From: The polymorphic nature of the human dopamine D4 receptor gene: A comparative analysis of known variants and a novel 27 bp deletion in the promoter region

Figure 4

Location of the 27 bp deletion and other polymorphic sites in the promoter region of the human DRD4 gene. The deleted region starts 524 bp upstream of the initiation codon. Figure is drawn to scale and each position is shown relative to the first nucleotide of the initiation codon indicated as +1. A cell type-specific promoter region between -591 and -123 contains the promoter of the gene, and the negative modulator is between the -770 and -679 positions (grey boxes). Open boxes indicate length variants at the DRD4 promoter region. Arrowheads specify the positions of SNPs.
