Filter by:Transversal multicentric French study on the microbiota in patients with Crohn's disease and their first degree healthy relatives The primary objective is the comparison of microbiota between patients with CD, healthy controls non genetically linked and first degree healthy relatives of patients with CD.
Background: - The purpose of this study is to identify changes in genes that cause human diseases. We would like to obtain some of you or your child s DNA and test for changes in genes that may contribute to a disease in you or your family. Objective: -To allow for exomic or genomic sequencing of NICHD patients or family members in order to identify changes in genes that cause or contribute to a specific disease. Eligibility: - Children who are enrolled in an NICHD clinical study where the condition being studied may have a genetic cause. - Family members of a child who is eligible for this study. Design: - Children and family members will supply DNA samples. If the samples are already available, no further DNA will be needed. - If DNA is not available, samples of either blood or skin will be taken. - We will use these samples with new DNA sequencing technology that looks at all the human genes we know about. This is known as exome and genome sequencing.
Individuals living in geographically underserved areas encounter considerable barriers to access of quality cancer genetic services. Although in-person genetic counseling has generally been accepted as the standard of care, the use of telecommunications to deliver clinical genetic services may help reduce this disparity in access to such services. However, before the widespread adoption of telephone-delivered cancer genetic services occurs, it is critical to analyze the efficacy and safety of this mode of communication. This two-group randomized equivalency/non-inferiority trial will determine whether telephone-based cancer genetic counseling is an acceptable alternative to the traditional in-person mode among women who have a personal or family history of breast and/or ovarian cancer strong enough to warrant genetic counseling and testing. This study's findings will provide important information to cancer centers and cancer control policies about the safety, efficacy, and costs of delivering telephone-based clinical cancer genetic services for geographically challenged women at risk for having Breast Cancer susceptibility gene (BRCA) 1/2 mutations.
