To test for enrichment of genetic variants associated with DNA methylation in the developing brain within fetal brain eQTL, we used a DNA methylation QTL (mQTL) dataset that we published previously using an overlapping set of fetal brain samples [10]. All FDR < 0.05 eQTLs were used to define an annotation category. Enrichment was tested using the set of mQTL that we previously identified at a Bonferroni-corrected threshold P < 3.69 × 10− 13.
