|a Objective: To summarize the clinical features of leukoencephalopathy with vanishing white matter disease (VWM) in children. Methods: A retrospective cohort study was performed on 54 genetically diagnosed VWM patients in Peking University First Hospital from January 2007 to March 2019. Paper registration form and electronic medical record system were used to collect the data,and the children were divided into five groups according to the age of disease onset:<1 year, 1-<2 years, 2-<4 years, 4-<8 years and 8-<18 years respectively. The progression of motor function, episodic aggravation, epileptic seizures, survival time, brain magnetic resonance imaging (MRI) and genotype features were analyzed and compared. Non-parametric test, χ(2) test or Fisher's exact test were used for comparison among groups; Kaplan-Meier survival curve was adopted to delineate the survival status of the children. Results: Fifty-four VWM patients were included in the study, including 34 males and 20 females.The age of disease onset was 2 years and 8 months (ranged from 6 months to 9 years and 7 months). Onset age was less than 1 year in 5 cases; onset age was 1-<2 years in 12 cases; onset age was 2-<4 years in 25 cases; onset age was 4-<8 years, in 10 cases; onset age was 8-<18 years in 2 cases; 94% (51/54) of patients had complaint of motor regression at the first visit; 87% (47/54) of patients suffered from episodic aggravation. Episodic seizures occurred in 43% (23/54) patients. In survivors with disease durations of 1-3 years, in 38% (9/24) patients the disease was classified as grades Ⅳ-Ⅴ by gross motor function classification system (GMFCS). For the onset age 1-<2 years group, 1 patient was classified as GMFCS Ⅳ among 3 survivors with disease durations of 1-3 years. As for the 2-<4 years group, 6 patients were classified as GMFCS Ⅳ-Ⅴ among 15 patients with disease durations of 1-3 years, whereas 1 patient was classified as GMFCS Ⅳ-Ⅴ among 4 patients with disease durations of 1-3 years in the 4-<8 years group. Lesions, liquefaction and diffusion restriction in brain MRI were compared among different groups, and it was revealed that the earlier the age of disease onset was, the more likely the subcortical white matter (frontal lobe P<0.01,temporal and parieto-occipital lobe both P=0.002), internal capsule (anterior limb P<0.01, posterior limb P=0.00) and brain stem (midbrain P=0.001, pons P<0.01) were to be involved. In addition, internal capsule (anterior limb P=0.002, posterior limb P=0.005) and brain stem (midbrain P=0.001, pons P=0.003) showed more diffuse restricted diffusion. Moreover, the subcortical white matter (frontal and parieto-occipital lobe both P<0.01, temporal lobe P=0.005) showed earlier rarefaction. The 1-year and 2-year survival rates of the overall patients were 81% and 75% respectively, while the 15-year survival rate was 45%. EIF2B5 gene variation was the most common, which accounts for 43% (23/54), followed by EIF2B3 (22%, 12/54). Conclusions: The majority of VWM patients complained of motor regression at the first visit, episodic aggravation and epileptic seizures are common in the course. Earlier age at onset is associated with more rapid clinical progression, shorter survival time as well as more extensive lesions, liquefaction and diffusion restriction in brain MRI. The most common variant gene is EIF2B5, followed by EIF2B3
