摘要: Objective : Glucocerebrosidase gene (GBA) variants that cause Gaucher disease are associated with Parkinson (PD) and dementia Lewy bodies (DLB). To investigate the role of GBA in multiple system atrophy (MSA), we analyzed a large case–control series. Methods We sequenced coding regions flanking splice sites 969 MSA patients (574 Japanese, 223 European, 172 North American) 1509 control subjects (900 315 294 American). focused solely on Gaucher-disease-causing variants. Results In Japanese series, found nine carriers among (1.65%) eight (0.89%). European three (1.35%) two (0.63%). American five (2.91%) one carrier (0.34%). Subjecting each series to Mantel–Haenszel analysis yielded pooled odds ratio (OR) 2.44 (95% confidence interval [CI], 1.14–5.21) P-value 0.029 without evidence significant heterogeneity. Logistic regression similar results, an adjusted OR 2.43 CI 1.15–5.37) 0.022. Subtype showed significantly cerebellar subtype (MSA-C) (P = 7.3 × 10−3). Interpretation The findings indicate that, as PD DLB, MSA.
