Participants will be re-evaluated on an annual basis.", "detailedDescription"=>"There is a vast spectrum of clinical manifestations encountered in individuals with lysosomal storage diseases. Lysosomal storage disorders occur when an enzyme necessary for breaking down intracellular fats, proteins, recycled products and organelles in the cell is deficient. As a result, substrate accumulates within the lysosomes affecting different organ systems. The most common lysosomal storage disease, Gaucher disease (GD), results from the inherited deficiency of the enzyme glucocerebrosidase, which breaks down the lipid glucocerebroside. The disease is characterized by extremely variable manifestations, with some patients presenting in childhood with hepatosplenomegaly, anemia, thrombocytopenia and bony problems, some in infancy with a lethal neurodegenerative course, while others remain asymptomatic into their eighth decade. GD has traditionally been divided into three clinical subtypes, type 1 (non-neuronopathic), type 2 (acute neuronopathic), and type 3 (chronic neuronopathic) delineated by the absence or presence of neurologic involvement and its rate of progression. Some patients, however, defy classification into these three categories, and it may be more accurate to regard GD as a continuum of phenotypes. In addition, patients and carriers of mutations in GBA1, the gene for GD, are at increased risk for developing Parkinson disease (PD) and related neurodegenerative disorders.\n\nThis is a longitudinal natural history study of patients with lysosomal storage disorders with emphasis on phenotypic heterogeneity of GD and those at risk for the development of parkinsonism. Our goal is to identify genetic, biochemical, and clinical parameters that are associated with disease severity in individuals with lysosomal storage disorders to identify individuals with milder or early phenotypic manifestations, and to explore the natural history and extent of associated clinical manifestations. We also study subjects with GBA1 mutations who are at higher risk for developing parkinsonism to identify early disease manifestations and potential biomarkers. Participants are evaluated at the NIH to better characterize the clinical, genetic and pathophysiological features of these disorders. In order to better understand the entire effect of the enzyme deficiencies and the function of the specific proteins involved, emphasis is placed on individuals with atypical presentations. In particular, we will focus on subjects with GD and PD, to better understand the association between the two disorders. Following an initial comprehensive workup, participants will be studied either in the inpatient wards or the outpatient clinic and will be re-evaluated at periodic intervals longitudinally."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD", "ADULT", "OLDER_ADULT"], "minimumAge"=>"1 month", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"Patient (or family members of patient) must be found to have or be a carrier of a documented lysosomal storage disorder.@@@", "healthyVolunteers"=>true, "eligibilityCriteria"=>"* INCLUSION/EXCLUSION CRITERIA:\n\nFor inclusion, the participant, of any age after birth, on initial screening must be found to have or be a carrier of a documented lysosomal storage disorder or be a family member of a documented proband. Healthy controls, \\> 18 years of age, will be recruited through the NIH healthy volunteer pool or we will invite unaffected spouses or relatives to participate. Healthy controls are necessary to determine the frequency of motor and non-motor symptoms in the general population. Parkinson disease patients, \\> 18 years of age, will be recruited from the Parkinson disease clinic at the NIH or by self-referral and will also be used for phenotypic comparison with GBA1-associated parkinsonism.\n\nIndividuals who, in the opinion of the Investigator, are unable to comply with the protocol or have medical or social conditions that would potentially increase the risk of participation will be excluded from enrolling in the study. There will be no exclusion based upon age, gender, ethnicity, socioeconomic status, or any other factor. Cognitively impaired individuals may be enrolled if the legal guardian or durable power of attorney (DPA) consents, and assent will be obtained, when appropriate because a significant portion of patients with neurodegenerative disorders may develop cognitive impairment and it is important to include this information in the clinical phenotype. Pregnant or nursing women will also be included because all evaluations and procedures in this protocol do not pose risk to the mother and the fetus as no radiation or imaging studies will be performed for research purpose. Pregnancy in patients with GD and other lysosomal storage disorders presents specific challenges with regards to skeletal, hematological, and possibly visceral complications throughout gestation. It is important to capture the natural history of the disease during pregnancy to assess benefits of initiation/continuation/discontinuation of therapy depending on clinical signs and symptoms. Information obtained from participation of this population is of great value for counseling, prevention of complications, and prognostic implications. Participants are free to refuse any evaluation without affecting participation in this protocol.\n\nThese are generally pan-ethnic disorders. Efforts will be made to include any patient from an under-represented minority with these disorders.\n\nFamily members eligible/recruited include adult obligate carrier relatives, parents and siblings of Gaucher disease probands, and/or any relative with and without parkinsonism, where noncarriers volunteer for participation to serve as controls.\n\nEligibility criteria for healthy and PD control group participants include healthy participants recruited from the Healthy volunteers office or healthy non-mutation carriers family members who voluntarily agree to participate. Patients with Parkinson disease who do not carry GBA1 mutations are eligible to participate to serve as controls"}, "identificationModule"=>{"nctId"=>"NCT00001215", "briefTitle"=>"Genetic Studies of Lysosomal Storage Disorders", "organization"=>{"class"=>"NIH", "fullName"=>"National Institutes of Health Clinical Center (CC)"}, "officialTitle"=>"Studies of Genetic Heterogeneity in Patients With Lysosomal Storage Disorders", "orgStudyIdInfo"=>{"id"=>"860096"}, "secondaryIdInfos"=>[{"id"=>"86-HG-0096"}]}, "armsInterventionsModule"=>{"armGroups"=>[{"label"=>"Control", "description"=>"healthy volunteers"}, {"label"=>"Family Member", "description"=>"a family member of a documented proband"}, {"label"=>"Patient", "description"=>"the participant on initial screening must be found to have or be a carrier of a documented lysosomal storage disorder"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"20892", "city"=>"Bethesda", "state"=>"Maryland", "country"=>"United States", "facility"=>"National Institutes of Health Clinical Center", "geoPoint"=>{"lat"=>38.98067, "lon"=>-77.10026}}], "overallOfficials"=>[{"name"=>"Ellen Sidransky, M.D.", "role"=>"PRINCIPAL_INVESTIGATOR", "affiliation"=>"National Human Genome Research Institute (NHGRI)"}]}, "ipdSharingStatementModule"=>{"infoTypes"=>["STUDY_PROTOCOL"], "timeFrame"=>"pending", "ipdSharing"=>"YES", "description"=>"pending", "accessCriteria"=>"pending"}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Human Genome Research Institute (NHGRI)", "class"=>"NIH"}, "responsibleParty"=>{"type"=>"SPONSOR"}}}}
