical analysis before the transfer of the embryo into the uterus. Since the modification of the Embryonenschutzgesetz a PGD can be lawfully performed in Germany. Several diagnostic methods can be performed: FISH for the detection of maternal translocations on polar bodies, at the moment the most applied the array‐CGH for the screening of aneuploidies and the detection of translocations and also in the case of monogenic diseases PCR followed by sequencing. In the near future next generation sequencing will possibly replace all mentioned methods.
