Hirschsprung has a complex genetic aetiology and mutations in several genes have been related to the disease. There is a clear predominance of missense\/nonsense mutations in these genes whereas copy number variations (CNVs) have been seldom described, probably due to the limitations of conventional techniques usually employed for mutational analysis. In this study, we have looked for CNVs in some of the genes related to Hirschsprung (<jats:italic>EDNRB, GFRA1, NRTN<\/jats:italic> and <jats:italic>PHOX2B<\/jats:italic>) using the Multiple Ligation-dependent Probe Amplification (MLPA) approach.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>CNVs screening was performed in 208 HSCR patients using a self-designed set of MLPA probes, covering the coding region of those genes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>A deletion comprising the first 4 exons in <jats:italic>GFRA1<\/jats:italic> gene was detected in 2 sporadic HSCR patients and <jats:italic>in silico<\/jats:italic> approaches have shown that the critical translation initiation signal in the mutant gene was abolished. In this study, we have been able to validate the reliability of this technique for CNVs screening in HSCR.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>The implemented MLPA based technique presented here allows CNV analysis of genes involved in HSCR that have not been not previously evaluated.
