Rare diseases are often synonymous with difficulties for sufferers, whether physical, mental or social. Patients suffering from rare diseases face specific problems, such as the long wait for a diagnosis, the geographical distance between the rare disease reference center and home, and the isolation created by this very disabling disease... Children suffering from rare genetic diseases have difficulty accessing higher education, but above all in finding an internship or work-study placement, due to the rarity of their disability. The aim of this study, entitled "Imagine La Suite", is to assess the difficulties encountered by young people with rare genetic diseases and disabilities in their search for vocational and university training or employment.

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.

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

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.

NCT06343558
Rare and very rare neurological diseases primarily or exclusively affect the nervous system with a prevalence of \< 5 out of 10'000 and 100'000 people, respectively. Besides these, there are undiagnosed neurological diseases: neurological conditions without a diagnosis after completing a full diagnostic examination. Rare, very rare, and undiagnosed neurological diseases are complicated and progressive and often cause variegated motor signs, impairments, and syndromes. Balance and gait are frequently affected in these conditions, already at the clinical examination. These balance and gait impairments limit activities and cause an increased risk of falling. Falls can eventually result in injuries, even severe. There are only a few studies about these diseases, likely because of their rarity. Hence, the clinical presentation and the course of rare and very rare diseases are poorly known or even unknown. Essential information for these conditions' diagnosis, prognosis, treatment and rehabilitation is missing. MaNeNeND is an observational study underway at the Fondazione IRCCS Istituto Neurologico "Carlo Besta" (Milano) aimed at detailing the clinical and biological features of very rare and undiagnosed neurological diseases. Research questions: 1. Do patients with rare (Ra), very rare (V) and undiagnosed (U) neurological diseases suffer a balance and gait impairment? 2. Is there a correlation between the clinical and instrumental severity of the balance and gait impairment in RaVU neurological diseases? 3. Are instrumental measures more sensitive in detecting balance and gait impairments in patients affected by a RaVU neurological disease than the clinical measures? 4. Do the balance and gait impairments in RaVU neurological diseases worsen in time? The current project aims at diagnosing, quantifying and detailing the balance and gait impairment in rare, very rare and undiagnosed neurological diseases. To this aim, questionnaires, clinical scales and instrumental tests will be administered to these patients to collect a wide range of balance and gait measures. These measures will also integrate those collected with MaNeNeND to provide a more detailed description of patients with rare, very rare and diagnosed neurological diseases. Participants will complete two questionnaires: the Dizziness Handicap Inventory - short form (DHI-sf, an ordinal score of self-perceived balance) and the Modified Fatigue Impact Scale (MFIS, an ordinal score of self-perceived fatigue). Moreover, a clinician will administer the Mini Balance Evaluation Systems Test (Mini-BESTest, an ordinal score of balance), the 10 m walking test (for measuring the gait speed and other gait parameters) and the Timed Up and Go test (an instrumental measure of mobility and balance). Walking and the Timed Up and Go tests will be recorded with a trunk-worn inertial measurement unit. Finally, participants will be asked to complete an instrumental upright stance and gait assessment, the first consisting of standing on posturographic plates and the second of walking on a treadmill equipped with force sensors. When walking on the treadmill, an optoelectronic system will also record the position in time of limbs and trunk. The quantification of the severity of the balance and gait impairment of the patients suffering a rare, very rare or undiagnosed neurological disease will highlight these persons' therapeutic and rehabilitative needs. Comparing the balance and gait impairment of rare, very rare and undiagnosed diseases with those of multiple sclerosis, Parkinson's disease and peripheral neuropathy will highlight if the formers' balance and gait impairment has unique characteristics that could help ease the diagnosis of these uncommon conditions. The longitudinal measurements on rare, very rare and undiagnosed diseases will be paramount to identifying prognostic factors. In addition, the data collected in the current study will be crucial for future studies, for example, for estimating the sample size in 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.

NCT04586075
The primary purpose of this study is to discover new disease genes for rare Mendelian disorders and its secondary purpose include diagnosing people with rare genetic disorders that have not been previously diagnosed through conventional clinical means, learning more about the pathobiology of genetic disorders, and developing novel diagnostic technologies and analytics. 500 participants with undiagnosed and suspected genetic disorders will be recruited.
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.
NCT06782230
Rare diseases (RDs) have been defined by the European Union (EU) as life-threatening or chronically debilitating conditions affecting less than 1 person in 2000. RDs are complex and often need special treatments, thus combined efforts are required to address them to improve diagnosis, care and prevention. To date, over 6.000 RDs are known and most of them are \&amp;#34;orphans\&amp;#34;. They do not have a market large enough to gather support to sustain research and discover treatments. Most RDs are disabling, incurable, painful and cause great suffering. Their complexity and heterogeneity often make diagnosis difficult; 25% of RD patients experience a diagnostic delay of 5 to 30 years and this has important implications for patient care. Thus, new diagnostic and therapeutic strategies are urgently needed. RDs registries are increasingly recognized as an effective tool to advance RD research. They are necessary to bring together patients and to pool data to achieve a sufficient sample size to facilitate epidemiological and/or clinical research. It is well known that registries are more effective when annexed to biobank infrastructure since make an important contribution to identify and validate biomarkers, uncover novel genes, elucidate pathogenesis at the Omics level, and develop new therapeutic strategies. Biobanks serve as biological samples and related clinical data repositories from affected patients and from undiagnosed patients experiencing with the \&amp;#34;diagnostic odyssey\&amp;#34;, with the view of a retrospective diagnosis. The aim of creating a biobank is to make available a significant number of well-characterized and properly preserved samples and related data, to the scientific community for large-scale studies. Indeed, the recent advances in the technology of molecular biology and genetics require a large number of properly preserved biospecimens. This is certainly facilitated by building biobank networks. To this regard, in Italy, the collection of RDs samples is fragmented. The existing RD biobanks are of small or medium-size. They are stand-alone collections since only a limited networking among these infrastructures has been organized up to now. The objectives of this project will be: Aim 1: Establishment of the Scattered RD Biobank as a network of RD biobanks in order to overcome RD biological sample scarcity and to collect samples and data of high quality available to the scientific community for future collaborative studies in national and international co-operations Aim 2: Harmonization, Standardization and Network Governance. According to the document ISO 20387 illustrating the general requirements for biobanking, Standard Operating Procedures (SOPs) will be defined to ensure that every biobank in the network strictly follows the entire processes of collection, preparation, storage and distribution of biological material as well as related information and data. Common data bases and ethical/legal documents will be also generated. Aim 3: RD biobank upgrading and creation of novel RD biobanks. Already existing RD biobanks will be implemented in terms of organization of the sample collections according to the common SOPs and of extension of the sample collections and novel RD biobanks will be created such as Huntington\&amp;#39;s disease (OU3 and OU4), Marfan Syndrome, Hereditary Angioedema and Congenital Heart Diseases (OU1) biobanks. All the OU participating to this project are Reference Centre or Biological Research Centre (BRC) for RDs.
