Vanishing white matter disease

Introduction

Overview

Vanishing white matter disease is an autosomal recessive, chronic, and progressive leukodystrophy with prominent ataxia and spasticity, cavitary degeneration of the periventricular and subcortical white matter, and exacerbations by infection, head trauma, and other stressors. It is associated with biallelic pathogenic variations in any of the five genes (EIF2B1, EIF2B2, EIF2B3, EIF2B4, and EIF2B5) that encode five subunits of the eukaryotic translation initiation factor 2B (eIF2B). Pathogenic variants in the EIF2B5 gene account for more than half of cases. Patients may develop a wide spectrum of neurologic abnormalities, from prenatal-onset white matter disease to juvenile- or adult-onset ataxia and dementia, sometimes with ovarian insufficiency. The pattern of diffuse white matter abnormalities on brain MRI and diffusion studies is often diagnostic. There is no specific treatment for vanishing white matter disease. Management includes supportive care and avoidance of triggers.

Key points

• Vanishing white matter disease is a chronic progressive leukodystrophy with autosomal recessive inheritance that can present antenatally to later in adulthood.

• Patients with vanishing white matter disease have an unusual susceptibility to mild head trauma, fever, and other stressors.

• The pathognomonic pattern of MRI and diffusion tensor imaging abnormalities are often the earliest clue to diagnosis.

• Pathogenic variants in any of the five genes (EIF2B1, EIF2B2, EIF2B3, EIF2B4, and EIF2B5) that encode subunits of the eukaryotic translation initiation factor 2B (eIF2B) are the cause of vanishing white matter disease and its phenotypic variants.

• There is no cure or specific treatment, and supportive care along with avoidance of triggers is the mainstay of management for vanishing white matter disease.

Historical note and terminology

The earliest literature on vanishing white matter disease was in the 1960s in the form of case reports of patients with chronic progressive gait and motor disturbances whose autopsy showed cystic degeneration of the cerebral white matter surrounded by dense networks of oligodendrocytes (08). Subsequent similar but separate neuropathological case descriptions were reported until the 1980s (58; 17; 02; 16).

Three case series were published in the 1990s. All of them described a childhood-onset, progressive leukoencephalopathy with an autosomal recessive mode of inheritance. Schiffmann and colleagues proposed the term “childhood ataxia with central nervous system hypomyelination” (36). Hanefeld and coworkers identified minor head trauma as a provoking factor (19). They also described the unique proton magnetic resonance spectroscopy findings of the disappearance of all white matter signals and replacement with resonances representing lactate and glucose. In late 1990s, Van der Knaap and colleagues described another series of patients and recognized both febrile infections and minor head trauma as provoking factors for the disease (43; 46). They observed that MRI and magnetic resonance spectroscopy findings were indicative of a progressive form of cystic degeneration of the white matter rather than hypomyelination. This interpretation was substantiated by autopsy findings, and the same group proposed the name “vanishing white matter.”
