ERCC4 and breast cancer: Autoantibodies in BC targeted four clones of a non-coding sequence (GenBank accession: JK649852, a phage from our earlier work) that map to an ultra-conserved non-coding region in UCSC Genome Browser’s phyloP analysis of MultiZ 100-species genome alignments and is located ∼370 kb upstream of the ERCC4 gene (Figure 6A).
