Distribution of potential MAR/SAR sites predicted in the AF9 gene. The AF9 genomic map from nucleotide positions 601–281,480 is illustrated above [EMBL:ENSG00000171843]. The locations of exons 1 to 10 and BamH I (B) restriction sites are shown. Green boxes indicate the two patient BCRs reported in the previous study. These two patient BCRs were denominated as BCR1 and BCR2 [28]. Yellow boxes indicate the two MAR/SARs that were biochemically identified by Strissel and co-workers. These two MAR/SARs were designated as SAR1 and SAR2 [28]. Yellow arrows represent the potential MAR/SAR sites predicted by MRS in our study. Clusters of more than one MRS within close proximity are regarded as a single potential MAR/SAR site. Three MRSs were found in SAR1 (MAR 24-2, 24-3, 24-4). One MRS (MAR 27) has been predicted next to the SAR2. Based on the in silico prediction of MAR/SAR, a SAR region (contains MAR/SAR) and a non-SAR region (does not contain MAR/SAR) were determined to be the regions of study
