 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;, representing 
-the reerence allele, e.g. A to A, is always set to zero.
+the reference allele, e.g. A to A, is always set to zero.
 <br>
 When using this track, zoom in until you can see every basepair at the
 top of the display. Otherwise, there are several nucleotides per pixel under 
 your mouse cursor and instead of an actual score, the tooltip text will show
 the average score of all nucleotides under the cursor. This is indicated by
 the prefix &quot;~&quot; in the mouseover. Averages of scores are not useful for any
 application of CADD.
 </p>
 
 <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
