About the Vanishing
White Matter Consortium

Since the first identification of Vanishing White Matter (VWM) based on clinical profile and MRI pattern, a tremendous amount of research investigated the molecular cause, biological processes, and clinical aspects of the disease. Not only were the underlying genetic mutations identified, but both preclinical and clinical studies also generated an increased understanding of the disease.

With the improved insights, worldwide efforts now focus on treatment opportunities for VWM, which are in different stages of development. Considering the low prevalence and the high variation in age of onset and disease course of VWM, clinical trial design for VWM faces several challenges. The need for an unbiased group of academic medical experts to assist in the drug development processes and clinical trial design became evident. For this purpose, the VWM Consortium has been established, consisting of 9 (pediatric) neurologists from 8 academic medical centers worldwide, all involved in leukodystrophy patient care and research.

Mission statement

The mission of our consortium is to enable and accelerate therapeutics for Vanishing White Matter, aiming at accessibility and affordability for all patients. To this purpose, our international collaboration engages partners to provide unbiased analyses of different therapeutics, using smart trial design to address recruitment challenges, and promotes efficient and effective use of therapeutics in this rare disease.

The VWM Consortium receives input from independent experts, works closely together with the Industry Alliance Office of Amsterdam Neuroscience, and engages with international biotechnology and pharmaceutical industry, and patient and family organizations.

Consortium Members

Prof. Marjo van der Knaap
Amsterdam UMC, the Netherlands

Marjo van der Knaap is an adult and pediatric neurologist, employed at Amsterdam UMC since 1991. She is head of pediatric neurology. In 2000 she founded the Amsterdam Leukodystrophy Center, where patient care is combined with fundamental, translational, and clinical research. She contributed to the MRI definition of VWM. In 2001/2002 her group discovered 5 VWM-related genes. Her research contributed to insight into VWM pathophysiology and therapy targets. She initiated the first therapy trial in VWM.
