Abstract
BACKGROUND Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a prevalent craniofacial birth defect on a global scale. A number of candidate genes have been identified as having an impact on NSCL/P. However, the association between interferon regulatory factor 6 (IRF6) polymorphisms and NSCL/P has yielded inconsistent results, prompting the need for a meta-analysis to obtain more accurate estimates. METHODS We conducted a thorough screening of all relevant articles published up until November 15, 2023, in online bibliographic databases. The statistical analysis of the collected data was performed using the Comprehensive Meta-Analysis (Version 4.0) software. RESULTS A total of 79 case-control studies, comprising 14,003 cases and 19,905 controls, were included in our analysis. The combined data indicated that the IRF6 rs642961 and rs2235371 polymorphisms were associated with an increased risk of NSCL/P in the overall population. However, no significant association was found between the rs2013162 and rs2235375 polymorphisms and the risk of NSCL/P in the overall population. Furthermore, subgroup analyses revealed significant correlations between the IRF6 rs642961, rs2235371, and rs2235375 polymorphisms and the risk of NSCL/P based on ethnic background and country of origin. Nevertheless, the rs2013162 polymorphism plays a protective role in Caucasians and mixed populations. CONCLUSIONS Our collective data indicates a significant association between the rs642961 and rs2235371 polymorphisms and the risk of NSCL/P in the overall population. The rs2235375 polymorphism could influence the susceptibility to NSCL/P based on ethnic background. Meanwhile, the rs2013162 polymorphism provides protective effects in Caucasian, mixed populations, and the Brazilian population.

Brazilian Multiethnic Association Study of Genetic Variant Interactions among FOS, CASP8, MMP2 and CRISPLD2 in the Risk of Nonsyndromic Cleft Lip with or without Cleft Palate. Dent J (Basel) 2022; 11:dj11010007. [PMID: 36661544 PMCID: PMC9857865 DOI: 10.3390/dj11010007] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 12/14/2022] [Accepted: 12/16/2022] [Indexed: 12/29/2022] Open
Abstract
Associations of CRISPLD2 (cysteine-rich secretory protein LCCL domain containing 2) and genes belonging to its activation pathway, including FOS (Fos proto-oncogene), CASP8 (caspase 8) and MMP2 (matrix metalloproteinase 2), with nonsyndromic orofacial cleft risk, have been reported, but the results are yet unclear. The aim of this study was to evaluate single nucleotide polymorphisms (SNPs) in FOS, CASP8 and MMP2 and to determine their SNP-SNP interactions with CRISPLD2 variants in the risk of nonsyndromic cleft lip with or without cleft palate (NSCL±P) in the Brazilian population. The SNPs rs1046117 (FOS), rs3769825 (CASP8) and rs243836 (MMP2) were genotyped using TaqMan allelic discrimination assays in a case-control sample containing 801 NSCL±P patients (233 nonsyndromic cleft lip only (NSCLO) and 568 nonsyndromic cleft lip and palate (NSCLP)) and 881 healthy controls via logistic regression analysis adjusted for the effects of sex and genomic ancestry proportions with a multiple comparison p value set at ≤0.01. SNP-SNP interactions with rs1546124, rs8061351, rs2326398 and rs4783099 in CRISPLD2 were performed with the model-based multifactor dimensionality reduction test complemented with a 1000 permutation-based strategy. Although the association between FOS rs1046117 and risk of NSCL±P reached only nominal p values, NSCLO risk was significantly higher in carriers of the FOS rs1046117 C allele (OR: 1.28, 95% CI: 1.10-1.64, p = 0.004), TC heterozygous genotype (OR: 1.59, 95% CI: 1.16-2.18, p = 0.003), and in the dominant model (OR: 1.50, 95% CI: 1.10-2.02, p = 0.007). Individually, no significant associations between cleft risk and the SNPs in CASP8 and MMP2 were observed. SNP-SNP interactions involving CRISPLD2 variants and rs1046117 (FOS), rs3769825 (CASP8) and rs243836 (MMP2) yielded several significant p values, mostly driven by FOS rs1046117 and CASP8 rs3769825 in NSCL±P, FOS rs1046117 in NSCLO and CRISPLD2 rs8061351 in NSCLP. Our study is the first in the Brazilian population to reveal the association of FOS rs1046117 with NSCLO risk, and to support that CRISPLD2, CASP8, FOS and MMP2 interactions may be related to the pathogenesis of this common craniofacial malformation.

