Abstract: Background: Interferon regulatory factor 6 (IRF6) gene has emerged as a potential susceptibility gene for non-syndromic cleft lip and/or palate (NSCL/P) in different populations. The aim of this study was to determine the association of IRF6 rs2235371 and rs642961 polymorphisms with NSCL/P in a Brazilian population. Methods: Two hundred and twenty-eight patients affected by NSCL/P and 126 healthy individuals were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. Results: Overall genotype distributions of rs2235371 and rs642961 polymorphisms were as expected by Hardy-Weinberg equilibrium test. The rs2235371 polymorphic genotype GA was identified in 10.1% of the patients with NSCL/P and in 10.3% of the control group, revealing no statistical difference. Similarly, the frequency of rs642961 minor genotypes (GA and AA) was quite similar between control group (28.6%) and NSCL/P group (25.4%), without significant difference. Conclusion: Our findings are consistent with a lack of involvement of IRF6 rs2235371 and rs642961 polymorphisms in the NSCL/P pathogenesis in the Brazilian population.
