PFAS and Alzheimer disease: This number is significantly higher than it would be expected by chance (p < 10−4; S5 Fig), indicating that NETPAGE-selected genes in ADSP are overrepresented in the neighbourhood of PFAS. As common variants identified through GWAS are often tagging loci harbouring rare variants, S1 Table lists selection probabilities for the 21 genes reported in a recent large scale GWAS for AD [24].
