Background: Genetics research over the past 20 years has helped researchers find the causes of many diseases. More powerful tools for genetic testing now exist. Researchers want to use these new tools to learn more about genetic diseases. They want to look for possible genetic causes of unusual diseases. They will focus on people who live outside of the United States and whose access to genetic testing has been limited. Objective: To look for potential genetic sources of diseases among children and their families. Eligibility: Children aged 2 to 18 years and their related family members who have or may have a genetic disease. They will reside primarily outside of the US. Design: Participants will be recruited at sites outside of the US. Participants will be screened. Their existing medical records will be reviewed. They will have a physical exam. They will answer questions about their family history and symptoms. Participants will provide samples for genetic testing. They may have blood drawn. They may spit saliva into a small container. They may have a cotton swab rubbed on the inside of the mouth. The samples will be shipped to the NIH for genetic testing. Participants will be notified if testing reveals a known disease. Participants may be asked to provide new samples to confirm the diagnosis. Local study teams will contact the participants about the results. Participants will also be notified if analysis yields gene variants that may cause disease.
NCT07247279

NCT02814747
After the use of DNA chips for diagnostic purposes, high-throughput sequencing (HTS) is transforming the field of developmental diseases, from fundamental research to care. Nonetheless, before HTS can be transferred to everyday clinical practice, in particular for expert diagnosis using exome HTS, it is necessary to anticipate the nature of the information to be given to patients and to parents in order to obtain consent for exome HTS. The objective in terms of public health is to allow patients with rare diseases to benefit from innovative technologies in optimal conditions of information and accompaniment. the objectives of this project are to 1. evaluate the preferences of families of patients with development disorders as regard to suspicious and incidental findings from HTS before its introduction for diagnostic purpose, 2. and then, following the exome analyses carried out for diagnostic purposes, describe, analyse and understand the experience, expectations and reactions of families and geneticists concerning the diagnostic trajectory in general and at the time the results of the HTS were announced in particular A methodology that associated quantitative and qualitative approaches was chosen so as to combine the advantages and overcome the shortcomings of each: a quantitative study to investigate a large number of patients, which would ensure a certain representativeness of the population and allow sub-groups analyses to study the upstream phase concerning indications for high-throughput sequencing; and a qualitative study, which though it allows only a small number of patients to be investigated, makes it possible to describe, analyze and understand in depth the complex downstream phenomena of high-throughput sequencing results
NCT07102966
The purpose of this study is to provide advanced genetic testing and virtual consultations for seriously ill newborns in hospitals in Texas with fewer resources, especially along the Texas-Mexico border. The researchers also want to know how well the virtual consultation tool, called Consultagene, works in these hospitals by gathering feedback from healthcare providers. Researchers will provide rapid whole genome sequencing (WGS) to 200 infants over a period of 5 years. Data will be collected via Consultagene, surveys, and qualitative interviews.
NCT06573723
The goal of this observational study is to create a single macro registry system with data collection on common clinical features, grouping the different rare diseases (RD). Moreover, the specific goals are to generate an alert system for possible cases of RD with data from the electronic medical record, to describe the occurrence of RD in the evaluated population, to characterize the population, to describe patterns of diagnosis and treatment of RD present at the time, and to explore patient-reported outcomes.
NCT05070988

