Preimplantation genetic diagnosis (PGD) involves testing for specific genetic conditions prior to the implantation [5] of an embryo in the uterine wall. This form of genetic screening has been made possible by the growth of in-vitro fertilization [6] (IVF) technology, which allows for the early stages of development to occur in a laboratory dish rather than in vivo [7]. The purpose of PGD is to...

Inherited genetic diseases have been a problem for some families attempting to conceive a child. If affected parents or carriers of genetic disorders wished to avoid transmitting a condition to their child, they can choose to have prenatal diagnosis of their foetus. Amniocentesis or chorionic villus sampling enables cells from the foetus to be collected and sent for genetic analysis. They could...

Preimplantation genetic diagnosis (PGD) is a reproductive technology used with an in vitro fertilization (IVF) cycle to increase the potential for a successful pregnancy and delivery. The most common applications for PGD include testing for extra or missing chromosomes (aneuploidy screening), familial structural chromosome rearrangements, and diagnosis of genetic disease in couples of increased...

This article covers the rapidly advancing field of preimplantation genetic diagnosis (PGD), the molecular genetic analysis of cells taken from embryos formed through in vitro fertilization (IVF). The article focuses on current practices in patient management, relevant IVF and PGD procedures, molecular methods used in the genetic analysis, and technical difficulties that can affect test results....

The entire human genome will be completely analyzed very shortly and mankind must resolve the issue of how this knowledge will be applied to general medical care in the 21st century. Due to the progress which has hitherto been achieved in gene analysis technology, genetic testing for carrier detection, pre-implantation diagnosis, prenatal diagnosis, presymptomatic diagnosis, predispositional te...

INSTRUCTIONS FOR USE Coverage Positions are intended to supplement certain standard CIGNA HealthCare benefit plans. Please note, the terms of a participant’s particular benefit plan document [Group Service Agreement (GSA), Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] may differ significantly from the standard benefit plans upon which th...

Genetic disorders are a major cause of miscarriage and fetal death. Pre-implantation genetic diagnosis (PGD) can be used to diagnose genetic defects before pregnancy has occurred by creating embryos by IVF, then removing single cells which are genetically analysed using FISH or PCR. Although successful, the techniques have many difficulties because they are highly specialised and at the extreme...

In Denmark, preimplantation genetic diagnosis (PGD) is offered within the public healthcare to families with a known risk of an inherited disease in a child - as an alternative to prenatal diagnosis. It is a well-established technique with rather well-described perinatal- and neonatal outcomes, being comparable to what is seen following in vitro fertilization/intracytoplasmic sperm injection (I...
