Outcome of preimplantation genetic diagnosis of translocations.
OBJECTIVE To review 35 cases of preimplantation genetic diagnosis (PGD) of translocations with several methods, including telomeric probes. DESIGN Retrospective study. SETTING Clinical IVF laboratory. PATIENT(S) Thirty-five couples with one partner carrying a chromosomal translocation. INTERVENTION(S) PGD of translocation after polar-body or embryo biopsy. MAIN OUTCOME MEASURE(S) Preg...
متن کاملIntroduction to preimplantation genetic diagnosis
Preimplantation genetic diagnosis (PGD) was • fi rst applied in 1988 using a polymerase chain reaction (PCR) protocol to amplify a sequence on the Y chromosome for embryo sexing for patients carrying X-linked disease. Patients have to go through in vitro • fertilization (IVF) so that their embryos may be generated in vitro. Cells are removed from oocytes or embryos and used for the genetic diag...
متن کاملPreimplantation Genetic Diagnosis for Aneuploidy and Translocations Using Array Comparative Genomic Hybridization
At least 50% of human embryos are abnormal, and that increases to 80% in women 40 years or older. These abnormalities result in low implantation rates in embryos transferred during in vitro fertilization procedures, from 30% in women <35 years to 6% in women 40 years or older. Thus selecting normal embryos for transfer should improve pregnancy results. The genetic analysis of embryos is called ...
متن کاملMeiotic segregation of Robertsonian translocations ascertained in cleavage-stage embryos--implications for preimplantation genetic diagnosis.
BACKGROUND The aim of this study was to ascertain the prevalence of meiotic segregation products in embryos from carriers of 13/14 and 14/21 Robertsonian translocations and to estimate the predictive value of testing single cells using the fluorescence in situ hybridization (FISH) technique, to provide more information for decision-making about PGD. METHODS In this prospective cohort study, t...
متن کاملPreimplantation 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...
