Benefit of broadened screening of X-linked diseases (XLD): referral trends to preimplantation genetic testing (PGT-M)

Preimplantation 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...

O-27: Preimplantation Genetic Diagnosis in Prevention of Genetic Diseases -Diagnostic of Spinal Muscular Atrophy (SMA)

Background: Preimplantation genetic diagnosis - PGD is currently an established procedure allowing genetic research of oocyte or embryo before implantation to the uterus. Spinal muscular atrophy (SMA) is a neurodegenerative disorder, being the second most common lethal autosomal recessive disease in Caucasians, after cystic fibrosis. There are three clinically different types of which type I (W...

Preimplantation Genetic Screening

In the last 30 years, genetic testing techniques have been developed to identify chromosomally normal embryos in vitro, thereby potentially increasing the proportion of successful cycles with elective single-embryo transfer, and minimizing twin-pregnancy complications and miscarriages. This testing is termed "pre-implantation genetic screening" (PGS), in contrast to preimplantation genetic diag...
