Although less well-characterized or studied, recent GWAS and whole-genome sequencing efforts in Lewy body dementia (i.e., PDD and DLB) in Caucasian populations have nominated at least five loci, including three that are also risk loci for PD (SNCA, GBA, and TMEM175) and two other (APOE and BIN1) known risk loci for Alzheimer’s disease [91, 92]. Here, TMEM175 is linked to Lewy body dementia.
