Lack of association between IRF6 polymorphisms (rs2235371 and rs642961) and non‐syndromic cleft lip and/or palate in a Brazilian population

Oral Diseases (2010) 16 , 193–197 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.     

IRF6 gene variants in Central European patients with non‐syndromic cleft lip with or without cleft palate

Variants in the interferon regulatory factor 6 (IRF6) gene have repeatedly been associated with non‐syndromic cleft lip with or without cleft palate (NSCL/P). A recent study has suggested that the functionally relevant variant rs642961 is the underlying cause of the observed associations. We genotyped rs642961 in our Central European case–control sample of 460 NSCL/P patients and 952 controls. In order to investigate whether other IRF6 variants contribute independently to the etiology of NSCL/P, we also genotyped the non‐synonymous coding variant V274I (rs2235371) and five IRF6‐haplotype tagging single nucleotide polymorphisms (SNPs). A highly significant result was observed for rs642961 (P = 1.44 × 10^?6) in our sample. The odds ratio was 1.75 [95% confidence interval (CI): 1.38–2.22] for the heterozygous genotype and 1.94 (95% CI: 1.21–3.10) for the homozygous genotype, values that are similar to those reported in a previously published family‐based study. Our results thus confirm the involvement of the IRF6 variant, rs642961, in the etiology of NSCL/P in the Central European population. We also found evidence suggestive of an independent protective effect of the coding variant V274I. In order to understand fully the genetic architecture of the IRF6 locus, it will be necessary to conduct additional SNP‐based and resequencing studies using large samples of patients.     

Interferon regulatory factor 6 variants affect nasolabial morphology in East Asian populations

ObjectiveThe interferon regulatory factor 6 gene (IRF6) is one of the most conspicuous genes among a large number of candidate risk genes for non-syndromic cleft lip with or without cleft palate, which is considered to be a multifactorial defect. Variants of IRF6 are also suggested to affect normal craniofacial variations, especially in the area of the nose and the upper lip. In the present study, we used lateral cephalograms to establish the relationship between IRF6 and sagittal nasolabial morphology in healthy East Asian subjects.DesignGenomic DNA was extracted from 215 Japanese and 226 Korean individuals, and genotyped for five IRF6 single nucleotide polymorphisms (SNPs): rs17389541, rs642961, rs2013162, rs2235371, and rs7802. These SNPs were tested by multiple regression analyses for their association with craniofacial measurements obtained from lateral cephalometrics.ResultsWe detected a significant association between the derived variants, rs2013162 and rs2235371 and the distances between a facial bone plane indicated by distance from Nasion and Point A (NA plane) to soft tissue landmarks; the Subalare (NA-Sbal) and the Subnasale (NA-Sn) in the sagittal plane.ConclusionOur results indicate that IRF6 variants play an important role in the normal range of variation in nasolabial soft-tissue morphology.

Association study of single nucleotide polymorphisms of MAFB with non-syndromic cleft lip with or without cleft palate in a population in Heilongjiang Province,northern China

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^® Multiplex System for SNP genotyping, Life Technologies Ltd, Paisley, UK). We found that rs6065259 was the most important single nucleotide polymorphism in MAFB (OR_6065259-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.

目的 探讨干扰素调节因子6(interferon regulatory factor 6, IRF6) 在非综合征性唇腭裂(non-sydromic cleft lip and/or cleft palate,NSCL/P)患者中的突变情况。方法：收集119例NSCL/P患者及288名健康人对照样本的外周血血样并提取DNA。在IRF6基因的全部外显子分别设计引物,PCR扩增其序列,通过测序找出IRF6基因突变,并将这些突变在对照样本中进行验证。结果：共发现5种在正常人中没有的突变,其中4种是新发现的突变。结论：IRF6基因突变在中国人群中参与了非综合征唇腭裂疾病的发生。     

Familial non-syndromic cleft lip and palate--analysis of the IRF6 gene and clinical phenotypes

The aim of this study was to characterize Swedish families with non-syndromic cleft lip and/or palate (NSCL/P) for mutations or other sequence variants in the interferon regulatory factor 6 (IRF6) gene, as well as to describe their cleft phenotypes and hypodontia. Seventeen Swedish families with at least two family members with NSCL/P were identified and clinically evaluated. Extracted DNA from blood samples was used for IRF6 mutation screening. Exonic fragments of the IRF6 gene were sequenced and chromatograms were inspected. Statistical analysis was undertaken with marker- and haplotype association tests. No disease-associated IRF6 mutation could be determined in the families analyzed. One new and seven known single nucleotide polymorphisms (SNPs) were detected. The A allele of SNP rs861019 in exon 2 and the G allele of SNP rs7552506 in intron 3 showed association with cleft lip and palate (CLP; odds ratios of 3.1 and 5.45, respectively). Hypodontia was observed more commonly in individuals affected with CL/P as compared with family members without a cleft (P < 0.01). The hypodontia most often affected the cleft area, possibly representing a secondary effect. The distribution of cleft phenotypes in 15 of the 17 families with NSCL/P differed from the mixed cleft types seen in Van der Woude syndrome (VWS), in that CLP did not occur together with an isolated cleft palate within the same family. It was concluded that mutations of the IRF6 gene are not a common cause for cleft predisposition in Swedish NSCL/P families.

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.
