Localization of C-terminally GFP-tagged EDNRB fusion proteins in HEK293 cells.
<p>A: HEK293 cells were transiently transfected with wild-type EDNRB isoform 1 (Iso 1) or mutant EDNRB isoform 1 (M1V). Signals were observed at the plasma membrane in cells expressing wild-type isform 1 while signals were detected in the cytosol in cells transfected with mutant isoform 1. B: HEK293 cells were transiently transfected with wild-type EDNRB isoform 3 (Iso 3) or mutant EDNRB isoform 3 (M91V). Signals were found in the cytosol in cells transfected with either wild-type or mutant isoform 3. C. HEK293 cells were transiently transfected with GFP vector only. Shown are the representative iamges. Bars, 50 µm.</p

Genome-Wide Copy Number Analysis Uncovers a New HSCR Gene: <em>NRG3</em>
<div><p>Hirschsprung disease (HSCR) is a congenital disorder characterized by aganglionosis of the distal intestine. To assess the contribution of copy number variants (CNVs) to HSCR, we analysed the data generated from our previous genome-wide association study on HSCR patients, whereby we identified <em>NRG1</em> as a new HSCR susceptibility locus. Analysis of 129 Chinese patients and 331 ethnically matched controls showed that HSCR patients have a greater burden of rare CNVs (<em>p</em> = 1.50×10<sup>−5</sup>), particularly for those encompassing genes (<em>p</em> = 5.00×10<sup>−6</sup>). Our study identified 246 rare-genic CNVs exclusive to patients. Among those, we detected a <em>NRG3</em> deletion (<em>p</em> = 1.64×10<sup>−3</sup>). Subsequent follow-up (96 additional patients and 220 controls) on <em>NRG3</em> revealed 9 deletions (combined <em>p</em> = 3.36×10<sup>−5</sup>) and 2 <em>de novo</em> duplications among patients and two deletions among controls. Importantly, <em>NRG3</em> is a paralog of <em>NRG1</em>. Stratification of patients by presence/absence of HSCR–associated syndromes showed that while syndromic–HSCR patients carried significantly longer CNVs than the non-syndromic or controls (<em>p</em> = 1.50×10<sup>−5</sup>), non-syndromic patients were enriched in CNV number when compared to controls (<em>p</em> = 4.00×10<sup>−6</sup>) or the syndromic counterpart. Our results suggest a role for <em>NRG3</em> in HSCR etiology and provide insights into the relative contribution of structural variants in both syndromic and non-syndromic HSCR. This would be the first genome-wide catalog of copy number variants identified in HSCR.</p> </div

CNV burden for syndromic (Syn) and non-syndromic (Non-syn) HSCR patients relative to controls (Ctrl).
<p>The burden was measured with reference to the (A) size, (B) rate and (C) gene count of CNVs. Red and blue bars denote the mean value of the corresponding test for deletion and duplication respectively. Summary statistics as well as conditional permutation <i>p</i>-value was shown in (D).</p
