ABSTRACT
<p><b>OBJECTIVE</b>To explore congenital heart diseases (CHD) in their offsprings in association with parental methylenetetrahydrofolate reductase (MTHFR) gene C677T, cystathionine beta-synthase (CBS) gene T833C, and environmental factors.</p><p><b>METHODS</b>A 11 case-control study was carried out to investigate 115 pairs of case and controlled children and their parents, and the parents' MTHFR gene 677 C-->T mutation and CBS gene 833 T-->C mutation were also identified. The possible risk factors were analysed by simple and multiple factors logistic regression methods.</p><p><b>RESULTS</b>Results revealed that 5 factors were related to the occurrence of CHD in the offsprings maternal exposures to pesticides in the early stage of pregnancy (OR = 8.62), suffering from diseases during pregnancy (OR = 2.069), catching cold in the early stage of pregnancy (OR = 4.125), under depressed or nervous condition during pregnancy (OR = 4.653), maternal MTHFR 677TT genotype (OR = 3.872).</p><p><b>CONCLUSION</b>These results suggested that maternal MTHFR 677TT genotype was one of the risks to the occurrence of CHD in offspring but parents' CBS gene 833 T-->C mutation did not get involved in CHD. In addition, the occurrence of CHD was related to maternal exposures to pesticides, catching a cold, suffering from diseases, depressed or under nervous condition in the early stage of pregnancy or during pregnancy.</p>
