中国人群叶酸/同型半胱氨酸代谢基因多态性与非综合征型唇腭裂关联研究
Association study for gene polymorphism of folic acid/homocysteine metabolic pathway and nonsyndromic cleft lip with or without cleft palate in Chinese populations
摘要
Abstract
Objective:To explore the association between 18 candidate genes encoding enzymes on the folate/homocysteine metabolism pathway and non-syndromic cleft lip with or without cleft palate (NSCL/P) in Chinese populations.Methods:A total of 806 NSCL/P trios were drawn by an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate genes affecting risks to NSCL/P.The transmission disequilibrium test (TDT) was used for deviation from Mendelian expectations for 257 SNPs in 18 folate/homocysteine metabolism-related genes.The interactions between markers in these gene and environmental risk factors were also tested using conditional Logistic regressions.Results:Although four SNPs (rs6428977,rs12060264,rs7730643 and rs4920037) showed nominal significant association with NSCL/P in the TDT on 806 NSCL/P trios (P <0.05),no significant evidence of linkage and association remained in all the SNPs after Bonferroni correction.Similar tests for interactions between genes and maternal smoking,environmental tobacco smoke,alcohol consumption and multi-vitamin supplementation during pregnancy did not attain statistical significance after correction for multiple comparisons.Conclusion:Folate/homocysteine metabolism-related genes could not influence the risk of NSCL/P.关键词
