Figure 2.

Evidence of expansions at multiple chromosomal sites. The fourteen resequencing targets examined had extraneous sequence in the published version. In each case, correction of the error required large deletions (over 300 bp). For each of the targets examined, the closed arrowhead indicates the band observed upon amplification with the PCR primers listed, whereas the open arrowhead indicates the size of the product expected by the sequence in the published version 1.0. Marker sizes are indicated in kb.
