Cytogenetics of recurrent pregnancy loss

Cytogenetics of recurrent pregnancy loss The contribution of chromosomal abnormalities to recurrent pregnancy loss (RLP) is reviewed in the paper. Data from conventional cytogenetic analysis of the karyotype of parents and spontaneous abortions, as well as the results of molecular cytogenetic investigations and preimplantation genetic diagnostics, are discussed. Information about the significance of epigenetic impairments (abnormalities of imprinting and X-chromosome inactivation) for recurrent pregnancy loss is also considered. Cytogenetic analysis of products of conception enables ascertainment of the causes of embryonic death in a large proportion of families, more accurate estimation of the therapeutic efficiency of treatment and drugs (when women with abnormal embryos were excluded), and a statistically valid prognosis about the next pregnancy outcome. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The contribution of chromosomal abnormalities to recurrent pregnancy loss (RLP) is reviewed in the paper. Data from conventional cytogenetic analysis of the karyotype of parents and spontaneous abortions, as well as the results of molecular cytogenetic investigations and preimplantation genetic diagnostics, are discussed. Information about the significance of epigenetic impairments (abnormalities of imprinting and X-chromosome inactivation) for recurrent pregnancy loss is also considered. Cytogenetic analysis of products of conception enables ascertainment of the causes of embryonic death in a large proportion of families, more accurate estimation of the therapeutic efficiency of treatment and drugs (when women with abnormal embryos were excluded), and a statistically valid prognosis about the next pregnancy outcome.
