Filter by:Advancements in prenatal genetic screening have significantly improved the identification of chromosomal abnormalities and heritable conditions during pregnancy, yet current standards for patient education in this domain are largely ineffective. The most effective approach to education about prenatal screening is one-on-one genetic counseling, but due to the limited number of counselors this is not feasible, especially in rural and frontier areas. The investigators will address this national problem using a novel education game that can more effectively address this gap in healthcare decision-making.
An important aspect of successful genomic medicine implementation is developing effective approaches for screening at-risk family members after probands are identified, also known as cascade screening. Most cascade screening studies conducted to date have been conducted outside the US, and very few studies have used a rigorous approach involving a comparator group or randomized controlled design. A major question in the field is how to most effectively implement cascade screening, given commonly cited communication barriers, while respecting privacy among probands and family members. This study will conduct a randomized controlled trial to assess direct contact of relatives by study team members vs indirect, or proband-initiated, contact. We will assess efficacy of the cascade screening intervention, patient-centered outcomes regarding mental, physical, and psychosocial outcomes in probands and family members, and implementation evaluation outcomes. Individuals who are known to carry the KCNQ1 Met224Thr or APOB Arg3527Gln variant will be eligible to participate. After providing consent and being deemed eligible, individuals will be randomized in a 1:1 manner into the direct or indirect contact of family members arm of the study. The randomization will be stratified by variant to ensure equal representation of each variant in the study arms. Individuals in the indirect arm will be instructed to contact their first-degree family members about the opportunity to be screened. They will be provided with a disease-specific pamphlet and a family letter explaining the cascade screening. In the direct arm, probands will be advised that the study staff will be contacting their family members. They will be instructed to also contact their family members prior to the study team contacting them. Approximately two weeks after this meeting with the proband, the study staff will mail letters to eligible first-degree family members of the probands. If we do not hear back from individual family members, we will follow-up with another letter, telephone call, or home visit. The information contained in the letters will be the same information for both the direct and indirect arms of the study. All interested family members will receive pre-test counseling and free, in-home, saliva-based genetic testing, and post-test counseling.
The goals of this study are: To assess the impact of genetic testing for Age-related Macular Degeneration (AMD) on lifestyle behaviors as measured by systemic and ocular carotenoid status.
The overall study objective of this trial study is to identify and evaluate strategies to improve the accessibility of the video education with result dependent disclosure (VERDI) model, increasingly utilized as a pre-genetic testing (pretest) education alternative in clinical practice, to better serve a more diverse patient population at risk for hereditary cancers.
Determine the effect of a culturally sensitive prenatal genetic testing (PGT) education intervention delivered via a mobile application on pregnant women's perceptions, knowledge, and uptake of PGT. Our working hypothesis, based on prior studies, is that pregnant women who receive a culturally sensitive intervention to enhance their knowledge and understanding of PGT will feel more confident in their decision-making regarding PGT.
The study aims to investigate the difference of in vitro fertilization (IVF) outcomes among non-invasive PGT-A, PGT-A and combined non-invasive PGT-A and PGT-A.
To date, there are highly effective lipid-lowering drugs, the combination of which makes it possible to achieve the target level of LDL-C in most patients with familial hypercholesterolemia (FH). However, the effectiveness of treatment of FH patients strongly depends on adherence to lipid-lowering therapy and to the healthy lifestyle, as well as the detection of the disease and the therapy prescription as early as possible, better in childhood. The aim of the study is to assess the impact of genetic testing and motivational counseling on the effectiveness of treatment and cascade screening in patients with FH.
Recent recommendations to return children's results for adult-onset conditions to parents anytime whole exome or genome sequencing is performed, as well as growing expectations to return research results to participants on a large-scale basis, mean adolescents will increasingly be engaged in assenting (<age 18) and consenting (>age 18) to return of genomic research results. There is an urgent need to understand adolescents' informational preferences and to create ethically informed, scalable processes that empower adolescents from diverse backgrounds to participate in the decision-making process about learning genomic results. This research will provide important insights into adolescents' choices, as well as the ethical, legal and societal implications of engaging adolescents in making choices about learning genomic results in genomic research and community-based research settings.
The purpose of this study is to describe how women with BRCA1/2 mutations react to genetic risk modifier testing, and to examine how they make decisions about their healthcare.
Pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD) is associated with considerable morbidity and even mortality. Next to environmental risk factors, the investigators believe that there is an important role of genetic predisposition to develop PAH in CHD. There often is a discrepancy between the severity of PAH and the CHD, where it is useful to screen for PAH gene mutations. The investigators hypothesize that the genotype is partly responsible for the phenotypic variability in patients with congenital shunt lesions, where some develop PAH and others do not. If a genetic predisposition for PAH in CHD could be identified, then genetic screening could be a useful additional tool for early detection of patients at risk of pulmonary vascular disease and PAH development, with new opportunities for prevention or early treatment.
