Our sample size had sufficient power (>80%) to detect variants previously reported in PD and DLB at the GWAS significance level, namely, MAPT (rs62053943), LRRK2 (rs34637584), BIN1 (rs6733839) and APOE (rs769449)8,14, yet there was no association. This evidence concerns the gene LRRK2 and Lewy body dementia.
