“…These SNPs were pre-selected by avoiding physical proximity in the human genome. We assessed compatibility for multiplex polymerase chain reaction (PCR) amplification using the Muplex resource (Rachlin et al, 2005), which is a convenient webenabled system that, starting from a set of targeted sequences, automatically designs sub-sets of primers that will likely co-amplify in multiplex PCR assays under a number of conditions imposed by the investigator. After applying these criteria, we selected the following two SNP panels to be tested experimentally: AFR (Africans) (rs2697520, rs8035530, rs1372115, rs2789823, rs241679, rs7512316, rs9626698, rs1443985, rs6046024, rs735480) and AMR (Native Americans) (rs8058694, rs691968, rs2234636, rs3760657, rs2619681, rs2569190, rs800292, rs2518967, rs2088102, rs700518).…”
