PGD Preimplantation Genetic Diagnosis
PGT provides information about the genetic of an embryo prior to implantation. It can test for chromosomal abnormalities,and genetic diseases. Biopsy is performed at day 3 by removing 1 embryo cell, and at day 5 by removing 4-6 embryo cells to be analysed.
The goals of testing are; improvement of the chances of pregnancy within lowering the risk of miscarriage,and having a healthy baby. PGT can also be used to detect possible genetic disorders of embryos prior to fertilizaiton in IVF.
PGT is essential for the parents who have inherited disorders, who take IVF practices or micro injections because it provides healthy babies.
FISH (Fluorescence in situ Hybridization) technique is used to screen eggs for chromosomal problems prior to fertilization. aCGH (array Comparative Genomic Hybridization) and NGS (Next Generation Sequencing) can be used to screen 24 chromosome. Molecular genetic techniques are used to detect genetic disorders like; Thalassemia, cystic fibrosis, spinal muscular atrophy (SMA). Human lekocyte antigen (HLA) and Rh genotype can be defined.
PGT is also used for gender selection. There are 2 reasons for gender selection:
1. Family balancing
2. Preventing gender linked genetic diseases
Preimplantation Genetic Diagnosis
When genetic parents have a known genetic abnormality or have a sick child, testing is performed on an embryo to determine if it also carries a genetic abnormality.
PGD avoids a high risk of having a baby affected with a genetic disease prior to implantation. It is offered in case of repeated miscarriage. PGD aids elder women, and couples who failed in their IVF attemps many times. It ensures healthy babies.