NCT05913843
There are more than 7000 known genetic disorders, and the number of affected is estimated to be about 6-10% of the population. Around 30 to 40% of genetic disorders have physical changes in the face and skull such as Down's syndrome or Fragile X syndrome. Therefore, the known facial phenotype of many genetic disorders is highly informative to clinical diagnosis. Since a large number of genetic diseases are associated with special facial phenotypes that are difficult to remember, automated facial analysis such as Face2Gene and GestaltMatcher can assist in the identification and diagnosis of facial phenotypes related to various genetic diseases. Although the current advances in whole exome sequencing (whole exome sequencing) or whole genome sequencing (whole genome sequencing) have greatly improved the diagnostic rate of genetic diseases, about half of the patients are still undiagnosed. For patients with special facial phenotypes, the investigators believe that by combining automated facial analysis and whole exome sequencing data, it should be possible to provide a fast and accurate diagnostic model of genetic mutations for genetic diseases. GestaltMatcher Database is a medical imaging database of rare diseases developed by Professor Peter Krawitz of the University of Bonn, Germany. The database's artificial intelligence module will infer a patient's possible diagnosis based on the patient's photo, age, gender, race, and clinical description. The database will be open to medical researchers in related fields to improve the diagnosis of rare diseases. The investigators will use GestaltMatcher to assist in the diagnosis of patients, and compare the accuracy and significant differences in facial deformities between Taiwanese patients and patients from different countries. And use Eye Tracker to analyze how doctors diagnose patients through facial photos, and compare whether there are significant differences between foreign patients and Taiwanese patients in the diagnosis literature of Taiwanese doctors. The project will also analyze how genetic doctors at the University of Bonn in Germany diagnose patients, and compare it with Taiwanese doctors to better understand the differences in the process of doctors diagnosing patients and ethnic backgrounds.
NCT06144957
SLC13A5 deficiency (Citrate Transporter Disorder, EIEE 25) is a rare genetic disorder with neurodevelopmental delays and seizure onset in the first few days of life. This natural history study is designed to address the lack of understanding of disease progression. Additionally it will identify clinical and biomarker endpoints for use in future clinical trials.
NCT05499091
Next generation sequencing (NGS) allows some better diagnostic results, particularly, in the rare diseases field. At a twenty five percent rate, those exams highlight some variants which are not yet described in human pathology. The relationship between a variant found inside a candidate gene and a pathology, is able to be confirmed by functional studies at a protein level. This study aims to build a biological collection to feed further functional studies to confirm the relationship between NGS identified variants, and the clinical signs and symptoms.
NCT06721871
a 32-week study that will evaluate the safety, tolerability and preliminary efficacy of multiple ascending doses of crofelemer, compared to placebo, using a randomized cross-over design within each dose level, when administered to participants with MVID receiving parenteral support (PS, defined as TPN with or without supplementary IV fluid requirements). Blinded study drug will be administered as a novel crofelemer formulation, Crofelemer Powder for Oral Solution, or a matching placebo powder formulation for oral solution. Assigned study drug will be reconstituted and administered orally (or enterally) three times daily (TID) as a concentrated liquid formulation in each of the three dose levels
NCT04024774
Most diagnostically unsolved rare disease have a genetic cause. These causes have not been found applying the current methodologies due to technical limitations (e.g. repeat expansions, changes in non-coding (intronic) regions) or, although methodically recorded, their pathophysiological significance but not classified as clinically relevant. A re- and meta-analysis of existing data sets with new algorithms and statistical models as well as the complementation with other omics technologies followed by functional follow-up studies in appropriate disease models (e.g. patient cell lines) allows to elucidate additional causes of diseases and improve the diagnosis of hereditary diseases. In addition to the direct examination of persons affected, the analysis of healthy family members, for example of parents, plays an important role in a so-called trio analysis, especially in the efficient filtering of the extensive data sets for newly created changes, so-called de novo- Variants (new mutations). In the context of the outlined analyzes, new disease genes can be found and validated. The gain of scientific knowledge due to a better understanding of basic cell biological mechanisms can contribute to the development of targeted therapeutic approaches. In this context, the Solve-RD project has been built and financed by the European Union with the ambitions to solve large numbers of rare disease, for which a molecular cause is not known yet by sophisticated combined omics approaches, and to improve diagnostics of rare disease patients. Solve-RD fully integrates with the newly formed European Reference Networks (ERNs) for rare diseases, and in particular the ERN-RND, -EURO-NMD, -ITHACA, and -GENTURIS. The AnDDI-Rares network is fully affiliated to the ERN ITHACA network and will actively contribute to the project, by the ambition of sharing knowledge about genes, genomic variants and phenotypes. The project will first reanalyse 18.000 negative exomes from the different ERNs performed in a diagnostic or research context (collection of biomaterial, clinical/phenotypic data plus next-generation sequencing has already been performed, and the patient/family has agreed previously in writing that their sample could be used for research related to their disease, with no study related presence required. The project will also propose new multi-omics analyses with new samples needed in 500 patients and their parents in total, justifying the AnDDI-Solve-RD project.

NCT04339465
Families of children with rare diseases (i.e., not more than 5 out of 10.000 people are affected) are often highly burdened with fears, insecurities and concerns regarding the affected child and his/her siblings. The project at hand will test two innovative forms of care (CARE-FAM and WEP-CARE) at 17 sites in 12 federal states of Germany. The goal is to improve the mental health and quality of life of children affected by rare diseases and their relatives in a sustainable manner. If successful, these interventions will be introduced into regular care.
NCT03491280
The DiRiP study will enroll patients (n = 3500) with unclear rare diseases and suspected genetic reasons. In group 1 (n = 500) subjects are clinically characterized in the context of outpatient/ inpatient standard care at the UKT or cooperating location, NGS analyzes and other omics analyzes (transcriptomics, proteomics, metabolomics), functional cell biology studies will be performed. In group 2 diagnostics is already performed. The DiRiP-study fully integrates with the newly formed European Reference Networks (ERNs) for rare diseases, and in particular the ERN-RND, -EURO-NMD, -ITHACA, and -GENTURIS.
NCT03321604
In this study, Investigators will conduct a prospective cohort study of dialysis patients by collecting research-quality information on patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data. Investigators will utilize data from the cohort to test the independent relationship between biochemical and genetic markers and Fabry disease and other rare diseases.
NCT02724995
This study will help the investigator understand the pathogenesis of different rare genetic conditions and to establish database of rare genetic databases. This would ultimately help to provide more accurate diagnosis through advanced genomic diagnostic testing and databases established from this study. This knowledge would in turn help in the clinical management of other affected family members and other individuals affected with similar conditions. Understanding of pathogenesis of the disease would also enable the investigator to develop targeted therapies for rare genetic diseases, and also to collaborate on the targeted therapy-related clinical trials. The investigator plans to store the results of this study in databases. These results will be shared with other researchers or doctors, who research, diagnose or treat the individuals with similar diseases. The investigator will only share the data that is collected and not the biological samples.
