LeukoSEQ: Whole Genome Sequencing As a First-Line Diagnostic Tool for Leukodystrophies
Description

Leukodystrophies, and other heritable disorders of the white matter of the brain, were previously resistant to genetic characterization, largely due to the extreme genetic heterogeneity of molecular causes. While recent work has demonstrated that whole genome sequencing (WGS), has the potential to dramatically increase diagnostic efficiency, significant questions remain around the impact on downstream clinical management approaches versus standard diagnostic approaches.

COMPLETED
The Nosology and Etiology of Leukodystrophies of Unknown Causes
Description

Background: - A leukodystrophy is a disease affecting the white matter of the brain. The white matter conducts electricity from one part of the brain to the other. If the insulation, or myelin, is damaged, the brain s electrical pathways will not work properly. Researchers are trying to identify what causes leukodystrophy. Objectives: * To collect detailed clinical characterizations, including histories, physical examinations, biochemical tests, genetic studies, and neurophysiologic and neuroimaging studies in patients with unclassified leukodystrophies to comprehensively characterize such patients and obtain comparative clinical profiles. * To collect detailed clinical characterizations, including histories, physical examinations, biochemical tests, genomic and proteomic tissue, and neurophysiologic and neuroimaging studies in patients with known leukodystrophies to investigate the underlying pathogenesis of these disorders. * To better understand leukodystrophies of unknown cause and to identify the part of the DNA of the patient with leukodystrophy that is causing the problem. Eligibility: * Any individual with a known or suspected leukodystrophy is eligible to participate in this protocol, including * Patients with white matter disease that is unclassified or of unknown cause, including but not limited to leukoencephalopathies with calcifications, leukoencephalopathies with cysts, leukoencephalopathies with hypomyelination, and leukoencephalopathies with brainstem involvement. * Parents or siblings of these subjects. * Exclusion criteria include patients too ill to travel to the Clinical Center and patients for whom the leukoencephalopathy is felt to be secondary to an acquired cause (for example, traumatic or infectious). Design: * Patients will be seen either as an inpatient or outpatient depending on the tests that are planned. Patients may need to stay at the Clinical Center for 3 to 5 days. * The following tests will be conducted as part of standard clinical care: * Physical and neurological examinations, including blood and urine tests. * Magnetic resonance based studies to produce a picture of the patient s brain (under general anesthesia). * Spinal tap to measure chemicals in the spinal fluid (under general anesthesia in young children). * Nerve biopsy, if the peripheral nerves are affected, or muscle biopsy, if the cells called the mitochondria or the muscles are involved (both under general anesthesia). * The following studies may be performed as part of participation in the research: * Blood, urine, spinal fluid, or muscle to understand the proteins, DNA, and molecules in these tissues. * Skin biopsy to grow (in culture) skin cells and to analyze the skin microscopically. * DNA studies to find new genes responsible for leukodystrophies and to better understand these diseases. * Participation should be based on an interest to help further the research on leukodystrophies. Specific information about a patient s present or future health risks may not be gained.

COMPLETED
The Classification and Cause of Leukodystrophies of Unknown Cause
Description

Leukodystrophy is a disease of the white matter of the brain. White matter is the portion of the brain responsible for conducting electrical impulses from one area of the brain to the other. Insulating cells called myelin cover the brain and nerve cells in the white matter. If myelin becomes damaged electrical information cannot be transferred properly. Many patients suffering from leukodystrophies do not fit the description of any of the defined types of leukodystrophies and are therefore considered to have a leukodystrophy of unknown cause. The purpose of this study is to define groups of patients with leukodystrophies and to work toward finding the cause of the disorders. In order to do this, researchers will analyze patients with leukodystrophies of unknown causes. Patients will undergo clinical, neurophysiologic, biochemical, and genetic examinations and tests. Researchers believe that by studying these patients and their disorders they will be able to better understand the causes of myelin destruction, and eventually lead to effective treatments for these disorders.

A Study of Intrathecal SHP611 in Children With Metachromatic Leukodystrophy
Description

The main aim of the study is to determine if SHP611 given by injection into the spinal fluid that surrounds the brain and spinal cord (intrathecal; IT) prolongs the time for children with Metachromatic Leukodystrophy (MLD) to retain the ability to move from place to place. Other aims of the study are to determine the effects of intrathecal administration of SHP611 on movement and speech functions and to learn how well SHP611 injected in the spinal fluid that surrounds the brain and spinal cord is tolerated. Study participants will receive SHP611 for about 2 years with the possibility of an extended treatment period.

