RBFOX3 and attention deficit-hyperactivity disorder: Moreover, SNP heritability for schizophrenia, bipolar disorder, and major depressive disorder was enriched at Bonferroni-corrected significance in NeuN+ OCRs overlapping either fetal H3K4me1 sites (Figure 5) or H3K4me3 sites, with nominally significant enrichments observed for ASD in NeuN+ OCRs overlapping H3K4me1 sites and for ADHD in NeuN+ OCRs overlapping H3K4me3 sites (Table S3).
