To access the data, click or select the words “Appendix 4.” The chromosome 14 banding pattern, location from the top of the chromosome and the SIX6 gene locus (in blue) are shown. The coverage track above the reads represents depth of coverage for all reads and the grey bars depict individual sequence reads. Note that exon 2 is fully covered with multiple reads whereas there are no reads (in red) covering exon 1.