Aclarubicin for the Treatment of Retinal Vasculopathy With Cerebral Leukodystrophy
Description

The goal of the investigator is to utilize Aclarubicin to treat patients with Retinal Vasculopathy with Cerebral Leukodystrophy (RVCL), a rare and devastating genetic disease with no available specific treatment. RVCL results from a mutation in the tail end of the TREX1 (Three Prime Repair Exonuclease 1) gene, a major deoxyribonucleic acid (DNA) repair enzyme. The RVCL-specific mutations cause expression of a truncated and mislocalized protein. RVCL is an inherited disorder whose symptoms begin at middle age and initially predominantly affects the eye and brain. Because it is an 'autosomal dominant' disease, it strikes both males and females equally. A person with RVCL has a 50-50 chance of transmitting the gene to each child. The investigator's published studies demonstrated in a mouse model for RVCL and in vitro studies with patients' cells that defects were corrected by use of Aclarubicin, an anthracycline antibiotic often used to treat cancer. Thus, there is a strong rationale for conducting a clinical trial of aclarubicin in patients with RVCL. The dosage to be initially administered to RVCL patients initially will be \< 10% of that typically used in cancer therapeutics and will be given monthly on four consecutive days for six months. Patients will undergo assessments every six months to determine disease response. Patients that do not have clear objective response may be dose escalated by 1 dose level with permission of the principal investigator permitting the patient has not previously experienced any toxicities requiring dose modifications. We will evaluate the safety and clinical efficacy of Aclarubicin for the treatment of RVCL and evaluate its effects on cellular function. This work will generate the first clinical research data on the investigational product's utility in treating RVCL. Patients are followed for at least 2 years upon completion of Aclarubicin administration completion. We are not longer administering the drug, but are in the post-drug follow up arm of the study.

The Myelin Disorders Biorepository Project
Description

The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

Early Check: Expanded Screening in Newborns
Description

Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.

COMPLETED
Allogeneic Bone Marrow Transplant for Inherited Metabolic Disorders
Description

Rationale: Chemotherapy administration before a donor stem cell transplant is necessary to stop the patient's immune system from rejecting the donor's stem cells. When healthy stem cells from a donor are infused into the patient, the donor white blood cells can provide the missing enzyme that causes the metabolic disease. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving a monoclonal antibody, alemtuzumab, before transplant and cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. This may be an effective treatment for inherited metabolic disorders. Purpose: The design of this study is to achieve donor cell engraftment in patients with standard-risk inherited metabolic diseases with limited peri-transplant morbidity and mortality. This will be achieved through the administration of the chemotherapy regimen described. The intention is to follow transplanted patient for years after transplant monitoring them for complications of their disease and assisting families with a multifaceted interdisciplinary approach.

HSCT for High Risk Inherited Inborn Errors
Description

Hematopoietic stem cell transplantation has proven effective therapy for individuals with adrenoleukodystrophy (ALD), metachromatic leukodystrophy (MLD) or globoid cell leukodystrophy (GLD, or Krabbe disease). This protocol also considers other inherited metabolic diseases such as, but not limited to, GM1 gangliosidosis, Tay Sachs disease, Sanfilippo syndrome or Sandhoff disease, I-cell disease (mucolipidosis II). For patients with advanced or rapidly progressive disease, the morbidity and mortality with transplantation is unacceptably high. Unfortunately, there are no viable alternative therapeutic options for these patients; if transplantation is not performed the patients are sent home to die. Our group at Minnesota has developed a new protocol incorporating transplantation using a reduced intensity conditioning regimen designed to decrease toxicity associated with the transplant procedure. This regimen will make use of the drug clofarabine, which has lympholytic and immune suppressive properties without the neurologic toxicity observed in the related compound, fludarabine, commonly used for transplantation. In addition, several agents providing anti-oxidant and anti-inflammatory properties will be used to assist in the stabilization of the disease processes. This revised transplant protocol will test the following: 1) the ability to achieve engraftment with the reduced intensity protocol, 2) the mortality associated with transplant by day 100, 3) patient outcomes, based on differential neurologic, neuropsychologic, imaging and biologic evaluations prior to transplantation and at designated points after transplantation (day 100, 6 months, 1, 2 and 5 years). Additional biologic studies will include pharmacokinetics of clofarabine and mycophenolate mofetil (MMF). In addition, for patients undergoing lumbar puncture studies, cerebrospinal fluid (CSF) will be requested for determinations of biologic parameters.
