Non-syndromic cleft lip with or without cleft palate (NSCLP) is a common complex birth defect. MAFB (v-maf musculoaponeurotic fibrosarcoma oncogene homolog B) is a new gene that may be involved in susceptibility to cleft lip with or without cleft palate (CL/P). To further assess its role in NSCLP, we investigated 3 identified single nucleotide polymorphisms in MAFB (rs13041247, rs6065259, and rs11696257) and examined them for association with NSCLP in 344 patients and 324 healthy controls in a northern Chinese Han population with a high incidence of the syndrome. Peripheral blood samples were taken when patients enrolled in the study and DNA samples were extracted from the blood. The 3 single nucleotide polymorphisms were genotyped using a mini-sequencing method (Snapshot((R)) Multiplex System for SNP genotyping, Life Technologies Ltd, Paisley, UK). We found that rs6065259 was the most important single nucleotide polymorphism in MAFB (OR6065259-AA = 0.45; 95% CI: 0.28 to 0.71; p = 0.0027), followed by rs13041247; however, no association was found between rs11696257 and NSCLP. Our study provides further evidence regarding the role of MAFB variations in the development of NSCLP in this northern Chinese Han population.
