(C) The average within-individual correlation (r) between DNA methylation and gene expression (GE) is 2.44 times as large after infection (r=–0.261 ± 0.006) than at baseline (r=–0.106 ± 0.008) in IFNA-specific mSTARR-seq enhancers (right panel), but much less affected by infection at mSTARR-seq enhancers that are shared across conditions (left panel). The gene discussed is IFNA2; the disease is infection.
