How many genetic disorders can be tested with Preimplantation Genetic Diagnosis – PGD?
PGD is used to test for single gene disorders like Cystic Fibrosis, chromosomal abnormalities such as Down Syndrome and gender linked disorders like Hemophilia A and certain cancers like Breast Cancer. The number of genetic disorders that can be screened depends on whether a disorder’s corresponding gene marker has been identified. Currently, we can test for about two dozen genetic disease including Huntington’s Disease, Cystic Fibrosis, Tay Sachs Disease, Hemophilia A, Fragile X Syndrome, and Duchenne Muscular Dystrophy. In the near future, female ovum also can be checked for a gene that increases the propensity to develop breast and ovarian cancer.
