There are different factors that can induce a decrease in the DAO activity, with genetic origin being the main one. Currently, multiple genes have been identified SNPs that can alter the correct functioning of the DAO. The four most relevant SNPs that lead to a reduction in the enzymatic activity of DAO or a transcriptional activity decreased in this are the following: c.47C\\>T (rs10156191), c.995C\\>T (rs1049742), c.1990C\\>G (rs1049793) and c.-691G\\>T (rs2052129). Clinical studies indicate that DAO deficiency has a high prevalence in diseases such as Migraine (87%), fibromyalgia (75%) or attention deficit hyperactivity disorder (ADHD) in children (75%). However, to date no study has been conducted exploring the prevalence gene of DAO deficiency in the general population. Thus, the objective of this study is to estimate the prevalence of genetic DAO deficiency in the population.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '3 Days', 'minimumAge': '0 Days', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Newborns born in Hospital Universitari Genreal de Catalunya during the period of study', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Newborns\n* Both sexes\n* Explicit acceptance of the parents or guardians of participation through the signature of the informed consent\n\nExclusion Criteria:\n\n* None'}, 'identificationModule': {'nctId': 'NCT06710366', 'acronym': 'DAO-NEO-2022', 'briefTitle': 'Prevalence of DAO (diamino Oxidase) Deficiency in Newborns', 'organization': {'class': 'INDUSTRY', 'fullName': 'AB Biotek'}, 'officialTitle': 'Prevalence of DAO (diamino Oxidase) Deficiency in Newborns', 'orgStudyIdInfo': {'id': 'DAO-NEO-2022'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Newborns', 'description': 'Newborns born at the centre'}]}, 'contactsLocationsModule': {'locations': [{'zip': '08195', 'city': 'Sant Cugat del Vallès', 'state': 'Barcelona', 'country': 'Spain', 'facility': 'Hospital General de Catalunya', 'geoPoint': {'lat': 41.47063, 'lon': 2.08611}}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL', 'ICF', 'CSR'], 'timeFrame': 'According to legislation', 'ipdSharing': 'YES', 'description': 'AOC1 genetic SNPs prevalence in the studied population'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'AB Biotek', 'class': 'INDUSTRY'}, 'collaborators': [{'name': 'Grupo Hospitalario Quironsalud-Catalunya', 'class': 'UNKNOWN'}, {'name': 'Hospital Universitari General de Catalunya', 'class': 'OTHER'}, {'name': 'Quironsalud', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
