Genomic organization of ABCC6P1 and ABCC6P2 , two transcribed pseudogenes of ABCC6. The pseudogenes ABCC6P1 and ABCC6P2 flank their parental gene ABCC6 at a distance of 2.3 Mb and 1.3 Mb, respectively, on chromosome 16p13. Arrows indicate the direction of transcription. The structures of the ABCC6P1 and ABCC6P2 genes and their transcripts are illustrated in higher magnification. Exons are represented by black boxes and numbered in 5' to 3' order. Similarities (%) of pseudogene exons with their corresponding ABCC6 exons are shown in parenthesis. The terminal non-homologous exon of ABCC6P1 is shaded blue. The red box highlights the last exon of ABCC6P2 which contains a part of intron 2. Metric scale bars are indicated for orientation.
