Abstract
Preimplantation genetic diagnosis (PGD) has experienced a considerable technical evolution
since its first application in the early 1990s. The technology for single-cell genetic
analysis has reached an extremely high level of accuracy and enabled the possibility
of performing multiple diagnoses from one cell. Diagnosis of a monogenic disease can
now be combined with aneuploidy screening, human leukocyte antigen typing, and DNA
fingerprinting. New technologies such as microarrays are opening the way for an increasing
number of serious genetic defects to be detected in preimplantation embryos. The new
PGD techniques will empower patients and clinicians to screen for almost any kind
of genetic problem in embryos, with the potential to change completely the manner
in which parents approach and manage genetic disease.
