Figure 4. Schematic representation of the 3' end of the exon 6 of the LCA5 gene. The figure represents 3' portion of the normal and mutant sequence of the exon 6 of the LCA5 gene. Nucleotides in uppercase represent exonic sequence and that in small lower case represent intronic sequences. The nucleotide in uppercase and in bold represent the last base of the exon and the site of mutation. The first vertical bar in the normal sequence represent the real splice donor site and the second vertical bar represent additional/alternative splice donor site, which is activated in the event of absence of the real splice donor site.
