Abstract: | GBA variations are common risk factors for Parkinson's disease (PD), and are found in 21.7% of Ashkenazi PD patients (AJ-PD), 4.23% of them carry an allele, 370Rec, which is different from the common GBA-N370S allele. Using whole-genome-sequencing of 370Rec carriers, N370S carriers, and non-carriers, we characterize the unique 370Rec haplotype in AJ-PDs, and show that it harbors a missense variant replacing the highly conserved methionine-27 with valine in the transmembrane domain of the mitochondrial SLC25A44. |
