Schematic representation of human ALDH1L1 gene locus (A) and the CpG island in the promoter region (B). Double-headed arrows indicate location of PCR primers (C) for bisulfite genomic sequencing. CpG sites and their genomic positions within the CpG island (–525 to +918) are represented by vertical lines. Nucleotide positions are numbered relative to the transcriptional start site.
