SCZ TWAS genes at a glance

Manhattan plot of SCZ TWAS associations from each expression reference panel. Each point represents an individual gene with physical position on the x-axis and (signed) Z-score for association on the y-axis.

SCZ & chromatin associations in detail

All transcriptome-wide significant TWAS associations and any corresponding chromatin associations.

Study: Expression reference panel used for TWAS (CMC/brain; NTR/blood; YFS/blood; MET/adipose). Z: Z-score for TWAS association, positive sign means increased expression leads to increased risk. INFO: Expected TWAS prediction R2. GWAS P: P-value of the best GWAS SNP in the 1MB locus. joint: Whether this gene was significant in a joint model using all genes (across all expression panels). chromatin: Chromatin TWAS associations (if any). Note: Use search bar to filter chromatin phenotypes (H3k27ac, H3k4me1, H3k4me3, DHS, RPB2, PU1) or reference panels.
