highly significantP < 2.2x10 -16
DNA methylation at 84.7% of these sites was significantly associated with at least one common genetic variant using a stringent mQTL threshold (P < 1x10 -8 ) ( S2 Table ); this represented a highly significant enrichment for mQTL effects (P < 2.2x10 -16 ) compared to less-heritable DNA methylation sites (defined as those with A < 0.8), amongst which only 24.5% were associated with a mQTL variant.
