GBA mutation frequencies by group^a

Abbreviations: AD = dementia with high-level Alzheimer disease neuropathologic changes without Lewy body disease neuropathologic changes; LBD-AD = dementia with Lewy body disease neuropathologic changes and high-level Alzheimer disease neuropathologic changes; pDLB = pure dementia with Lewy bodies (dementia with Lewy body disease neuropathologic changes and no or low-level Alzheimer disease neuropathologic changes).

^a The number of mutation carriers is given relative to all subjects in the group, followed by the percentage of mutation carriers within the group.
