Genomic organization of the locus encompassinghepcidinandUsf2genes. The genomic organization was determined according to the sequences of the RP23-22G9 clone (A) and the WGS Mm7 supercontig (B) on chromosome 7. The GenBank accession numbers are AC087143 and NW_000310 for panels A and B, respectively. The genes are represented by rectangles (the numbering of the exons is indicated), while the lines correspond to intergenic regions. The arrows represent the direction of transcription. Our analysis (data not shown) confirms genomic organization as represented in panel B.
