Abstract:
Objective:To explore the association and gene-environment interaction between single nu-cleotide polymorphisms (SNPs)involved in cell-cell adhesion and non-syndromic cleft lip with or without cleft palate (NSCL/P)among Chinese population.Methods:A total of 806 NSCL/P trios were drawn by an international consortium,which conducted a genome-wide association study (GWAS)using a case-parent trio design to investigate genes affecting risks to NSCL/P.The transmission disequilibrium test (TDT)was used to explore the association between cell-cell adhesion genes,including CDH1,CT-NNB1,PVRL1,PVRL2,PVRL3,ACTN1,VCL,LEF1,and NSCL/P.Conditional Logistic regression models were used to estimate effects on risk of exposed and unexposed children.Four common maternal exposures including maternal smoking,environmental tobacco smoke,alcohol consumption and multivita-min supplementation during pregnancy were included in this study.Results:A total of 226 SNP markers were tested after quality control in this study.Although 23 SNPs in three genes (CTNNB1,CDH1, ACTN1)showed nominal significant association with NSCL/P in the TDT (P <0.05).There were no sig-nificant evidence of linkage and association that remained in the transmission disequilibrium test after Bonferroni correction(P >0.000 2).Tests for gene-environment interaction yielded significant results be-tween rs7431 27 in ACTN1 and environmental tobacco smoke (P =0.000 1 )with an estimated OR (case |G and E)=2.00(95%CI:1 .23 -3.26)and OR (case |G no E)=0.59 (95%CI:0.38 -0.90).Among the lower P value results in gene-environment tests,there were no significant results be-tween rs1 475034,rs370535,rs227341 9 in ACTN1,rs1 06871 in CTNNB1 and environmental tobacco smoke interaction.There were also no significant results between rs7634000,rs2971 366,rs2634553, rs1 489032,rs762481 2 in PVRL3 and multivitamin supplementation during pregnancy in gene-environ-ment tests(P >0.000 2).Conclusion:There is no association between cell-cell adhesion genes,inclu-ding CDH1,CTNNB1,PVRL1,PVRL2,PVRL3,ACTN1,VCL,LEF1,and NSCL/P when the genes are considered alone.But our results suggest that SNPs in ACTN1 may influence the risk to NSCL/P through gene-environment interaction.
