 <p>
 CADD scores strongly correlate with allelic diversity, pathogenicity of both
 coding and non-coding variants, experimentally measured regulatory effects,
 and also rank causal variants within individual genome sequences with a higher
 value than non-causal variants. 
 Finally, CADD scores of complex trait-associated variants from genome-wide
 association studies (GWAS) are significantly higher than matched controls and
 correlate with study sample size, likely reflecting the increased accuracy of
 larger GWAS.

 <h2>Display Conventions and Configuration</h2>

-There are six subtracks of this track: four for every possible single nucleotide mutation, 
+There are six subtracks of this track: four for single-nucleotide mutations,
+one for each base, showing all possible substitutions, 
 one for insertions and one for deletions. All subtracks show the CADD Phred
 score on mouseover.</p>
 <p>
 PHRED-scaled scores are normalized to all potential &#126;9 billion SNVs, and
 thereby provide an externally comparable unit for analysis. For example, a
 scaled score of 10 or greater indicates a raw score in the top 10% of all
 possible reference genome SNVs, and a score of 20 or greater indicates a raw
 score in the top 1%, regardless of the details of the annotation set, model
 parameters, etc.
 </p>
 
 <p>
 <b>Single nucleotide variants (SNV):</b> For SNVs, at every
 genome position, there are three values per position, one for every possible
-nucleotide mutation. The fourth value, &quot;no mutation&quot;, e.g. A to A, is always
-set to zero.<br>
-When using this track, please zoom in until you can see every basepair at the
-top of the display. Otherwise, there are several nucleotides under your mouse
-cursor per pixel and instead of an actual score, the tooltip text can only show
-the average score of all nucleotides under the cursor, which is indicated by
-the prefix &quot;~&quot; in the mouseover and averages of scores are not useful for any
+nucleotide mutation. The fourth value, &quot;no mutation&quot;, representing 
+the reerence allele, e.g. A to A, is always set to zero.

 <p><b>Insertions and deletions:</b> Scores are also shown on mouseover for a
 set of insertions and deletions. On hg38, the set has been obtained from
 Gnomad3. On hg19, the set of indels has been obtained from various sources
 (gnomAD2, ExAC, 1000 Genomes, ESP). If your insertion or deleletion of interest
 is not in the track, you will need to use CADD's

 to obtain them.</p>
