LRRK2 and Lewy body dementia: Despite the inclusion of PD patients with probable RBD in the current meta-analysis, notable PD and DLB GWAS loci are absent, including LRRK2, MAPT, BIN1, and APOE. Our sample size is comparable to PD35 and DLB8 GWAS that detected these signals (cases = 1713 & 2981, controls = 3978 & 4391, respectively).
