 Until October 2017, all variants with the ClinVar types copy number gain/loss
 and DbVar "nsv" accessions were put in the CNV category.  Due
 to the ClinVar type not capturing this information anymore, anything longer
 than 100bp is now considered a CNV.</p>
 
 <p>
 Entries in the ClinVar CNV track are colored
 <b><font color="red">red for loss</font></b> and
 <B><font color="blue">blue for gain</font></b>.
 </p>
 
 <p>
 Entries in the ClinVar short variants track are shaded by clinical annotation:
 <b><font color="red">red for pathogenic</font></b>,
 <B><font color="#888">dark grey for uncertain significance or not provided</font></b> and
+<B><font color="#000088">dark blue for variant of uncertain significance</font></b> and
 <B><font color="#ADD8E6">light blue for conflicting</font></b> and
 <B><font color="green">green for benign</font></b>.

 The score of the variants is the number of "stars" in ClinVar. On the track configuration page (above), you can filter the track to show only variants with more than a certain number of stars. For more information on the star rating, see the <a href="https://www.ncbi.nlm.nih.gov/clinvar/docs/review_status/"

 <p>For the human genome version hg19: the hg19 genome released by UCSC in 2009 had a 
 mitochondrial genome "chrM" that was not the same as the one later used for most
 databases like ClinVar. As a result, we added the official mitochondrial genome
 in 2020 as "chrMT" and all mitochondrial annotations of ClinVar and most other
-databases are shown on the mitochondrial genome called "chrMT".
+databases are shown on the mitochondrial genome called "chrMT". For full description
+of the issue of the mitochondrial genome in hg19, please see the

 <h2>Data updates</h2>
 <p>ClinVar publishes a new release on the 
 <a href="https://www.ncbi.nlm.nih.gov/feed/rss.cgi?ChanKey=ClinVarNews">first Thursday every month</a> 
 and this track is updated automatically at most six days 
 later. The exact date of our last update is shown when you click onto any variant. 
 You can find the previous versions of the track organized by month on our
 downloads server in the 
 <a href="http://hgdownload.soe.ucsc.edu/goldenPath/hg19/archive/clinvar/" target="_blank">archive</a>
 directory. To access one of these previous versions, paste the URL to one of
