Structured comments provide information on supporting evidence and biological attributes. A portion of the COMMENT section of the NM_006440.4 record is displayed, illustrating the two structured comments. (A) The Evidence Data comment reports supporting evidence for the exon combination represented in the record. (B) The RefSeq Attributes comment reports biological attributes. Each comment type includes the attribute category on the left and supporting evidence on the right. Structured comments include special formatting and are bracketed by START and END to support parsing.
