Research progress on MAFB gene polymorphism and nonsyndromic cleft lip and palate

Nonsyndromic cleft lip with/without cleft palate is a common congenital birth defect of the maxillofacial region. The pathogenic mechanism is related to the interaction of genes and environmental factors. At present, there are many studies on genes, and genome-wide association analysis has found that the new susceptibility gene v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) is associated with the development of nonsyndromic cleft lip with/without cleft palate. This paper reviews the research progress on the correlation between single nucletide polymorphism(SNPs) in MAFB and nonsyndromic cleft lip with/without cleft palate. The results of this review reveal how the MAFB gene is expressed and differentiated in various cell types and plays an important role in maintaining the development of various organs, such as the brain, pancreas, and parathyroid glands. The MAFB gene is significantly associated with the occurrence of nonsyndromic cleft lip with/without cleft palate in the Asian population. rs13041247, rs11696257, rs17820943 and other teratopoietic single nucleotide loci are the most commonly studied teratopoietic single nucleotide loci, and the research conclusions on the correlation between SNPs in MAFB genes are obviously different in different populations. The interaction between the MAFB gene and other susceptibility genes leads to the occurrence of nonsyndromic cleft lip with/without cleft palate; nevertheless, more in-depth research is needed on specific mechanisms and approaches based on the relationship between these two factors
