Fig. 1From: Self-reported prenatal tobacco smoke exposure, AXL gene-body methylation, and childhood asthma phenotypesGenomic locations of AXL CpG sites under investigation. CpG sites captured by the same primer set are labeled in the same color to show categorization of the CpG sites into 6 regions. CpG 25 was previously reported to associate with prenatal tobacco smoke exposure (reference #10). CpGs 23, 9, 112, 161 and 754 were previously studied in relation to childhood asthma and related symptoms (reference #19)Back to article page
