Recent large-scale genetic analyses such as genome-wide association study (GWAS) and whole-genome sequencing analysis identified the APOE, BIN1, and TREM175 loci in addition to the GBA1 and SNCA loci for DLB susceptibility (Bras et al. 2014; Bracaglia., et al. 2018; Chia et al. 2021). This evidence concerns the gene GBA1 and Lewy body dementia.
