The detection of two potential breakpoints by agarose gel electrophoresis. PCR amplification was performed on genomic DNA from a normal individual (Normal) and two unrelated individuals with tri-allelic pattern at TPOX undergoing WGS analysis (Sample1 and Sample2), respectively, using indicated primer set. PCR products were subjected to agarose gel electrophoresis. A DNA ladder was used as the marker (TIF 393 kb)
