Defining Clinical Endpoints in LGMD (GRASP-01-001)
The purpose of this study to learn more about Limb Girdle Muscular Dystrophy by measuring how muscles change over a twelve-month period. Our clinical evaluator will test muscle strength and participants will be asked to complete a series of questionnaires to find out how Limb Girdle impacts daily activities. This information will help plan future studies and drug development for people with LGMD.
• 4 to 65 years of age
• diagnosis of Muscular Dystrophy with weakness in either a limb-girdle pattern, or in a arm or leg
• confirmed mutation in ANO5, CAPN3, DYSF, DNAJB6 or SGCA-G.
• bleeding disorder, platelet count less than 50,000, or currently taking an anticoagulant.
• women who are pregnant
• other illness that would interfere clinical trial (study staff will review)
Natural History Study for DNA Repair Disorders
This research is being done to help us better understand the different DNA repair disorders. We will collect data and samples that we will use to develop new therapies and medicine to help treat the disease. We expect that participants will be in this research study for 3 years. Visits will occur every six months and alternate between in-person and remote. Remote visits should be expected to last 1-2 hours, and in-person visits should be expected to last 3-4 hours.
• at least 6 months old
• diagnosis of Cockayne syndrome (CS), xeroderma pigmentosum (XP), or trichothiodystrophy (TTD), based on genetic testing and/or key clinical characteristics
• have one or more of the neurodevelopmental or neurological complications such as gross motor delay, language delay, altered muscle tone (study staff will review)
• family member of an individual with the above condition
• prior history of systemic gene or cell-based therapy
• participation in a clinical trial for treatment
Determinants of Renal Structural Responses to Enzyme Replacement Therapy (ERT) in Fabry Disease Study (LDN6702)
The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.
• diagnosed with Fabry disease and a clinical decision has been made to obtain a kidney biopsy, a GFR, and urinary albumin studies
• have previously completed clinical trials which included measures of renal function and renal biopsies
• serum creatinine more than 2.5 mg/dL
• known to have a renal disease other than Fabry
Minnesota Neurogenetics Repository
This research study is for participants who have an inherited neuromuscular disorder or neurogenetic disorder, or family members who are unaffected by such disorders
• individuals with DNA repair disorders including Cockayne syndrome, trichothiodystrophy, and xeroderma pigmentosum
• family members with a genetic neurological or muscle disease
• none
Improving Diagnosis and Treatment in Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)
This is a multi-center, prospective, observational cohort registry study looking at kids and their relatives with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT).
• anyone diagnosed with CPVT before 19 years of age.
• significant medical history that isn't related to CPVT
Longitudinal Study of Porphyrias
The objective is to conduct a longitudinal investigation of the natural history, complications, and therapeutic outcomes in people with acute and cutaneous porphyria.
• patient of any age
• diagnosis of a porphyria
• biochemical findings, as documented by laboratory reports of porphyria-specific testing performed after 1980
• elevations of porphyrins in urine, plasma or erythrocytes due to other diseases
Synergistic Enteral Regimen for Treatment of the Gangliosidoses (SYNER-G) (Syner-G)
The Syner-G regimen research study seeks to evaluate the use of a combination of a medication called miglustat and a ketogenic diet for treatment of the gangliosidoses to learn if this combination will provide improved clinical outcomes compared to what we currently know about the natural course of the disease.
• no more than 17 years old
• documented infantile or juvenile gangliosidosis disease
• severe kidney disease
• females who are pregnant or breast feeding
• females who are post puberty who are unwilling to use highly effective birth control
A Natural History Study of the Gangliosidoses
This is a research study documenting the natural history of disease in patients with GM1 or GM2 gangliosidosis. The information collected will be a way to evaluate disease progression and create a disease stage and severity index. Our goal is to use the data collected to measure the effectiveness of any treatments that are developed in the future.
• documented gangliosidosis disease
• able to complete neuropsychological and neurobehavioral assessments
• Late-onset gangliosidosis subjects must be able to tolerate MRI of the head
• none
