RPCs with parental gene alignments that extend beyond the known transcript start and end points indicate the existence of longer transcripts. Numbers in parentheses are the number of sequences in the sequence category that corresponds to the base pair extension. HMGB1 query sequence NM_002128.2 is an updated version of the similar sequence D53874.1 used in Table 1.
