D409H GBA1 mutation accelerates the progression of pathology in A53T α-synuclein transgenic mouse model
Abstract Heterozygous mutations in glucocerebrosidase 1 (GBA1) are a major genetic risk factor for Parkinson’s disease and Dementia with Lewy bodies. Mutations in GBA1 leads to GBA1 enzyme deficiency, and GBA1-associated parkinsonism has an earlier age of onset and more progressive parkinsonism. To...
