Description
Inclusion Criteria:
Blastomeres biopsied from spare embryos ((A) Embryos diagnosed as genetically abnormal using current PCR- and FISH-protocols; (B) Embryos diagnosed as normal for the investigated region using current PCR- and FISH-protocols, but not of sufficient quality to be transferred or frozen; (C) Embryos of the sex that is selected against following PGD based sex-selection, or embryos of the sex that is selected for but of insufficient quality to be transferred or frozen; (D) Embryos that were not biopsied in a PGD cycle since they suffer a slight growth delay.) derived from following patient groups:
- The first patient group involve couples suffering a complex chromosomal rearrangement (CCR), which is defined as a structural chromosomal rearrangement with at least three breakpoints and an exchange of genetic material between two or more chromosomes.
- The second patient group involve couples with X-linked recessive disorders.
- The third patient group consists of couples that carry a balanced chromosomal rearrangement - a translocation, insertion or inversion - that may result in recurrent miscarriage or aneuploid, severely handicapped offspring.
- A fourth patient group are couples at risk for the transmission of monogenic diseases.

PGD-FISH
Following couples opting for preimplantation genetic diagnosis on the basis of FISH:
|
We aim to collect single blastomeres from spare IVF embryos of 30 couples to optimize and test methods for single cell haplotyping.
We aim to collect 20 and 10 couples coming to the fertility centre for FISH- or PCR-based PGD respectively.
In both groups, at least 5 different indications for PGD will be collected.
Per couple, we will perform 10 SNP-arrays: 2 for the couple donating the embryo, 4 for family members (often parents of the couple) and 4 for blastomeres since we aim to pick 2 cells from 2 embryos per couple.
For five couples, 2 blastomeres of all available embryos will be aspirated to validate and optimize the phasing methods.
Finally, for some embryos, all blastomeres will be picked to be able to prove the reproducibility of single cell haplotyping.
