Abstract

BACKGROUND: Nonsyndromic cleft lip with or without cleft palate (CL/P) is a common complex birth defect caused by the interaction between multiple genes and environmental factors. METHODS: Five hundred and eighty-seven single nucleotide polymorphisms in 40 candidate genes related to orofacial clefting were tested for association with CL/P in a clefting sample composed of 300 patients and 606 controls from Estonian, Latvian, and Lithuanian populations. RESULTS: In case-control comparisons, the minor alleles of FGF1 rs34010 (p = 4.56 × 10-4), WNT9B rs4968282 (p = 0.0013), and FOXE1 rs7860144 (p = 0.0021) were associated with a decreased risk of CL/P. Multiple haplotypes in FGF1, FOXE1, and TIMP2 and haplotypes in WNT9B, PVRL2, and LHX8 were associated with CL/P. The strongest association was found for protective haplotype rs250092/rs34010 GT in the FGF1 gene (p = 5.01 × 10-4). The strongest epistatic interaction was observed between the COL2A1 and WNT3 genes. CONCLUSIONS: Our results provide for the first time evidence implicating FGF1 in the occurrence of CL/P, and support TIMP2 and WNT9B as novel loci predisposing to CL/P. We have also replicated recently reported significant associations between variants in or near FOXE1 and CL/P. It is likely that variation in FOXE1, TIMP2, and the FGF and Wnt signaling pathway genes confers susceptibility to nonsyndromic CL/P in Northeastern European populations.
