Testing for clinical robustness, specificity and long-term stability of the biomarker.', 'detailedDescription': "Hurler disease - MPS I- (mucopolysaccharidosis I) is an inherited lysosomal storage disorder caused by a deficiency of alpha-L-iduronidase, a lysosomal enzyme normally required for the breakdown of certain complex carbohydrates known as glycosaminoglycans (GAGs). If the enzyme is not present in sufficient quantities, the normal breakdown of GAGs is incomplete or blocked. The cell is then unable to excrete the carbohydrate residues and they accumulate in the lysosomes of the cell. This accumulation disrupts the cell's normal functioning and gives rise to the clinical manifestations of the disease.\n\nThe incidence of MPS I is estimated to be at about 1 in 100,000 births. It is inherited in an autosomal recessive manner, affects males and females equally, and in most cases, both parents of an affected child are asymptomatic carriers of the disease. Types of MPS I. Children diagnosed with MPS I have historically been classified into one of three categories based on the severity of their symptoms and rate of disease progression. It has now become clear, however, that there is a wide spectrum of severity in MPS I with much overlap between the categories.\n\n• Hurler Syndrome: The most severe form of MPS I is characterized by progressive developmental delay and severe progressive physical problems. Death often occurs before 10 years of age.\n\n• Hurler-Scheie Syndrome: The intermediate form of MPS I is characterized by normal or near normal intelligence but more severe physical symptoms than those with Scheie Syndrome.\n\n• Scheie Syndrome: The attenuated form of MPS I is characterized by normal intelligence, usually normal height, and milder physical problems than Hurler-Scheie. These individuals potentially have a normal life span.\n\nPatients present within the first year of life with musculoskeletal alterations including short stature, dysostosis multiplex, thoracic-lumbar kyphosis, progressive coarsening of the facial features including large head with bulging frontal bones, depressed nasal bridge with broad nasal tip and anteverted nostrils, full cheeks and enlarged lips, cardiomyopathy and valvular abnormalities, neurosensorial hearing loss, enlarged tonsils and adenoids, and nasal secretion. Developmental delay is usually observed between 12 and 24 months of life and is primarily in the speech realm with progressive cognitive and sensorial deterioration. Hydrocephaly can occur after the age of two. Diffuse corneal compromise leading to corneal opacity becomes detectable from three years of age. Other manifestations include organomegaly, hernias and hirsutism. MPS1 syndrome is caused by mutations in the IDUA gene (4p16.3) leading to complete deficiency in the alpha-L-iduronidase enzyme and lysosomal accumulation of dermatan sulfate and heparan sulfate. Transmission is autosomal recessive. Early diagnosis is difficult because the first clinical signs are not specific, but it is very important to allow early treatment. Diagnosis is based on detection of increased urinary excretion of heparan and dermatan sulfate by 1, 9-dimethylmethylene blue (DMB) test and glycosaminoglycan (GAG) electrophoresis, and demonstration of enzymatic deficiency in leukocytes or fibroblasts. Genetic testing is available. Differential diagnoses include the milder form of mucopolysaccharidosis type 1, the MPS1-Scheie syndrome, although this form is associated with developmental delay with only slight cognitive impairment.\n\nNew methods, like mass-spectrometry give a good chance to characterize specific metabolic alterations in the blood (plasma) of affected patients that allow diagnosing in the future the disease earlier, with a higher sensitivity and specificity.\n\nTherefore it is the goal of the study to identify and validate a new biochemical marker from the plasma of the affected patients helping to benefit other patients by an early diagnose and thereby with an earlier treatment.\n\nThough MPS1 disease is a pan-ethnic disorder, the prevalence of this autosomal-recessive disorder is elevated in countries with a higher frequency of consanguinity. Therefore, we estimate that every 400th newborn in Arabian countries may be eligible for inclusion due to high-grade suspicion of MPS1 disease, while approximately every 2000th newborn in a non-Arabian country may be eligible."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '2 Months', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Patients with Hurler disease or high-grade suspicion for Hurler disease', 'healthyVolunteers': False, 'eligibilityCriteria': 'INCLUSION CRITERIA\n\n* Informed consent will be obtained from the parents before any study related procedures.\n* Patients of both gender older than 2 month\n* The patient has a diagnosis of Hurler disease or a high-grade suspicion for Hurler disease\n* High-grade suspicion present, if one or more inclusion criteria are valid:\n\n 1. \\- Positive family anamnesis for Hurler disease\n 2. \\- Macrocephaly\n 3. \\- Deformed bones and stiff joints, especially the spine, hips, knees, wrists and fingers\n 4. \\- Musculoskeletal alterations including short stature\n 5. \\- Developmental delay and/or progressive mental deterioration\n\nEXCLUSION CRITERIA\n\n* No Informed consent from the parents before any study related procedures.\n* Patients of both gender younger than 2 month\n* No diagnosis of Hurler disease or no valid criteria for profound suspicion of Hurler disease'}, 'identificationModule': {'nctId': 'NCT02298712', 'acronym': 'BioHurler', 'briefTitle': 'Biomarker for Hurler Disease (BioHurler)', 'organization': {'class': 'INDUSTRY', 'fullName': 'CENTOGENE GmbH Rostock'}, 'officialTitle': 'Biomarker for Hurler Disease - An International, Multicenter, Epidemiological Protocol', 'orgStudyIdInfo': {'id': 'BHUR 06-2018'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Observation', 'description': 'Patients with Hurler disease or high-grade suspicion for Hurler disease'}]}, 'contactsLocationsModule': {'locations': [{'zip': '89075', 'city': 'Cairo', 'country': 'Egypt', 'facility': "Children's Hospital, Faculty of Medicine, Ain Shams University", 'geoPoint': {'lat': 30.06263, 'lon': 31.24967}}, {'zip': '18055', 'city': 'Rostock', 'country': 'Germany', 'facility': 'Centogene AG', 'geoPoint': {'lat': 54.0887, 'lon': 12.14049}}, {'zip': '682041', 'city': 'Kochi', 'state': 'Kerala', 'country': 'India', 'facility': 'Amrita Institute of Medical Sciences & Research Centre', 'geoPoint': {'lat': 9.93988, 'lon': 76.26022}}, {'zip': '400705', 'city': 'Mumbai', 'country': 'India', 'facility': 'Navi Mumbai Institute of Research In Mental And Neurological Handicap (NIRMAN)', 'geoPoint': {'lat': 19.07283, 'lon': 72.88261}}, {'zip': '00800c', 'city': 'Colombo', 'country': 'Sri Lanka', 'facility': 'Lady Ridgeway Hospital for Children', 'geoPoint': {'lat': 6.93548, 'lon': 79.84868}}], 'overallOfficials': [{'name': 'Peter Bauer, Prof.', 'role': 'STUDY_CHAIR', 'affiliation': 'Centogene GmbH'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'CENTOGENE GmbH Rostock', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
