Figure Lengend Snippet: Overview of experimental workflow Affinity purification MS were completed on the undifferentiated KOLF2.1J WT cell line. Bulk RNA-seq and ONT long-read WGS + 5 mC methylation analysis was completed on undifferentiated KOLF2.1J clones containing the following rs11610045 genotypes: A|A (WT), G|G (edited), and A|A (reversed). WT and edited (but not reverse edited) clones were differentiated to iPSC-derived cortical neurons and bulk RNA-seq completed. iPSC, induced pluripotent stem cell; sgRNA, single-guide ribonucleic acid; ssODN, single-strand oligodeoxynucleotide; RNP, ribonucleoprotein; HDR enhancer, homology-directed repair enhancer; ONT, Oxford Nanopore Technologies; WGS, whole-genome sequencing.

Figure Lengend Snippet: Restoring the rs11610045 G|G genotype to A|A also restores gene expression for a subset of genes (A) CRISPR-Cas9 editing of the rs11610045 G|G genotype to A|A restored the expression of 75 genes to WT levels. Green bars represent the log2FC when comparing the edited rs11610045 G|G genotype with that of the A|A genotype (WT) KOLF2.1J cells. Blue bars represent the log2FC when comparing gene expression in the rs11610045 A|A (reversed) with that of the rs11610045 G|G genotype (edit) clones. In all instances, log2FC > 1 and Bonferroni adj. p value <0.05. (B) Expression of CEL , PDGFB , and THBS2 are rs11610045 genotype dependent and have been linked to PD. Boxplots show the median (center line), interquartile range (box), and whiskers extending to 1.5× the interquartile range. Individual data points are overlaid. (C) PDGFB interacts with THBS1 in a protein-protein interaction network (StringDB, high confidence interaction score ≥0.700).
