Association between MAFB rs17820943 and rs6072081 polymorphism and risk of nonsyndromic cleft lip with or without cleft palate: a meta-analysis

While there have been previous studies examining the relation between the rs17820943 and rs6072081 polymorphisms in the v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene and rates of nonsyndromic cleft lip with or without cleft palate (NSCL/P), at present the results of these studies have been inconsistent. This meta-analysis therefore aimed to conduct a more robust assessment of the association between the MAFB rs17820943 and rs6072081 polymorphisms and NSCL/P risk. The Embase, Web of Science, PubMed, the China National Knowledge Internet (CNKI), and Wanfang databases were systematically searched to identify relevant studies. In total, five studies incorporating 2769 patients and 2885 controls were identified assessing the rs17820943 polymorphism and three studies incorporating 1242 patients and 1310 controls assessing the rs6072081 polymorphism were identified. This analysis revealed the MAFB rs17820943 and rs6072081 polymorphisms to be linked to a significantly reduced NSCL/P risk (rs17820943: C vs T: OR = 0.76, 95% CI = 0.70-0.82; CC vs CT: OR = 0.75, 95% CI = 0.67-0.85; CC vs TT: OR = 0.58, 95% CI = 0.49-0.67; CC + CT vs TT: OR = 0.67, 95% CI = 0.59-0.77; CT + TT vs CC: OR = 1.43, 95% CI = 1.28-1.60; rs6072081: A vs G: OR = 0.77, 95%CI = 0.68-0.86; AA vs AG: OR = 0.76, 95%CI = 0.64-0.90; AA vs GG: OR = 0.58, 95%CI = 0.45-0.74; AA + AG vs GG: OR = 0.68, 95%CI = 0.54-0.84; AG + GG vs AA: OR = 1.40, 95% CI = 1.19-1.65). The results of the present meta-analysis indicate that in an East Asian population, for both rs17820943 and rs6072081 were associated with NSCL/P.

Association between BMP4 gene polymorphisms and cleft lip with or without cleft palate in a population from South China

ObjectivePrevious studies have suggested an association between several polymorphisms of the BMP4 gene and susceptibility to non-syndromic cleft lip with or without cleft palate (NSCL/P) in various populations. However, this association may vary according to ethnic group and the form of NSCL/P. This study analyzed the association between the BMP4 gene polymorphisms rs762642, rs17563, and rs10130587 with the risk of cleft lip only (CLO), cleft palate only (CPO), and cleft lip with palate (CLP) in a population from South China.MethodsThis case-control study included 165 patients with NSCL/P (53 patients with CPO, 52 with CLO, and 60 with CLP) and 52 healthy volunteers. Peripheral blood samples were collected from all subjects to genotype the rs762642, rs17563, and rs10130587 polymorphisms by direct sequencing. Genotype and allelic frequencies of these polymorphisms were compared between healthy volunteers and patients with various forms of NSCL/P.ResultsThe genotype and allelic frequencies of rs762642 differed significantly between subgroups (CPO and CLP) and normal controls, whereas a significant difference was observed only in the CLO subgroup for the rs17563 polymorphism and in the CLO and CLP groups for the rs10130587 polymorphism. In addition, we identified a novel association of a BMP4 gene polymorphism, which was in linkage disequilibrium with the rs10130587 polymorphism, with CLO and CLP.ConclusionThe BMP4 gene polymorphisms rs762642, rs17563, and rs10130587 exhibit different associations with different forms of NSCL/P, suggesting that different forms of NSCL/P may have different etiologies.

Gene-gene interaction for nonsyndromic cleft lip with or without cleft palate in Chilean case-parent trios

ObjectiveNonsyndromic cleft lip with or without cleft palate (NSCL/P) is a birth defect for which several genes susceptibility genes been proposed. Consequently, it has been suggested that many of these genes belong to common inter-related pathways during craniofacial development gene-gene interaction. We evaluated the presence of gene-gene interaction for single nucleotide polymorphisms within interferon regulatory factor 6 (IRF6), muscle segment homeobox 1 (MSX1), bone morphogenetic protein 4 (BMP4) and transforming growth factor 3 (TGFB3) genes in NSCL/P risk in Chilean case-parent trios.DesignFrom previous studies, we retrieved genotypes for 13 polymorphic variants within these four genes in 152 case-parent trios. Using the trio package (R) we evaluate the gene-gen interaction in genetic markers pairs applying a 1°-of-freedom test (1df) and a confirmatory 4°-of-freedom (4df) test for epistasis followed by both a permutation test and a Benjamini-Hochberg test for multiple comparisons adjustment.ResultsWe found evidence of gene-gene interaction for rs6446693 (MSX1) and rs2268625 (TGFB3) (4df p = 0.024; permutation p = 0.015, Benjamini-Hochberg p = 0.001).ConclusionsA significant gene-gene interaction was detected for rs6446693 (MSX1) and rs2268625 (TGFB3). This finding is concordant with research in animal models showing that MSX1 and TGFB3 are expressed in common molecular pathways acting in an epistatic manner during maxillofacial development.

VAX1 gene associated non-syndromic cleft lip with or without palate in Western Han Chinese

ObjectiveNon-syndromic cleft lip with or without palate (NSCL/P) is one of the most common human birth defects, it results from multiple genetic and environmental risk factors. Recently, GWA studies identified associations between NSCL/P and two genetic risk loci, rs7078160 and rs4752028, at VAX1.DesignCurrently, we tried to investigate the roles of the two loci among 302 NSCL/P trios (129 non-syndromic cleft lip only (NSCLO) trios and 173 non-syndromic cleft lip and cleft palate (NSCLP) trios) from Western Han Chinese. The two SNPs were genotyped by SNPscan method; Hardy–Weinberg equilibrium test, allelic TDT and parent-of-origin effect were performed by PLINK software, and genotypic TDT and haplotype by FBAT software.ResultsAllelic TDT analysis revealed allele A at rs7078160 was over-transmitted among NSCL/P group (P = 0.0086, OR_transmission = 1.36, 95%CI: 1.08–1.72). Parent-of-origin effect analysis revealed a paternal special over-transmission of allele A at rs708260 in NSCL/P group (P = 0.0079). Haplotype AC of rs7078160-rs4752028 was significant over-transmitted in the NSCL/P group.ConclusionsOur study firstly confirmed that allele A at rs7078160 at VAX1 gene was a risk factor for NSCL/P in Western Han Chinese population.
