Preconception Genetic Testing
We recommend that couples take a consultation with a clinical genetic before trying to conceive through IVF. This consultation is especially important for couples with a family history of genetic diseases, which threatens to reappear in the following generation. Genetic testing can also uncover whether one of the partners is a carrier – if they have a predisposition to a hereditary disease which did not yet appear in the family, but could in the children of the prospective parent.
How PGT Is Done:
- Genetic testing begins with a medical consultation. A clinical genetic discusses the family and personal anamnesis of hereditary diseases in both partners.
- Then, a blood sample is taken in order to examine your chromosomes and compose your karyotype (state of all chromosomes in cell nucleus)
- Concerning women, we also examine predispositions to heightened blood clotting – thrombophilic mutations (Leiden mutation in gene for factor V and prothrombin mutation in gene for factor II).
- In men with a pathological spermiogramme finding, we focus on discovering specific mutation on the level of genes (CFTR gene mutation) and parts of chromosomes (microdeletions of Y chromosome).
- Based on our findings, we recommend the most suited treatment and in some cases of IVF, an additional genetic testing of embryo before transferring it to uterus (PGT).
