How can balanced chromosome translocation produce healthy babies? For patients with balanced chromosome translocations, it takes luck to have a healthy baby by natural pregnancy. At this time, it is often
You can't afford to gamble, so you need a way to completely avoid inheritance!
For carriers of balanced chromosomal translocation, there is still the possibility of natural childbirth. However, compared with ordinary families, the risks of biochemical pregnancy, fetal arrest, abortion and birth defects are much higher. If
If you are a carrier of translocation and have naturally given birth to a healthy child, you are undoubtedly very lucky. However, we still need to put "preventing women from experiencing multiple pregnancy failures" a top priority, and
Take a risk.
The embryo is usually cultured until the fifth day to form a blastocyst, and one cell is extracted from some cells for testing. Subsequently, these sampled cells will be sent for inspection, and chromosome extraction and analysis will be used to
Determine whether the embryo has a genetic disease and at the same time identify the sex of the embryo. Generally speaking, test results take 2 - 4 weeks. At the same time, all blastocysts will be cryopreserved, waiting for chromosomes
Implant after the results are available. For embryos without abnormalities, implantation can be carried out directly, while for embryos with abnormalities, further PGD examination is required.
Biopsy samples the trophectoderm cells of the blastocyst, and DNA from the cells was extracted for chip testing. After the chip test results are presented, select normal embryos and transfer them into the uterine cavity. PGD is enough
Eliminate pregnancies in children with X-linked recessive genetic diseases, chromosomal diseases and genetic diseases during the pre-pregnancy stage, and avoid the physical and mental pain caused by termination of abnormal pregnancies due to induced abortion.
