Most recently, in a second genome‐wide association study in DLB including data from 2591 patients and 4027 controls, Chia et al.[62] identified five significant loci: three previously identified (APOE, SNCA, and GBA) and two new loci, one of which had been previously implicated in AD (BIN1)[63] and the other in PD (TMEM175).[64] Again, the authors reported “a notably different profile at the SNCA locus” in DLB and PD, suggesting that “the regulation of SNCA expression may be different” in the two diseases. Here, APOE is linked to Lewy body dementia.
