It has been proposed that there is an increased frequency of glucosidase-β mutations in Lewy body disorders. Our comprehensive DNA sequencing approach found a small number of glucosidase-β mutations in 101 neuropathologically defined Lewy body disease cases (3%) compared to 99 healthy post-mortem controls (1%); odds ratio 3.0 (95% CI: 0.3-29, p = 0.3). All three affected carriers were classified as diffuse Lewy body disease (n = 3/50; 6%). Our study suggests glucosidase-β variants have a limited role in susceptibility to Lewy body disease in North America.
