Welcome to the Brain xQTL Serve

This is a resource for assessing the impact of genetic variation on multiple types of molecular traits derived from the human brain cortex:

xQTL pipeline

*co-senior authors


Lists of significant and genome-wide associations, results of mediation analysis and cell-specificity test, as well as code for x-QTL-weighted GWAS are available:

Explore associations between SNPs and molecular traits in your browser!

You can qeury our data in two ways: by providing a (i) SNP rsID, or a (ii) gene symbol.
