Polar body-based preimplantation genetic diagnosis for Mendelian disorders.
Introduced >20 years ago, the use of polar bodies (PBs), involving sequential removal and genetic analysis of the first (PB1) and second (PB2) PB, provides the option for pre-embryonic diagnosis, when the objection to the embryo biopsy procedures makes preimplantation genetic diagnosis (PGD) non-applicable. PB-based approach has presently been utilized in PGD for genetic and chromosomal disorde...
متن کاملPreimplantation genetic diagnosis of X-linked retinoschisis.
The aim of this study was to perform preimplantation genetic diagnosis (PGD) for X-linked retinoschisis using multiple displacement amplification (MDA) for whole genome amplification and linked markers to the RS1 gene. The study evaluates the ability of MDA to amplify the whole genome directly from a single blastomere. MDA products were used for polymerase chain reaction analysis of two polymor...

متن کاملWhat next for preimplantation genetic screening? A polar body approach!
Screening of human preimplantation embryos for numerical chromosome abnormalities has been conducted mostly at the preimplantation stage using fluorescence in situ hybridization. However, it is clear that preimplantation genetic screening (PGS) as it is currently practiced does not improve live birth rates. Therefore the ESHRE PGS Task Force has decided to start a proof of principle study with ...
متن کاملPreimplantation diagnosis in Switzerland--birth of a healthy child after polar body biopsy.
In Switzerland preimplantation genetic diagnosis is limited by law to polar body biopsy (PBB). The indications for PBB include unexplained recurrent miscarriage and improvement of the outcome of in vitro fertilisation (IVF) cycles in women at an advanced reproductive age. In this article we report the first birth of a healthy child after polar body biopsy in Switzerland in a case of unexplained...
