These included one previously described polymorphism in exon 4 (831G/A) seen in association with Hirschsprung disease and 6 novel polymorphisms identified in exons 1 (178G/A), 2 (552C/T and 561C/T), and 3 (702C/T).
Detection of the 178G/A polymorphism in only non-syndromic HSCR patients, provide further support for an important role of specific sequence variants in the EDNRB gene in the HSCR/Down's syndrome phenotype.
