先天性巨结肠是一种严重的多因素遗传性疾病。基因芯片研究表明GAL、GAP 43和NRSN 1可能与HSCR的风险改变有关。因此,我们专注于GAL,GAP 43和NRSN 1的遗传变异,以及参与HSCR易感性的基因-基因相互作用。我们采用了病例对照研究和MassArray系统与交互网络分析相结合的策略。对于GAL、GAP 43和NRSN 1,在104名散发性HSCR受试者和151名汉族对照者中评估了共18个多态性。我们发现HSCR组和对照组在5个遗传变异方面存在统计学显著差异。对于每个基因,单倍型结合所有多态性是最显着的。基于SNPsyn、MDR和GeneMANIA分析,我们观察到GAL、GAP 43、NRSN 1和我们先前鉴定的GABRG 2、PTCH 1之间存在显著的基因-基因相互作用。我们的研究首次表明GAL、GAP 43和NRSN 1内的遗传变异以及相关的基因-基因相互作用网络可能参与了中国汉族人群中HSCR易感性的改变,这可能为HSCR的发病机制提供更多信息。
Hirschsprung disease (HSCR) is a severe multifactorial genetic disorder. Microarray studies indicated GAL,GAP43 and NRSN1 might contribute to the altered risk in HSCR. Thus, we focused on genetic variations in GAL,GAP43 and NRSN1, and the gene‐gene interactions involved in HSCR susceptibility. We recruited a strategy combining case‐control study and MassArray system with interaction network analysis. For GAL,GAP43 and NRSN1, a total of 18 polymorphisms were assessed in 104 subjects with sporadic HSCR and 151 controls of Han Chinese origin. We found statistically significant differences between HSCR and control groups at 5 genetic variants. For each gene, the haplotypes combining all polymorphisms were the most significant. Based on SNPsyn, MDR and GeneMANIA analyses, we observed significant gene‐gene interactions among GAL,GAP43,NRSN1 and our previous identified RELN,GABRG2 and PTCH1. Our study for the first time indicates that genetic variants within GAL,GAP43 and NRSN1 and related gene‐gene interaction networks might be involved in the altered susceptibility to HSCR in the Han Chinese population, which might shed more light on HSCR pathogenesis.
