Figure 3. Partial sequence of the intron (lower case letters) between exons 3 and 4

The red nucleotides illustrate the end of exon 3. The nucleotides in blue show the 5' and 3' ends of the 165 bp sequence that is unique to Variant 3 (Figure 1). The sequences flanking this novel exon are labeled as introns and their lengths (in bp) are given.
