摘要
目的 探讨父母亚甲基四氢叶酸还原酶(MTHFR)基因C677T及胱硫醚β-合酶(CBS)基因T833C与子代先天性心脏病(CHD)发生的关系。方法采用1:1配对病例对照研究方法,分析比较115对CHD患儿与对照儿父母MTHFR及CBS基因型。结果母亲MTHFR基因的C与T等位基因频率比较差异具有统计学意义(P=0.036,OR=1.595,95%CI:1.029~2.471),父母CBS基因型构成及等位基因频率比较差异均无统计学意义。结论 母亲MTHFR基因677TT型可能与子代CHD发生有关。
Objective To explore congenital heart diseases (CHD) in offspring in association with parental MTHFR gene C677T and CBS gene T833C. Methods 1 : 1 case-control study was carried out to investigate 115 pairs case-control children and their parents, and we identified parents' MTHFR gene 677 C→T mutation and CBS gene 833 T→C mutation. Results There were significant differences between maternal MTHFR gene C and T allele frequency (P = 0. 036, OR = 1. 595,95 % CI : 1. 029 → 2. 471 ), whereas between CBS gene T and C allele frequency in both mother and father. Conclusion The results suggest maternal MTHFR 677TT genotype is one of the reasons of the occurrence of CHD in offspring.
