VISTA plot displaying DTNBP1 gene structure and evolutionary conserved regions in a comparison of human, dog, mouse and opossum DNA sequences. Conserved nongenic region (CNG, in red) is defined as an alignment at least 100-bp long and at least 70% identity. The plot used human gene and annotations as reference. In each gene line, a vertical bar denotes an exon, a dashed line denotes a shorter intronic region and a double forward slash denotes a longer intronic region than the human sequence.
