 The views available for this track include:

   <ul>
     <li>
     <em>RefSeq All</em> &ndash; all curated and predicted annotations provided by 
     RefSeq.</li>
     <li>

-    annotations whose accessions begin with NM, NR,  NP or YP. (YP annotations exist for human only)</li>
+    annotations whose accessions begin with NM, NR,  NP or YP. <small>(NP and YP are used only for
+    protein-coding genes on the mitochondrion; YP is used for human only.)</small></li>
     <li>
     <em>RefSeq Predicted</em> &ndash; subset of RefSeq All that includes those annotations whose 
     accessions begin with XM or XR.</li>
     <li>
     <em>RefSeq Other</em> &ndash; all other annotations produced by the RefSeq group that 
     do not fit the requirements for inclusion in the <em>RefSeq Curated</em> or the 
     <em>RefSeq Predicted</em> tracks.</li>
     <li>
     <em>RefSeq Alignments</em> &ndash; alignments of RefSeq RNAs to the $organism genome provided
     by the RefSeq group.</li>

    <em>RefSeq Diffs</em> &ndash; alignment differences between the $organism reference genome(s) 
-   and RefSeq transcripts. <b>Note</b>: track not currently available for every assembly.