Machado RA, Ayroza Rangel ALC, de Almeida Reis SR, Scariot R, Coletta RD, Martelli-Júnior H. Evaluation of genome-wide association signals for nonsyndromic cleft lip with or without cleft palate in a multiethnic Brazilian population. Arch Oral Biol 2022; 135:105372. [PMID: 35151029 DOI: 10.1016/j.archoralbio.2022.105372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 12/07/2021] [Accepted: 02/06/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To evaluate previous nonsyndromic cleft lip with or without cleft palate (NSCL±P) associated signals in 4p16.2, 8p11.23, 12q13.13, 12q13.2 and 17q21.32 in a multiethnic Brazilian cohort. DESIGN The single nucleotide polymorphisms (SNPs) rs34246903 in 4p16.2, rs13317 in 8p11.23 (FGFR1, fibroblast growth factor receptor 1), rs3741442 in 12q13.13, rs705704 in 12q13.2 and rs4968247 in 17q21.32 were genotyped with TaqMan allelic discrimination assays in a case-control sample including 801 NSCL±P patients [233 nonsyndromic cleft lip (NSCLO) and 568 nonsyndromic cleft lip and palate (NSCLP)] and 881 healthy controls. Multiple logistic regression analyses, considering sex and genomic ancestry as covariates, were conducted, and the p value was adjusted with Bonferroni multiple correction testing (p ≤ 0.01). RESULTS Although several associations were identified, those that resisted the multiple correction testing involved the alleles and genotypes of rs34246903 and rs13317. The NSCLO group had a lower frequency of the minor C allele of rs34246903 compared to controls, giving an odds ratio (OR) of 0.74 [95% confidence interval (CI): 0.59-0.93, p = 0.01]. The rs34246903 CC genotype (homozygous) and the recessive model revealed significant protective associations with NSCLO, yielding ORs of 0.50 (95% CI: 0.29-0.85, p = 0.005) and 0.55 (95% CI: 0.33-0.93, p = 0.01) respectively. The presence of C variant allele of rs13317 (OR: 0.81, 95% CI: 0.69-0.96, p = 0.01) as well the TC genotype (OR: 0.77, 95% CI: 0.62-0.94, p = 0.01) and the dominant model (OR: 0.77, 95% CI: 0.63-0.94, p = 0.009) showed significant associations with reduced risk of NSCL±P. CONCLUSION Our study is the first to support the association of rs34246903 (4p16.2) with NSCLO and rs13317 within FGFR1 with NSCL±P in the highly admixed Brazilian population. Further studies are needed to determine the functionality of those SNPs or to identify the causal markers in linkage disequilibrium with those susceptibility markers.

Polymorphisms of ATP-Binding Cassette, Sub-Family A, Member 4 (rs560426 and rs481931) and Non-Syndromic Cleft Lip/Palate: A Meta-Analysis. Life (Basel) 2021; 11:life11010058. [PMID: 33467554 PMCID: PMC7830788 DOI: 10.3390/life11010058] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Revised: 12/19/2020] [Accepted: 01/07/2021] [Indexed: 12/29/2022] Open
Abstract
Background: A number of genes are associated with the incidence of non-syndromic cleft lip/palate (NSCL/P). Studies have shown a significant association between polymorphisms of ATP-binding cassette, sub-family A, member 4 (ABCA4) with the risk of NSCL/P. The present meta-analysis assessed the association between ABCA4 polymorphisms (rs560426 and rs481931) and the NSCL/P risk by reviewing case-control studies. Methods: Four databases (Scopus; Cochrane Library; Web of Science; and PubMed) were searched for articles published up to June 2020. The Review Manager 5.3 software was used to calculate the crude odds ratio (OR) and 95% confidence interval (CI). Both subgroup analyses for ethnicity and source of controls and a meta-regression related to publication year were conducted. Results: Of 94 retrieved studies, 12 were analyzed in this meta-analysis (2859 NSCL/P patients and 3792 controls for ABCA4 rs560426 polymorphism and 1333 NSCL/P patients and 1884 controls for ABCA4 rs481931 polymorphism). Overall, there was no significant association between both polymorphisms and the risk of NSCL/P. However, subgroup analysis demonstrated that there was a higher risk of NSCL/P for specific models: the allelic model (OR = 1.13; p = 0.03), the homozygote model (OR = 1.53; p = 0.04), and the recessive model (OR = 1.30; p = 0.03) in the Asian ethnicity for the rs560426 polymorphism. Conclusion: The findings confirmed that the NSCL/P risk was significantly associated with the G allele and GG genotype of rs560426 polymorphism but not for rs481931 polymorphism. There were no associations between both polymorphisms (rs560426 and rs481931) and the NSCL/P risk in those of European descent and the mixed ethnicities.

