In a GWAS of 1743 DLB patients, of whom 1324 were autopsy-confirmed [11], no associations were identified at the PLCG2 or ABI3 loci, although significant associations were reported for APOE, SNCA and GBA. More recently, whole exome sequencing of 1118 autopsy-confirmed DLB patients [19] did not identify significant association with PLCG2_rs72824905-G. This evidence concerns the gene APOE and Lewy body dementia.
