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. The gene discussed is LRRK2; the disease is Parkinson disease.
