Using a combined qualitative-quantitative approach, this renewal project will explore clinicians strategies for communicating prenatal genetics information and service options to Mexican-origin clients in California and Texas, where Mexican-origin women constitute a large and growing proportion of women in prenatal care. The study will focus on clinicians with different professional backgrounds working in diverse practice settings within distinct regulatory contexts.
This project will study the role of patient preferences and other factors in choices regarding use of prenatal screening for and diagnosis of chromosomal disorders in a racially/ethnically diverse population. The study will collect detailed information regarding the distribution of individual preferences for test characteristics and outcomes by racial/ethnic group, as well as other factors which may be related to choices regarding the use of these tests.
This project will investigate the nature of disability to articulate, for public policy, the purposes for which emerging testing capabilities ought ethically to be used. To analyze the nature of disability, the project participants--including experts from disability studies, medical geneticists, genetic counselors, philosophers, and others--will examine two distinctions that are not well addressed in the literature: the distinction between nondisease and disease traits, and the distinction between medical and social disabilities.
An increasing number of genetic carrier screening tests pose a challenge to adequate prenatal patient education. Clinic based computer patient education programs may be an effective response to this challenge. Before mounting a RCT to assess their effectiveness it is essential to study the feasibility of operating such programs in clinic settings. We propose a feasibility study.
This is a competing renewal to continue our investigations of the use of molecular cytogenetic testing by array copy number analysis in prenatal diagnostic testing. We have completed a prospective blinded comparison of copy number analysis (aCNA) with standard conventional karyotyping in 4400 unselected prenatal diagnostic tests. Our work demonstrates that aCNA identifies all pathologic findings seen by karyotyping and provides significant incremental information in 2% of all patients tested.
Most, if not all, human diseases have one or more genetic factors that contribute to cause, likelihood of occurrence, severity, and response to existing or experimental treatments. There is a general perception that the ability to define a person's genetic makeup will lead to better health, improved treatments and a better understanding of risks to other family members. However, many genetic technologies increase uncertainty and confusion in the minds of patients, relatives, doctors, health insurers and others.
The objective of this project is to address the content, timing, efficacy, and impact of prenatal education about newborn screening generally and bloodspot sample retention specifically. This project has the following specific aims: Specific Aim 1) To determine what pregnant women, young mothers, and their partners want to know regarding the retention and use of residual bloodspot samples ' Methods include 15 focus groups conducted in five states (NY, CA, UT, MN, WA).
Recent advances in genomic medicine and genetic testing have increased availability of and access to genetic assessments in both specialty and routine clinical care. Isolation of genetic markers for disease risk among healthy individuals is changing the way in which diseases are detected and defined. Media reports of genetic findings and availability of direct-to-consumer tests may increase both public curiosity and concern.
Noninvasive prenatal genetic testing, which utilizes cell-free fetal DNA and advances in sequencing technology, is revolutionizing the practice of obstetrics. While currently used as a screen for a limited number of aneuploidies and genetic conditions, noninvasive testing is anticipated to employ whole fetal exome and genome sequencing to identify not only monogenic disorders but also microduplications, microdeletions, and variants of uncertain clinical significance.
Prenatal testing is evolving in two important ways: first, advances in genomic medicine mean that samples of fetal DNA obtained with invasive methods (such as amniocentesis) can be analyzed using microarray analysis or whole genome sequencing, revealing far more information about the fetus's genetic make-up than was previously possible; and second, new, non-invasive prenatal tests have been introduced that isolate fragments of fetal DNA circulating in a pregnant woman's blood, making possible safe, highly accurate genetic testing much earlier in pregnancy than was previously possi
