Abstract
Background Hirschsprung’s disease (HSCR) is a heterogeneous congenital malformation of the enteric nervous system with a complex genetic etiology. We investigated if there was an association between Neuregulin-1 (NRG1) rs7835688 G > C, rs16879552 T > C and rs2439302 G > C polymorphisms and the risk of HSCR. Methods: We determined and compared the frequency of NRG1 polymorphisms rs7835688 G > C, rs16879552 T > C and rs2439302 G > C in 70 children with HSCR and 90 controls by TaqMan SNPs genotyping assays. Results: No significant differences in allele or genotype frequencies of NRG1 rs7835688 G > C, rs16879552 T > C and rs2439302 G > C polymorphisms were observed between HSCR cases and controls. Analyses showed that the NRG1 rs7835688 G > C, rs16879552 T > C and rs2439302 G > C polymorphisms were not significantly associated with an increased risk of non-syndromic HSCR. Conclusions: Our findings suggested that NRG1 rs7835688 G > C, rs16879552 T > C and rs2439302 G > C polymorphisms are not a risk factor in development of HSCR.
