First live birth in Greece after blastocyst trophectoderm biopsy and preimplantation genetic testing for hereditary angioedema

Abstract

Preimplantation genetic testing for monogenic/single-gene defects (PGT-M) is a well established tool in assisted reproduction. A couple, where the male was carrier of the c.550G>A (p.Gly184Arg) mutation of the SERPING 1 gene causing hereditary angioedema (HAE) attended our clinic for PGT-M. Employing a strategy of preserving embryos after blastocyst trophectoderm biopsy by vitrification cryopreservation, we managed to screen 10 embryos collected from a single IVF cycle. Three embryos were found unaffected after preimplantation genetic analysis for the paternal mutation. The transfer of one normal blastocyst post-thaw resulted in a healthy and uneventful pregnancy and in the live birth of a male neonate on the 38th week of pregnancy. This is the first report of a live birth in Greece after blastocyst trophectoderm biopsy and preimplantation genetic analysis for hereditary angioedema.
