Preimplantation genetic diagnosis for α-thalassaemia in China

First successful preimplantation genetic diagnosis in Singapore--avoidance of beta-thalassaemia major.

INTRODUCTION We report on the first successful preimplantation genetic diagnosis (PGD) in Singapore. CLINICAL PICTURE A couple who are beta-thalassaemia carriers and have an affected daughter requested for PGD. TREATMENT Two cycles of PGD were performed on the couple. Beta-thalassaemia mutations were detected using a nested PCR and minisequencing strategy, and unaffected embryos were select...

Preimplantation Genetic Diagnosis

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)

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...

Preimplantation genetic diagnosis.

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....
