  1. Eight genomic regions containing predicted exons were examined. 0 indicates that the exon was absent (one band at the smallest expected size); 1 indicates the exon was present, but not alternatively spliced (one band seen at the largest expected size); 2 indicates that the exon was present and alternatively spliced (2 bands observed). ** exon not transcribed in brain.
