RESUMO

RESUMO Introdução: Muitos estudos publicados estimaram a associação dos polimorfismos rs2435357 e rs1800858 do proto-oncogene rearranjado durante a transfecção (RET) com o risco de doença por Hirschsprung (HSCR). No entanto, os resultados permanecem inconsistentes e controversos. Objetivo: Realizar metanálise para obter estimativa mais precisa da associação dos polimorfismos rs2435357 e rs1800858 no proto-oncogene RET com risco de HSCR. Método: A literatura elegível foi pesquisada pelo PubMed, Google Scholar, EMBASE e CNKI até 30 de junho de 2018. Resultados: Um total de 20 estudos, incluindo dez (1.136 casos 2.420 controles) para rs2435357 e dez (917 casos 1.159 controles) para rs1800858 foram incluídos. Os resultados globais indicaram que o rs2435357 (modelo alelo: OR=0,230, IC 95% 0,178-0,298, p=0,001; modelo homozigoto: OR=0,079, IC 95% 0,048-0,130, p=0,001; modelo heterozigoto: OR=0,149 , IC 95% 0,048-0,130, p=0,001, modelo dominante: OR=0,132, IC 95% 0,098-0,179, p=0,001 e modelo recessivo: OR=0,239, IC 95% 0,161-0,353, p=0,001) e rs1800858 (modelo alelo: OR=5,594, IC 95% 3,653-8,877, p=0,001; modelo homozigoto: OR=8,453, IC 95% 3,783-18,890, p=0,001; modelo dominante: OR=3,469, IC 95% 1,881- 6,396, p=0,001 e modelo recessivo: OR=6,120, 95% CI 3,608-10,381, p=0,001) polimorfismos foram associados com o aumento do risco de HSCR em geral. Conclusões: Os resultados sugerem que os polimorfismos rs2435357 e rs1800858 no proto-oncogene RET podem estar associados ao HSCR.ABSTRACT Introduction: Many published studies have estimated the association of rs2435357 and rs1800858 polymorphisms in the proto-oncogene rearranged during transfection (RET) gene with Hirschsprung disease (HSCR) risk. However, the results remain inconsistent and controversial. Aim: To perform a meta-analysis get a more accurate estimation of the association of rs2435357 and rs1800858 polymorphisms in the RET proto-oncogene with HSCR risk. Methods: The eligible literatures were searched by PubMed, Google Scholar, EMBASE, and Chinese National Knowledge Infrastructure (CNKI) up to June 30, 2018. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the susceptibility to HSCR. Results: A total of 20 studies, including ten (1,136 cases 2,420 controls) for rs2435357 and ten (917 cases 1,159 controls) for rs1800858 were included. The overall results indicated that the rs2435357 (allele model: OR=0.230, 95% CI 0.178-0.298, p=0.001; homozygote model: OR=0.079, 95% CI 0.048-0.130, p=0.001; heterozygote model: OR=0.149, 95% CI 0.048-0.130, p=0.001; dominant model: OR=0.132, 95% CI 0.098-0.179, p=0.001; and recessive model: OR=0.239, 95% CI 0.161-0.353, p=0.001) and rs1800858 (allele model: OR=5.594, 95% CI 3.653-8.877, p=0.001; homozygote model: OR=8.453, 95% CI 3.783-18.890, p=0.001; dominant model: OR=3.469, 95% CI 1.881-6.396, p=0.001; and recessive model: OR=6.120, 95% CI 3.608-10.381, p=0.001) polymorphisms were associated with the increased risk of HSCR in overall. Conclusions: The results suggest that the rs2435357 and rs1800858 polymorphisms in the RET proto-oncogene might be associated with HSCR risk.
