Adeline Vanderver, MD

Dr. Adeline Vanderver is the Director of the Myelin Disorders Program at Children’s National Health System. Dr. Vanderver is an international leader in the study of leukodystrophies, conditions that affect about one in 7,000 children.

Dr. Vanderver has been interested in solving the mysteries of inherited myelin disorders since she was a medical student. She was touched by families that had been trying for years to understand the medical condition their children were experiencing before receiving a diagnosis. Dr. Vanderver also is deeply involved in searching for genetic pathways that might explain how these conditions occur. Just as important, she says, is building community support for patients and their families.

Keith Van Haren, MD


Dr. Van Haren is a clinically trained child neurologist and scientifically trained neuroimmunologist who has been dedicated to the study of myelin disorders for over a decade. After completing his medical training in 2010 and post-doc in 2013, Dr Van Haren helped establish the first US-based consortia for inherited myelin disorders (ALD Connect and GLIA). In 2014, Dr. Van Haren led the effort to establish the first formal care guidelines for inherited myelin disorders. He is currently engaged in an early stage clinical study of vitamin D in X-linked adrenoleukodystrophy.
 
Dr. Van Haren currently oversees a clinical and translational neuroscience program at Stanford University that is dedicated to improving the standard of care for children and adults affected by myelin disorders.

Ernst Wolvetang, PhD

Professor Wolvetang obtained his PhD from the University of Amsterdam. After investigating the role of chromosome 21 transcription factors in Down syndrome during his post-doctoral studies he joined the laboratory of Prof. Martin Pera to help pioneer human embryonic stem cell research. In 2009 He took up a group leader position at the Australian Institute for Bioengineering and Nanotechnology at the University of Queensland to interface with emerging microfluidic, nano- and “smart” surface-technologies at the Institute. His laboratory employs iPSC as in vitro disease models and uses CRISPR genome editing tools to interrogate the underlying gene regulatory networks and epigenetic bases of in particular complex neurological diseases. He leads “Cell reprogramming Australia”, was awarded the 2014 LSQ regenerative medicine prize and is a principal investigator in the ARC Centre of Excellence “Stem Cells Australia”.

The Wolvetang laboratory is currently focused on modelling tRNA synthetase deficiencies and other poorly understood childhood leukoencephalopathies. Our strategy involves generation of induced pluripotent stem cells from patients, correcting or introducing patient mutations with CRISPR, differentiating these into neuronal cell types that inform on pathogenic mechanisms in 2D and 3D (organoid) culture formats, and then subject such brain cell types to deep transcriptomic and proteomic analyses. Using this information and the patient derived cell types we can then next test precision medicine therapeutics. We are very interested in working with clinicians and patient advocacy groups to thus close the circle from bedside to bench and back again.  


Lawrence Wrabetz, MD

Dr. Lawrence Wrabetz currently serves as the Distinguished Professor of Neurology and Biochemistry, as well as the Director of the Hunter James Kelly Research Institute at the University of Buffalo School of Medicine.

He is Associate Editor of the Journal of Neuroscience and of ASN Neuro, a peer-reviewed open access scientific journal covering neurochemistry.

The Wrabetz laboratory is interested in the molecular genetics of myelination, studied primarily in transgenic mice.  Most recently they have focused on the pathogenesis of inherited demyelinating neuropathies or leukodystrophies. Studies in multiple authentic mouse models of Charcot Marie Tooth neuropathies, or Globoid or Metachromatic leukodystrophies have revealed the mechanisms of disease, potential avenues of therapy and the opportunity to test resulting medicines in preclinical trials.

His team was responsible for design and implementation of PRO-ACT project that created the largest clinical dataset in ALS (10,700+ subjects) and is the de-facto reference dataset in ALS research. This platform was selected as the Best Bio-IT project of 2013 by the Bio-IT World Congress. Alex served on the NINDS Common Data Elements committee, is the Chair of the NeuroBANK™ committee of NEALS and is a Board Member of the ALS Research Group (ALSRG) and ALD Connect consortium. Mr. Sherman holds Masters of Science degree in Nuclear Engineering and graduated from a doctorate program in Nuclear Engineering. He is a Principal Associate in Neurology at Harvard Medical School.

Alex's interests and passion are in developing collaborations in clinical research and building disease-specific research networks and consortia to achieve “Big Data” in rare diseases. He is a frequent speaker at academic and industry conferences and has many publications on the topics of collaboration in clinical research, data and biospecimen sharing and technology utilization for these purposes.

Omar Sherbini, MPH (Clinical Research Coordinator)

Omar Sherbini is one of the newest members of the Global Leukodystrophy Initiative, having joined Dr. Vanderver's team at Children's National in August 2015 as a clinical research coordinator. Aside from his clinical/research responsibilities, Omar manages GLIA's day-to-day activities, which may include:

  • Serving as a liaison between GLIA's clinicians and researchers during research initiatives;
  • Engaging with patient advocacy groups and, oftentimes, patient families directly to get them involved in GLIA's strategic planning;
  • Event planning, including the organization of annual scientific and family conferences for GLIA members;
  • Community outreach and PR.

Before joining the GLIA team, Omar obtained a Master of Public Health (MPH) degree from Johns Hopkins, with a focus on infectious diseases. He previously worked in a research laboratory - also at Johns Hopkins - where he investigated stroke pathophysiology and preventative therapies using live animal models.
