electropherograms
Normal and mutated alleles are identified according to repeat motif shifts. Tetranucleotide markers (D14S588 and D1S551) show the corresponding normal allele, as well as the mutated allele that was shifted greater than 1 or less than 2 repeat motifs. Mutated alleles are indicated with a red star and the number of repeat motif shifts is in parentheses. (-) indicated a loss of repeat units, while (+) indicated a gain of repeat units. Normal alleles are shown next to their mutated alleles. Each set of peaks is identified by the marker name and repeat motif (top row). Shown below each peak is the size of each allele in base pair (bp). Markers were labeled with 6-FAM (blue) fluorescent dyes.
