The proportion of heritability of persistent ADHD attributable to common single-nucleotide polymorphisms on the liability scale (SNP- h 2 ) was 0.19 (SE = 0.024), with a nominally significant enrichment in the heritability of variants located in conserved genomic regions ( P = 5.18E−03) and in the cell-specific histone mark H3K4me1 ( P = 3.17E−02) (Fig.
