The development of high-throughput sequencing techniques (next generation sequencing: NGS) has drastically increased the detection of point mutations offering the possibility to test a large number of genes simultaneously. NGS also shows a huge potential in detecting structural variants. The objective of this research is to assess the sensitivity of a simultaneous detection of point mutations and structural variants by NGS approaches. This would bring together in a single step the equivalent of performing an array-Comparative genomic hybridization (CGH) analysis plus performing a targeted sequencing of candidate genes. Investigators will compare two approaches for this simultaneous detection: a targeted enrichment of candidate genes coding regions using probes covering these regions associated with a backbone of genomic probes, an approach that could be implemented immediately in diagnostic at the hospital, and a whole genome sequencing (WGS), that is currently a too expensive tool for routine diagnosis but that should be the approach used in the future. Investigators will compare these two approaches to the traditional one: CGH array + WGS. The implementation of a "one step" strategy to detect both types of mutations (punctual and structural) would accelerate and improve the access of patients to a molecular diagnosis.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '3 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'All patients with intellectual deficit without diagnosis', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with developmental disabilities\n* No etiologic diagnosis but suspected genetic cause\n* Fragile X syndrome research negative\n\nExclusion Criteria:\n\n* Children born to consanguineous couples\n* Diagnosis already established or suspected\n* Identification of an independent etiology'}, 'identificationModule': {'nctId': 'NCT02881333', 'acronym': 'CNV-Seq', 'briefTitle': 'Various Type of Genetic Events in Patients With Intellectual Disability', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Strasbourg, France'}, 'officialTitle': 'Evaluation of Tools for the Simultaneous Detection of Point and Structural Mutations in Patients With Intellectual Disability', 'orgStudyIdInfo': {'id': '6374'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Blood samples', 'type': 'GENETIC'}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Amélie Piton', 'role': 'CONTACT', 'email': 'amélie.piton@chru-strasbourg.fr'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Strasbourg, France', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
