Identification of regulatory deletions telomeric to <i>PAX6</i>.
<p>Regulatory deletions telomeric to <i>PAX6</i> were identified in individual 1514 (chr11:30,874,642–31,654,833), individual 753 (chr11:30,967,000–31,704,000), individual 555 (chr11:31,108,579–31,649–842), individual 2014 (chr11:31,234,395–31,751,815) and individual 659 (chr11:31,379,000–31,708,000). The schematic diagram shows how the ‘critical region’ (delimited by grey dotted lines) required for <i>PAX6</i> transcriptional activation was delineated by combining our data with published deletions with known coordinates [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153757#pone.0153757.ref055" target="_blank">55</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153757#pone.0153757.ref067" target="_blank">67</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153757#pone.0153757.ref068" target="_blank">68</a>]. <i>PAX6</i> regulatory deletions from the present study are shown by red blocks. Genes transcribed on the forward strand are in blue and those transcribed on the reverse strand are in green, also indicated by arrows. Genomic coordinates are based on the Human Genome Assembly hg18.</p

Identification of a potential <i>PITX2</i> regulatory deletion.
<p>Genome-wide array CGH identified a deletion of approximately 3.5 Mb in individual 1194 (chr4:111,994,000–115,504,000) (red bar). The deletion is located telomeric to the <i>PITX2</i> gene on chromosome 4. The positions of conserved elements (CE) in the deleted region, as identified by Volkmann et al., 2011 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0153757#pone.0153757.ref047" target="_blank">47</a>] are marked by orange ellipses. Genes transcribed on the forward strand are in blue and those transcribed on the reverse strand are in green, also indicated by arrows. Genomic coordinates are shown on the x-axis and are based on the Human Genome Assembly hg18.</p
Mutation analysis of the <i>FOXC1</i> locus.
<p><b>(A)</b> Genome-wide array CGH identified two deletions encompassing the <i>FOXC1</i> gene in individuals 1449 (chr6:1,543,591–1,675,085) and 1246 (chr6:1,543,591–1,675,085). <b>(B)</b> Direct sequencing of the <i>FOXC1</i> coding region identified a heterozygous substitution in individual 1839 (c.235C>A, p.(Pro79Thr)) and another in individual 1634 (c.302T>C, p.(Leu101Pro)). <i>FOXC1</i> mutation screening in unaffected parents of both patients showed that the mutations had occurred <i>de novo</i>. The locations of both mutations within the fork-head domain of the FOXC1 protein are indicated by vertical arrows. Genes transcribed on the forward strand are in blue and those transcribed on the reverse strand are in green, also indicated by arrows. Genomic coordinates are based on the Human Genome Assembly hg18. The genomic sequence identifier for <i>FOXC1</i> is NG_009368.</p
Identification of <i>PAX6</i> whole-gene deletions.
<p>Genome-wide array CGH analysis identified a 650 kb deletion in individual 2193 (chr11:31,199,000–31,849,000), a 520 kb deletion in individual 377 (chr11:31,394,000–31,914,000), a 154 kb deletion in individual 1510 (chr11:31,779,000–31,933,000) and a 96 kb deletion in individual 1977 (chr11:31,698,271–31,794,414), all involving <i>PAX6</i>. Red bars show the position of the deletions. Genes transcribed on the forward strand are in blue and those transcribed on the reverse strand are in green, also indicated by arrows. Genomic coordinates are based on the Human Genome Assembly hg18.</p