Abstract
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.

Abstract
Historically, the majority of statistical association methods have been designed assuming availability of SNP-level information. However, modern genetic and sequencing data present new challenges to access and sharing of genotype-phenotype datasets, including cost of management, difficulties in consolidation of records across research groups, etc. These issues make methods based on SNP-level summary statistics particularly appealing. The most common form of combining statistics is a sum of SNP-level squared scores, possibly weighted, as in burden tests for rare variants. The overall significance of the resulting statistic is evaluated using its distribution under the null hypothesis. Here, we demonstrate that this basic approach can be substantially improved by decorrelating scores prior to their addition, resulting in remarkable power gains in situations that are most commonly encountered in practice; namely, under heterogeneity of effect sizes and diversity between pairwise LD. In these situations, the power of the traditional test, based on the added squared scores, quickly reaches a ceiling, as the number of variants increases. Thus, the traditional approach does not benefit from information potentially contained in any additional SNPs, while our decorrelation by orthogonal transformation (DOT) method yields steady gain in power. We present theoretical and computational analyses of both approaches, and reveal causes behind sometimes dramatic difference in their respective powers. We showcase DOT by analyzing breast cancer and cleft lip data, in which our method strengthened levels of previously reported associations and implied the possibility of multiple new alleles that jointly confer disease risk.

Abstract
OBJECTIVE Nonsyndromic oral clefts are common birth defect with complex etiology. In the present study, we attempt to further validate the possible role for ABCA4 and ARHGAP29 in the susceptibility to nonsyndromic oral clefts. DESIGN We performed allelic transmission disequilibrium test analysis, on 10 eligible single nucleotide polymorphisms (SNPs) and SNP haplotypes using the Family-Based Association Test. PARTICIPANTS The study sample consisted of 334 case-parent trios of nonsyndromic oral clefts from Taiwanese population, separated into nonsyndromic cleft lip with or without cleft palate (NSCL/P) and nonsyndromic cleft palate only (NSCPO) groups. RESULTS We found only the SNP rs560426 within the ABCA4 gene showed strong association with NSCPO (P = .03498; Permuted P = .05382). No association between other 9 selected SNPs in ABCA4-ARHGAP29 region and the risk of nonsyndromic oral clefts was found. For the haplotype analyses, we found only haplotype T-C (rs570926 and rs3789431) in ABCA4 block 2 showed significant association with nonsyndromic NSCL/P in these Taiwanese trios. CONCLUSIONS We used a family-based analysis in 334 Taiwanese case-parent trios to validate the possible role for ABCA4 and ARHGAP29 in the susceptibility to nonsyndromic oral clefts. This study provides a new evidence for an association between the intron variant rs560426 within ABCA4 and nonsyndromic cleft palate which may contribute their regulatory role in craniofacial development.

