Effects of NRG1 Polymorphisms on Hirschsprung's Disease Susceptibility: A Meta-analysis.

ABSTRACT: Substantial resources have been devoted to evaluate the relationship between NRG1 variants rs7835688 and rs16879552 and Hirschsprung's Disease (HSCR) but no consistency exists. This meta-analysis aimed to assess the association between the two SNPs and HSCR. PubMed, EMBASE, and Chinese Biological Medicine databases were searched for studies potentially eligible up to March, 2017. The summary odds ratios (ORs) with 95% CIs were calculated from different genetic models. Nine case-control studies (8 for both and 1 for rs16879552 only) involving 1984 HSCR patients and 4220 controls were identified. The combined results showed a significant association between HSCR risk and rs7835688 in all genetic models (per-allele model: OR?=?1.66, 95% CI?=?1.35-2.05; P?=?1.940E-06). Rs16879552 was significantly associated with HSCR in per-allele (OR?=?1.50, 95% CI?=?1.27-1.76; P?=?1.087E-06), additive and recessive model, except for dominant model. Stratified analysis by ethnicity showed that rs7835688 and rs16879552 were only causative for Asians, but not risk locus for Caucasians. Furthermore, pooled data based on segment length indicated that individuals with rs7835688 experienced a significantly higher risk for short-segment HSCR in all genotypes; but rs16879552 was only found to be associated with long-segment HSCR/ total colonic aganglionosis at the allele level.

Project description:BackgroundMany publications have evaluated the correlation between RET, PHOX2B polymorphisms and Hirschsprung's disease with conflicting results. We performed this meta-analysis to clarify the association of RET, PHOX2B polymorphisms with HSCR.MethodsWe searched Pubmed, Elsevier Science Direct, China National Knowledge Infrastructure database, Chinese Biomedical database, Google scholar. The combined odds ratio (OR) with 95% CI was calculated to estimate the strength of the association. Heterogeneity and publication bias were also assessed.ResultsIn total, 16 studies concerning RET and 4 studies concerning PHOX2B were included in the meta-analysis. The effects of five polymorphisms of RET (rs1800858, rs1800860, rs1800861, rs10900297, rs2435357) and one polymorphism (rs28647582) of PHOX2B were evaluated. We found a significant correlation between RET polymorphisms and HSCR. For rs1800858, the overall ORs (95% CI) of the A versus G, AA versus GG, AA/AG versus GG and AA versus GG/AG were 3.81 (2.28-6.35); 8.36 (3.45-20.25); 3.59 (1.83-7.02); and 6.60 (3.66-11.89). For rs1800861, the comparison of subjects in the G versus T, GG versus TT, GG/TG versus TT and GG versus TT/TG were 2.85(1.81-4.47); 5.38(2.68-10.80); 3.07(2.17-4.34) and 4.14(1.84-9.30) respectively. For rs10900297, the comparison results showed statistically significant. (OR(C versus A) = 5.05,95%CI = 4.16-6.13; OR(CC versus AA) = 9.73, 95%CI = 5.94-15.94; OR(CC/AC versus AA) = 5.31, 95%CI = 3.27-6.82; OR(CC versus AC/AA) = 7.06,95%CI = 5.60-8.91.) But, for rs1800860, the GG/GA versus AA did not reach statistical association (OR = 3.77, 95% CI = 0.94-15.07) and the G versus A, GG versus AA, GG versus GA/AA were 2.23 (1.60-3.11);4.56 (1.14-18.27); 2.38 (1.66-3.43) respectively. For rs2435357, the T versus C, TT versus CC, TT/TC versus CC and TT versus CC/TC were 4.53 (3.27-6.27); 11.44 (5.67-23.10); 4.04 (2.92-5.57), and 9.01(5.25-15.46).The single polymorphism of PHOX2B gene wasn't related to the risk for HSCR.ConclusionsThis meta-analysis shows a significant association between RET polymorphisms and HSCR.
