This book was released on 2020-06-22 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birth defects are one of the major public health concerns in the world, as they cause approximately 20% of infant deaths. Genetic disorders, including chromosome abnormalities and single gene disorders, are the most common causes of birth defects for which there is no efficient treatment. Prenatal genetic screening and diagnosis allow early identification of affected conceptuses and facilitates reproduction planning or counseling. Molecular technologies have developed rapidly in recent years and have been widely used in screening and diagnosis of genetic disorders at all stages of prenatal development (e.g. pre-implantation, embryonic and fetal). However, their performance still needs to be validated and assessed as the balance between their advantages and disadvantages need to be discussed. With the ability to detect copy number variations (CNVs), polyploidy, uniparental disomy and maternal cell contamination, SNP-based chromosomal microarray analysis (CMA) is showing the unique importance in diagnosing chromosomal abnormalities. The interpretation of CNVs remains a challenge; however, ultrasound and biochemical screening improve the diagnosis of fetal chromosomal abnormalities. Whole exome sequencing (WES) and whole genome sequencing (WGS) play increasingly significant roles in prenatal and carrier screening for genetic disorders. NGS-based non-invasive prenatal screening (NIPS) is now widely used for detecting common autosomal aneuploidies and has shown the potential of detecting microdeletions and microduplications. However, further investigations of the sensitivity and accuracy are required and large-scale data is necessary to evaluate the performance and clinical applications of current and new methods. Recently, reports of application of newer technologies in prenatal setting became available. Examples include third generation sequencing (reading the nucleotide sequences at the single molecule level), digital PCR (used for direct quantification of DNA) and cell-based NIPT. In the followed listed papers, the authors showed their successful experiences in identifying novel mutation, detecting low-level mosaicism or de novo mutations limited in germline cells, investigating the association of the CNVs with specific phenotypic alterations by using WES, CMA, digital PCR and some other new-developed molecular techniques. More interesting, the authors also presented a report about the evaluation of diagnostic yield in fetal WES, which suggested a new tendency to apply WES or WGS directly for prenatal diagnosis. We believed that the efficiency of scanning causative mutations and prenatal or preimplantion genetic diagnosis for genetic disorders will further improved based on the technologies of whole genomic sequencing with further improved output and resolution. New techniques, such as quick-WES for the newborn in intensive care unit, direct-WGS for prenatal diagnosis and non-invasive test for fetal monogenic disorders, will become available in the near future.

Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.

Download or read book Women and Prenatal Testing written by Karen H. Rothenberg and published by Ohio State University Press. This book was released on 1994 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: "For pregnant women in the 1990s, technological developments have ushered in new and expanding reproductive genetic testing options. Some herald these procedures as advances providing women with previously unavailable information about their pregnancies. Others contend that with this surge of information come increasing and perhaps unwarranted obligations: while some women have greater knowledge about their pregnancies, they also face far more complex decisions and a greater pressure to do as much as is technologically possible to ensure the birth of a healthy child." "This book focuses on the major women's issues surrounding the development and application of reproductive genetic testing. Although much has been written about the biological safety and efficacy of these technologies, few publications have addressed their psychological, sociocultural, ethical, legal, and political impact on women and their experience of pregnancy." "The first of three sections provides the contextual framework in which the debate should be analyzed. The second section sets forth the philosophical foundations and complex ethical and legal questions that need to be addressed, and the final section delineates a variety of perspectives on the psychological and sociocultural issues raised by reproductive genetic testing. These fourteen essays on the cutting edge of the debate are essential reading for anyone interested in women's studies, human genetics, health law; and bioethics and prenatal care providers."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

This book was released on 2017-04-21 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in genetics and genomics are transforming medical practice, resulting in a dramatic growth of genetic testing in the health care system. The rapid development of new technologies, however, has also brought challenges, including the need for rigorous evaluation of the validity and utility of genetic tests, questions regarding the best ways to incorporate them into medical practice, and how to weigh their cost against potential short- and long-term benefits. As the availability of genetic tests increases so do concerns about the achievement of meaningful improvements in clinical outcomes, costs of testing, and the potential for accentuating medical care inequality. Given the rapid pace in the development of genetic tests and new testing technologies, An Evidence Framework for Genetic Testing seeks to advance the development of an adequate evidence base for genetic tests to improve patient care and treatment. Additionally, this report recommends a framework for decision-making regarding the use of genetic tests in clinical care.

Download or read book Focus on Genetic Screening Research written by Sandra R. Pupecki and published by Nova Publishers. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene tests (also called DNA-based tests), the newest and most sophisticated of the techniques used to test for genetic disorders, involve direct examination of the DNA molecule itself. Other genetic tests include biochemical tests for such gene products as enzymes and other proteins and for microscopic examination of stained or fluorescent chromosomes. Genetic tests are used for several reasons, including: Carrier screening, which involves identifying unaffected individuals who carry one copy of a gene for a disease that requires two copies for the disease to be expressed; Preimplantation genetic diagnosis prenatal diagnostic testing new-born screening; Presymptomatic testing for predicting adult-onset disorders such as Huntington's disease; Presymptomatic testing for estimating the risk of developing adult-onset cancers and Alzheimer's disease; and Confirmational diagnosis of a symptomatic individual forensic/identity testing. In gene tests, scientists scan a patient's DNA sample for mutated sequences. A DNA sample can be obtained from any tissue, including blood. probes, whose sequences are complementary to the mutated sequences. These probes will seek their complement among the three billion base pairs of an individual's genome. If the mutated sequence is present in the patient's genome, the probe will bind to it and flag the mutation. Another type of DNA testing involves comparing the sequence of DNA bases in a patient's gene to a normal version of the gene. This book gathers important research in this field.

Download or read book Prenatal Genetic Testing Abortion and Disability Justice written by Amber Knight and published by Oxford University Press. This book was released on 2023-02-22 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The routinization of non-invasive prenatal genetic testing (NIPT) raises urgent questions about disability rights and reproductive justice. Supporters defend NIPT on the grounds that genetic information about the fetus helps would-be parents make better family planning choices. Prenatal Genetic Testing, Abortion, and Disability Justice challenges that assessment by exploring how NIPT can actually constrain pregnant women's options. Prospective parents must balance a complicated array of factors, including the familial, social, and financial support they can reasonably expect to receive if they choose to carry a disabled fetus to term and raise after birth, causing many pregnant women to “choose” termination. Focusing on the US, the book explores the intent and effects of prenatal screening in connection to women's bodily autonomy and disability rights, addressing themes at the intersection of genetic medicine, policymaking, critical disabilities studies, and political theory. Knight and Miller shift debates about reprogenetics from bioethics to political practice, as well as thoroughly critiquing the neoliberal state and the eugenic technologies that support it. Providing concrete suggestions for reforming medical practice, welfare policy, and cultural norms surrounding disability, this book highlights sites of necessary reform to envision how prospective parents can make truly free choices about prenatal genetic testing and selection abortion.
