CI = confidence interval; GWAS = genome-wide association study; LBD = Lewy body dementia; MSA = multiple system atrophy; OR = odds ratio; PD = Parkinson’s disease; RBD = REM sleep behaviour disorder.

a

Uncorrected P-value, all results were not significant after correction for multiple comparisons.

b

p.N352S was found in imputed genotyping files with an R2 value of 0.975 for dementia with Lewy bodies GWAS, 0.953 for multiple system atrophy GWAS, 0.997 for RBD GWAS, and >0.96 for Parkinson’s disease GWAS.

c

Including proxy cases.

d

Frequency estimates were based on a subset of the data including 21 478 cases and 24 388 controls.
