چکیده

A 46-year-old female presented progressive hand tremor at age of 8, associated to cognitive and motor deterioration. She developed incapacitating head tremor and was wheelchair-bound 12 years after onset. Premature ovarian failure (POF) occurred at 27-year-old. In the last 3 years, head tremor became less intense, but she remained with horizontal bidireccional nistagmus. Vanishing white matter disease (VWMD) is an autosomal recessive disorder characterized by cerebellar ataxia, spasticity, and cognitive impairment. Brain MRI discloses symmetric and diffuse white matter lesions ( figure). VWMD manifests from infancy to adulthood; in female, POF may occur. It is caused by mutations in both alleles of one of five genes coding for subunits of eukaryotic translation initiation factor 2B.

Vanishing white matter in Saudi Arabia.

Vanishing white matter disease (VWMD) is an under-diagnosed condition that affects the brains white matter at all ages, especially in the pediatric age group. It belongs to a clinically and genetically heterogeneous group of disorders, collectively known as eukaryotic initiation factor 2B-related disorders. The disorder has been described in different ethnic groups. Here, we describe a case of ...

Impaired eukaryotic translation initiation factor 2B activity specifically in oligodendrocytes reproduces the pathology of vanishing white matter disease in mice.

Vanishing white matter disease (VWMD) is an inherited autosomal-recessive hypomyelinating disease caused by mutations in eukaryotic translation initiation factor 2B (eIF2B). eIF2B mutations predominantly affect the brain white matter, and the characteristic features of VWMD pathology include myelin loss and foamy oligodendrocytes. Activation of pancreatic endoplasmic reticulum kinase (PERK) has...

Brain magnetic resonance imaging helps to differentiate atypical multiple sclerosis with cavitary lesions and vanishing white matter disease.

BACKGROUND AND PURPOSE Multiple sclerosis (MS) patients can present with atypical cavitary lesions mimicking vanishing white matter disease (VWMD). Our objective was to identify brain magnetic resonance imaging (MRI) findings that differentiate these two disorders. METHODS A cross-sectional study was performed including 14 patients with MS with cavitary lesions and 14 patients with VWMD. Two ...

Screening for known mutations in EIF2B genes in a large panel of patients with premature ovarian failure

BACKGROUND: Premature Ovarian Failure (POF), defined as the development of hypergonadotropic amenorrhea before the age of 40 years, occurs in about 1% of all women. Other than karyotype abnormalities, very few genes are known to be associated with this ovarian dysfunction. Recently, in seven patients who presented with POF and white matter abnormalities on MRI (ovarioleukodystrophy) eight mutat...

The small molecule ISRIB rescues the stability and activity of Vanishing White Matter Disease eIF2B mutant complexes

eIF2B is a dedicated guanine nucleotide exchange factor for eIF2, the GTPase that is essential to initiate mRNA translation. The integrated stress response (ISR) signaling pathway inhibits eIF2B activity, attenuates global protein synthesis and upregulates a set of stress-response proteins. Partial loss-of-function mutations in eIF2B cause a neurodegenerative disorder called Vanishing White Mat...