Exploring GRHL3 polymorphisms and SNP-SNP interactions in the risk of non-syndromic oral clefts in the Brazilian population. Oral Dis 2019; 26:145-151. [PMID: 31564061 DOI: 10.1111/odi.13204] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 08/27/2019] [Accepted: 09/20/2019] [Indexed: 01/02/2023]
Abstract
OBJECTIVE To investigate the association of single-nucleotide polymorphisms (SNP) in grainyhead-like 3 (GRHL3) and to verify its possible interactions with others genes responsible for craniofacial development in the risk of non-syndromic oral cleft (NSOC). METHODS Applying TaqMan allelic discrimination assays, we evaluated GRHL3 SNPs (rs10903078, rs41268753, and rs4648975) in an ancestry-structured case-control sample composed of 1,127 Brazilian participants [272 non-syndromic cleft palate only (NSCPO), 242 non-syndromic cleft lip only (NSCLO), 319 non-syndromic cleft lip and palate (NSCLP), and 294 healthy controls]. Additionally, SNP-SNP interactions of GRHL3 and previously reported variants in FAM49A, FOXE1, NTN1, and VAX1 were verified in non-syndromic cleft lip with or without cleft palate (NSCL ± P). To eliminate false-positive associations, Bonferroni correction or 1,000 permutation method was applied. RESULTS The multiple logistic regression analysis showed that the CC genotype of rs10903078 (p = .03) and the haplotype C-C formed by the SNPs rs10903078 and rs41268753 (p = .04) were associated with NSCLO, but the p-values did not withstand Bonferroni correction. However, SNP-SNP test revealed significant interactions between GRHL3 SNPs and FAM49A (rs7552), FOXE1 (rs3758249), VAX1 (rs7078160 and rs751231), and NTN1 (rs9891446). CONCLUSIONS Our results confirm the importance of GRHL3 and its interactions with previously NSOC-associated genes, including FAM49A, FOXE1, NTN1, and VAX1, in the pathogenesis of NSOC in the Brazilian population.

Abstract
Background: Involvement of interferon regulatory factor 6 (IRF6) gene polymorphisms in nonsyndromic cleft palate (NSCP) risk remains controversial. This investigation was performed to evaluate the relationship between IRF6 gene polymorphisms and NSCP risk. Materials and Methods: Two hundred forty-one patients with NSCP (including 103 complete trio families) were recruited, and 242 unaffected individuals were included as controls. Polymorphisms for the IRF6 rs2235371, rs801619, rs642961, rs44844880, and rs8049367 loci were characterized in both groups. Furthermore, eligible studies were identified from the databases through June 1, 2017, and were included in a meta-analysis to enhance the robustness of our conclusions. Results: The IRF6 rs2235371 A allele and AA genotype in the case group were found at higher frequencies than in the control group (A allele: p < 0.0016; AA genotype: p < 0.0049). The IRF6 rs801619 AA genotype and G allele were associated with NSCP risk (G allele: p < 0.0061; AA genotype: p < 0.0195). At the IRF6 rs642961, rs44844880, and rs8049367 loci genotype and allele frequencies were not statistically different between the NSCP group and normal controls. In the meta-analysis, the IRF6 A/G gene polymorphism (rs2235371) and IRF6 A/G gene polymorphism (rs642961) were associated with NSCP risk in the general population, whereas the IRF6 A/C gene polymorphism (rs2013162) was not. Conclusion: The IRF6 A/G gene polymorphisms at rs2235371 and rs642961, but not the IRF6 A/C gene polymorphism rs2013162, were associated with NSCP risk.

Interactions between superoxide dismutase and paraoxonase polymorphic variants in nonsyndromic cleft lip with or without cleft palate in the Brazilian population. ENVIRONMENTAL AND MOLECULAR MUTAGENESIS 2019; 60:185-196.

Abstract
During development, oxidative stress is hypothesized to mediate embryotoxicity, which may be intensified by exposition to environmental factors and by genetic variations in the enzymes involved in protecting cells from these damaging effects, including superoxide dismutase (SOD) and paraoxonase (PON). The aim of this study was to evaluate the influence of single-nucleotide polymorphisms (SNP) in genes associated with the neutralization of oxidative stress (SOD and PON family members) in the risk of nonsyndromic oral cleft in the Brazilian population. Initially, we tested for association between 28 SNP in SOD1, SOD2, SOD3, PON1, PON2, and PON3 among 325 nonsyndromic cleft lip with or without cleft palate (NSCL±P) case-parent trios. Multiple logistic regression analyses were used to explore gene, GxG and GxE, involving factors that induce oxidative stress accumulation during pregnancy. Signals still significant after both Bonferroni correction and in permutation test were subsequently confirmed in an ancestry-structured case-control analysis with 722 NSCL±P and 866 controls from the same population. In the trio sample, transmission disequilibrium test (TDT) (allele and haplotype) and GxE analysis showed no significant associations, but multiple pairwise GxG interactions involving 10 SNP in PON1, PON2, and PON3 were detected and further examined in the case-control sample. The PON1 rs2237583 and PON2 rs17166879 yielded significant evidence of SNP-SNP interactions after adjustment for multiple tests (both Bonferroni correction and 10,000 permutation test). The C allele and the CT genotype of PON1 rs2237583 were associated with significant protective effects against NSCL±P, while rs3917490 showed a significant association only in the sample composed of patients displaying high African ancestry. Our results reveal associations between rs2237583 and rs3917490 in PON1 and GxG interactions containing rs2237583 and rs17166879 with the susceptibility of NSCL±P in the Brazilian population. Furthermore, this study underlines the recent tendency of taking into account potential GxG interactions to clarify the underlying mechanisms associated with the etiology of this common malformation.

