Recurrent, de novo 8q13.2-13.3 microdeletion identified in four cases with Branchio-oto-renal syndrome. A Array data plots showing 2.6 Mb deletions ranging from 70,062,624-72,714,795 at 8q13.2-13.3 in cases 1 and 2. B The UCSC Genome Browser custom tracks (chr8:69,393,700-73,407,100, genome build hg18) demonstrating deletion of 8q13.2-13.3 in five unrelated cases with BOR syndrome/hearing problems (labeled as *), which cover 10 Refseq genes (LOC100505718, SULF1, SLCO5A1, PRDM14, NCOA2, TRAM1, LOC286190, LACTB2, XKR9, EYA1). Red indicates deletion and blue indicates duplication. Note: ns1492921 in the ISCA data represents the same case as case 2 in this study.
