Early diagnostics of genetic diseases and defects PGD-NGS (PGT-M)
Preimplantation Genetic Testing for Monogenic/Single Gene Defects (PGD, PGT-M) is a form of genetic testing that allows the couples with an increased risk of single gene defects to examine the embryos before their transfer to the uterus. PGD (PGT-M) is performed in conjunction with IVF.
PGD (PGT-M) can be performed for any known, inherited, single gene, including autosomal recessive genes (e.g. cystic fibrosis), autosomal dominant genes (e.g. Huntington’s disease), or other genetic disorders.
PGD (PGT-M) comprises molecular tests of the blastomeres collected from the embryo, and helps to identify the embryos without genetic defects for the intrauterine transfer.
The complete PGD (PGT-M) procedure involves a few stages:
- analysis of the clinical status
- development of a proper genetic test
- in-vitro fertilization,
- embryonic biopsy
- genetic diagnostics (PGT-M)
- embryotransfer