Abstract
BACKGROUND Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is one of the most common craniofacial birth defects, and the etiology of NSCL/P involves both genetic and environmental factors. Genome-wide association study (GWAS) identified a novel susceptibility locus of ventral anterior homeobox 1 (VAX1) in patients with NSCL/P. However, the association of single nucleotide polymorphisms (SNPs) of VAX1 with NSCL/P is inconclusive due to the differences in the racial and ethnic populations. The aim of this study was to replicate the association between VAX1 and NSCL/P in a northern Chinese Han population. METHODS Our study included 186 patients with NSCL/P and 223 healthy individuals from northern China. Five SNPs (rs4752028, rs10787760, rs7078160, rs6585429, and rs1871345) on VAX1 were genotyped using the SNaPshot method. RESULTS Recessive genetic model analysis revealed that homozygous genotype CC of VAX1 rs4752028 was associated with an increased risk of NSCL/P (odds ratio = 1.89, 95% confidence interval = 1.12-3.19, P = 0.017), but the results were not significant after the Bonferroni correction for multiple comparisons. The allele and genotype frequencies of rs10787760, rs7078160, rs6585429, and rs1871345 and the allele frequencies of rs4752028 showed no significant differences between cases and controls. Haplotype and SNP-SNP interaction analyses did not detect any significant association of VAX1 with the occurrence of NSCL/P. CONCLUSION VAX1 rs4752028 was weakly associated with NSCL/P development in the studied northern Chinese Han population.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis of interferon regulatory factor 6 and 8q24 polymorphisms with nonsyndromic cleft lip with/without cleft palate (NSCL/P). METHODS Data extraction was independently performed by two reviewers. Genotypic effects of four polymorphisms from 31 studies were pooled separately by ethnicity using a mixed-effect logit model with accounting for heterogeneity. RESULTS For rs2235371, AA and GA carried, respectively, 51% (95% confidence interval [CI], 37%-61%) and 42% (95% CI, 32%-50%) lower risks of NSCL/P than GG genotypes in Asians, but these genotypes were not significant in Caucasians. For rs2013162, only AA was significant, that is, carried 0.65 (95% CI, 0.52-0.82) times lower odds than CC in Caucasians but not for Asians. For rs642961, AA and GA genotypes, respectively, carried 2.47 (95% CI, 1.41-4.35) and 1.40 (95% CI, 1.12-1.75) times higher odds in Asian, and 2.03 (95% CI, 1.52-2.71) and 1.58 (95% CI, 1.37-1.82) times higher odds in Caucasians compare with GG genotypes. For rs987525, AA and CA genotypes carried 2.27 (95% CI, 1.43-3.60) and 1.34 (95% CI, 1.02-1.77) times higher odds in Asian, and 5.25 (95% CI, 3.98-6.91) and 2.13 (95% CI-1.82, 2.49) times higher odds in Caucasians, and 1.42 (95% CI, 1.10-1.82) and 1.28 (95% CI, 1.09-1.50) times higher odds in mixed ethnicities compared with CC genotypes. These variant effects remained significant based on applying Bonferroni corrected-thresholds, except in the mixed ethnicity. CONCLUSION We show robust variant effects in NSCL/P. Considering them with other genes and risk factors might be useful to improve prediction of NSCL/P occurrence.

