Fig. 1From: 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 adolescenceGenomic regions analyzed in the PlaNS cohort. Shown are the structures of genes encoding A. serotonin transporter (SLC6A4), B. monoamine oxidase A (MAOA), and C. serotonin receptor type 2A (HTR2A), along with the targeted sequences (5′–3′), starting at Chr17:30,235,549, Chr23:43,656,341, and Chr13:46,897,546, respectively (according to GRCh38.p14/hg38 assembly). Black rectangles denote exons and horizontal solid lines denote introns. The analyzed CpG sites are underlined and in bold; details of their genomic positions are provided in Additional file 1: Table S2. CpG sites covered by the Illumina Infinium Human Methylation 450K BeadChip and, therefore, available also in the ARIES database, are indicated by red rectanglesBack to article page
