The AF9 SAR region is from coordinates 236,059 to 246,292 [Ensembl:ENSG00000171843]. The name, class, nucleotide position and length of the predicted repeat elements are shown. The region amplified by the reverse primer (AF9 236,211 R) is from coordinates 236,059 to 236,211 while the region amplified by the forward primer (AF9 245,507 F) is from coordinates 245,507 to 246,292. The amplified SAR region contains one repeat element, namely ERE2_EH (at coordinates 245,627–245,728)
