Genetic Association Between Alzheimer’s Disease Risk Variant of the PICALM Gene and EEG Functional Connectivity in Non-demented Adults

Abstract: Genome wide association studies (GWAS) have identified and validated the association of the PICALM genotype with Alzheimer's disease (AD). The PICALM rs3851179 A allele is thought to have a protective effect, whereas the G allele appears to confer risk for AD. The influence of the PICALM genotype on brain functional connectivity in non-demented subjects remains largely unknown. We examined the association of the PICALM rs3851179 genotype with the characteristics of lagged linear connectivity (LLC) of resting E… Show more

“…According to the amyloid hypothesis, a wide variety of genes identified are involved in pathological Aβ processing ( Figure 2 and Table 1 ), such as the disintegrin and metalloproteinase domain-containing protein 10 ( ADAM10 ), which is the most important α-secretase in the brain that could cause increases in the Aβ42/Aβ40 ratio [ 33 , 34 , 35 ]. In the same way, the phosphatidylinositol-binding clathrin assembly protein ( PICALM ) initiates the polymerization of clathrin, which contributes to NP formation [ 36 , 37 , 38 ]; clustered mitochondria protein homolog ( CLU ), a chaperone that prevents the aggregation of foreign proteins, has been found to inhibit the formation of amyloid fibrils by APP and other genes involved [ 39 , 40 , 41 ].…”

“…For instance, alterations of brain rhythms and functional connectivity have been revealed in EEG and MEG studies [178][179][180]. Relationships between various AD genetic risk factors and EEG phenotypes have also been reported [181][182][183][184]. Hence, compared with a single omics category, integration of multiomics information allows systemic exploration at multiscale layers to better understand the comprehensive biological information flow that underlies the disease and to pave the way for precision medicine.…”

“…For functional connectivity analysis, we utilized a method that applies a single voxel at the centroid of each BA using eLORETA software [ 109 , 110 , 135 , 136 ]. A connectivity analysis between pairs of 84 ROIs in two EEG frequency bands was conducted for all physical exertion levels using independent sample t-tests that were corrected for multiple comparisons using a nonparametric randomization method based on the “maximal statistic.” The same permutation test was applied with 5,000 randomizations to identify the critical probability thresholds at significant levels and to correct type 1 errors.…”
