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.
