OBJECTIVES: This study aimed to reveal the association between single-nucleotide polymorphism of NTN1 and subtypes of non-syndromic cleft lip with or without cleft palate (NSCL/P) in Han Chinese Population.
DESIGN: Initially, we selected three single-nucleotide polymorphisms (SNP) (rs4791331, rs4791774 and rs9891446) in NTN1 from previous genetic studies. Then we recruited two Han Chinese cohorts (2004 cases and 1823 controls) and divided cases into subgroups: non-syndromic right-side cleft lip, non-syndromic left-side cleft lip, non-syndromic bilateral cleft lip and non-syndromic cleft lip with palate to further evaluate the associations between the subtypes of NSCL/P and SNPs in NTN1. PLINK and Haploview program were utilized to analyze the data.
RESULTS: In the association analysis under additive model, we found that G allele at rs9891446 could specifically increase the risk of right-side cleft lip (P = 0.0073, OR = 1.44, 95%CI: 1.1-1.88), which was consistent with the results of association analysis under genotypic model.
CONCLUSION: This study showed that rs9891446 of NTN1 was specifically associated with right-side cleft lip in Han Chinese, which indicates that different subtypes of non-syndromic cleft lip have distinct genetic background.
