These rare diseases are characterized by a triple heterogeneity (clinical, genetic and molecular), which made them unreachable by traditional molecular diagnostic sequencing technology by the large number of genes to be tested (\\> 190).\n\nThe advent of high-throughput sequencing (NGS) and targeted capture has opened unexpected possibilities of investigation and ultimately to improve the care of patients. This project aims to study the genetic and molecular epidemiology of an interregional french (grand EST) cohort of patients. Patients receive a detailed retinal phenotype (visual acuity, visual field, photographs of the fundus and ERG). Their DNA will be analyzed by NGS targets the 190 known genes (https://sph.uth.edu/retnet/).\n\nThis research will provide a molecular epidemiological cohort study compared to prior publications on the frequency of genes involved. The benefit for patients is important to: establish a mode of transmission of the disease and optimize genetic counseling (currently very empirical); establish phenotype-genotype correlations in the French population (very few studies to date) and from the data of international literature; identify patients likely to be included in future therapeutic protocols of research; identify patients with significant potential for future projects to identify new genes.\n\nThe primary purpose of the protocol is to use high throughput sequencing to identify pathogenic variants in genes involved in RP.\n\nThe secondary purposes will be the following:\n\n* Determining the diagnostic yield\n* Study the genotype-phenotype correlation.\n\nThe secondary purposes will be the following:\n\n* Determining the diagnostic yield\n* Study the genotype-phenotype correlation'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '2 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients with an RP and/or having a family history of RP', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subject of both sex, aged at least 2 years, being diagnosed with an RP, and/or having a family history of RP\n* Informed about the results of the preliminary medical visit, or which (s) holder (s) parental authority or the guardian / curator has (have) was (been) informed\n* Informed consent signed\n* Affiliation to the French health system\n\nExclusion Criteria:\n\n* The patient does not want to participate to the protocol\n* Intercurrent diseases do not allow the practice of tests provided for this protocol\n* Phenocopy\n* Subject excluded or being excluded by another protocol\n* Subject in emergency case\n* Subject under judicial protection'}, 'identificationModule': {'nctId': 'NCT02860520', 'acronym': 'RP-SEQ-HD', 'briefTitle': 'Clinical Implication of Retinitis Pigmentosa Molecular Diagnostic Using High Throughput Sequencing.', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Strasbourg, France'}, 'officialTitle': 'Clinical Implication of the Molecular Diagnostic Retinitis Pigmentosa Molecular Diagnostic Using High Throughput Sequencing (RP-SEQ-HD)', 'orgStudyIdInfo': {'id': '5724'}}, 'contactsLocationsModule': {'locations': [{'zip': '21000', 'city': 'Dijon', 'status': 'NOT_YET_RECRUITING', 'country': 'France', 'contacts': [{'name': 'Catherine CREUZOT-GARCHER, MD', 'role': 'CONTACT', 'email': 'catherine.creuzot-garcher@chu-dijon.fr', 'phone': '33.3.80.29.37.56'}, {'name': 'Catherine CREUZOT-GARCHER, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Alain BRON, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': "Service d'Ophtalmologie CHU Hôpital Général", 'geoPoint': {'lat': 47.31344, 'lon': 5.01391}}, {'zip': '51092', 'city': 'Reims', 'status': 'NOT_YET_RECRUITING', 'country': 'France', 'contacts': [{'name': 'Carl ARNDT, MD', 'role': 'CONTACT', 'email': 'prarndt@gmail.com', 'phone': '33.3.26.78.77.20'}, {'name': 'Carl ARNDT, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Dominique GAILLARD, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': "Service d'Ophtalmologie, Hôpital Robert Debré, CHR", 'geoPoint': {'lat': 49.26526, 'lon': 4.02853}}, {'zip': '67091', 'city': 'Strasbourg', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Hélène DOLLFUS, MD', 'role': 'CONTACT', 'email': 'helene.dollfus@chru-strasbourg.fr', 'phone': '33.3.88.11.67.53'}, {'name': 'Jean MULLER, PHD', 'role': 'CONTACT', 'email': 'jean.muller@chru-strasbourg.fr', 'phone': '03.69.55.11.66'}, {'name': 'Hélène DOLLFUS, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Yaumara PERDOMO, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Affections Rares en Génétique Ophtalmologique (CARGO) Hôpital Civil, Hôpitaux Universitaires de Strasbourg', 'geoPoint': {'lat': 48.58392, 'lon': 7.74553}}, {'zip': '54500', 'city': 'Vandœuvre-lès-Nancy', 'status': 'NOT_YET_RECRUITING', 'country': 'France', 'contacts': [{'name': 'Karine ANGIOI-DUPREZ, MD', 'role': 'CONTACT', 'email': 'k.angioi-duprez@chu-nancy.fr', 'phone': '33.3.15.30.39'}, {'name': 'Karine ANGIOI-DUPREZ, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Bruno LEHEUP, MD', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Philippe JONVEAUX, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': "Service d'Ophtalmologie, CHU BRABOIS", 'geoPoint': {'lat': 48.66115, 'lon': 6.17114}}], 'centralContacts': [{'name': 'Hélène DOLLFUS, MD', 'role': 'CONTACT', 'email': 'helene.dollfus@chru-strasbourg.fr', 'phone': '33.3.88.12.81.19'}, {'name': 'Jean MULLER, PHD', 'role': 'CONTACT', 'email': 'jean.muller@chru-strasbourg.fr', 'phone': '33.3.69.55.11.66'}], 'overallOfficials': [{'name': 'Hélène DOLLFUS, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Hôpitaux Universitaires de Strasbourg'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Strasbourg, France', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
