Genomic fine-mapping of the TPCN1 locus
(A) Scatterplot showing the beta regression coefficients of common variants (MAF ≥ 1%) at the TPCN1 locus in the Chia et al. LBD GWAS (y axis)12 and Bellenguez et al. Alzheimer’s disease GWAS (x axis).22
(B) Beta-beta plot comparing the TPCN1 locus variants in the Chia et al. LBD GWAS (y axis)12 with the Nalls et al. Parkinson’s disease GWAS results (excluding 23&Me data; x axis).23
(C) Single-nucleus RNA sequence analysis of the TPCN1 deletion-tagging SNP rs6489896 identified a significant cis-eQTL for RITA1 in excitatory neurons.
