Although SNPs from BIN1 (rs744373) loci may not play a major role in PD, PD dementia (PDD), or PD-mild cognitive impairment in a Chinese population, SNPs from BIN1 (rs6733839) loci was identified in patients with Lewy body diseases (LBDs) in a Caucasian population [33,34]. This evidence concerns the gene BIN1 and Lewy body dementia.
