Preimplantation Genetic Diagnosis (PGD) for chromosome rearrangements
• Chromosome rearrangements include Robertsonian and reciprocal translocations (the most common form of chromosome abnormality in humans, present in approximately 1 in 500 individuals), periand paracentric inversions, interand intra-chromosomal insertions, deletions, duplications, and complex chromosome rearrangements (CCRs). • In all cases presenting for PGD, the risk of viable abnormality sho...
متن کاملPreimplantation genetic diagnosis of chromosome balance in embryos from a patient with a balanced reciprocal translocation.
Duplications or deletions are present in a high percentage of the gametes produced by individuals carrying balanced translocations. Preimplantation genetic diagnosis was used to examine chromosome balance in embryos from a patient having a reciprocal translocation within the short arms of chromosomes 5 and 8 (46,XX,t(5;8)(p13;p23)). This woman has two sisters with the translocation unbalanced, ...
متن کاملPreimplantation genetic diagnosis of numerical and structural chromosome abnormalities.
The causes of the decline in implantation rates observed with increasing maternal age are still a matter for debate. Data from oocyte donation strongly suggest that in women of advanced reproductive age, the ability to become pregnant is largely unaffected while oocyte quality is compromised. The incidence of chromosomal abnormalities in embryos is considerably higher than that reported in spon...
