Fig. 3From: Methylation of serotonin regulating genes in cord blood cells: association with maternal metabolic parameters and correlation with methylation in peripheral blood cells during childhood and adolescenceMethylation in cord blood cells, mapped to respective genomic regions in A. serotonin transporter (SLC6A4) and B. serotonin receptor type 2A (HTR2A) genes. Rectangles in gene scheme denote exons, horizontal solid lines denote introns, and dashed horizontal lines denote intergenic regions (GRCh38.p14/hg38). Methylation levels in ARIES cohort (n = 808) are shown above the gene scheme and in PlaNS cohort (n = 203) below the gene scheme, with CpG sites analyzed in both cohorts highlighted in red and blue. CpG sites in PlaNS cohort are numbered as in Fig. 1 and Additional file 1: Table S2Back to article page