Abstract
BACKGROUND Variants in the cysteine-rich secretory protein LCCL domain containing 2 gene (CRISPLD2) and in the jumonji, AT-rich interaction domain 2 gene (JARID2) were previously shown to influence non-syndromic oral cleft susceptibility. Herein, we performed a case-control study to examine the potential association of single-nucleotide polymorphisms (SNPs) in CRISPLD2 and JARID2 with non-syndromic cleft lip and/or palate (NSCL/P) in the Brazilian population. Given the ethnicity-dependent genetic predisposition to NSCL/P, we performed a structured analysis taking into account the genomic ancestry variation of each individual. METHODS Four SNPs in CRISPLD2 (rs1546124, rs8061351, rs2326398, and rs4783099) and four in JARID2 (rs915344, rs2299043, rs2237138, and rs2076056), that were previously reported to be associated with NSCL/P, were genotyped in 785 Brazilian patients with NSCL/P (549 with cleft lip with or without cleft palate-NSCL ± P, and 236 with cleft palate only-NSCPO) and 693 unaffected Brazilian controls. Genomic ancestry was assessed with a set of 40 biallelic short insertion/deletion variants previously validated as ancestry informative markers of the Brazilian population. RESULTS After adjustment of ancestry variations, allelic analysis revealed marginal associations between the CRISPLD2 rs4783099 T allele and increased risk for NSCPO (OR: 1.31, 95% CI: 1.05-1.62, P = 0.01) and between JARID2 rs2237138 and decreased NSCL ± P risk (OR: 0.80, 95% CI: 0.67-0.97, P = 0.02). Haplotype analysis indicated a lack of association between JARID2 haplotypes and non-syndromic oral cleft risk. CONCLUSIONS Our results suggest that CRISPLD2 rs4783099 may represent a risk factor for NSCPO while JARID2 rs2237138 shows a protective effect against NSCL ± P in the Brazilian population.

Abstract
BACKGROUND Recent genome-wide association studies (GWAS) have reported multiple genetic risk loci for non-syndromic orofacial clefts (NSOFCs) in many populations. However, the contribution of these loci to NSOFC in India, which comprises one-fifth of the global population, is completely lacking. Our aim was to replicate the association of the SNPs located on 1p22 chromosomal loci (rs540026, rs481931) and 20q11.2 (rs13041247, rs11696257) in the aetiology of NSOFCs, in South Indian populations. METHODS The SNPs were genotyped by using KBiosciences KASPar SNP genotyping chemistry in 173 cases and 176 controls for NSOFCs in South India. To estimate the association between these SNPs and NSOFCs, chi-square test was adopted. Odds ratios (OR) with 95% confidence intervals (CI) were also calculated in order to assess the risk. RESULTS Single nucleotide polymorphisms located at chromosomal region 1p22 are not found to be associated with cleft lip with or without non-syndromic cleft palate (NSCL/P) and non-syndromic cleft palate only (NSCPO) at either the genotype or allele levels. Further, there is no LD observed between these variants. The polymorphic variants near 20q11.2 (rs13041247, rs11696257) are in complete linkage disequilibrium (LD) and are significantly associated with only NSCL/P in genotypic (p=0.013) and allelic models (p=0.029). In the genotypic model significance persisted even after Bonferroni correction (p<0.016). CONCLUSION These results suggest that 20q11.2 SNPs could play a contributory role in the pathophysiology and risk of NSCL/P, while the variations in 1p22 do not underlie the pathophysiology of NSOFCs in South Indian populations.

Abstract
OBJECTIVE To determine the association of single-nucleotide polymorphisms (SNPs) in genes related to craniofacial development, which were previously identified as susceptibility signals for nonsyndromic oral clefts, in Brazilians with nonsyndromic cleft lip and/or palate (NSCL/P). DESIGN The SNPs rs748044 (TNP1), rs1106514 (MSX1), rs28372960, rs15251 and rs2569062 (TCOF1), rs7829058 (FGFR1), rs1793949 (COL2A1), rs11653738 (WNT3), and rs242082 (TIMP3) were assessed in a family-based transmission disequilibrium test (TDT) and a structured case-control analysis based on the individual ancestry proportions. SETTING The SNPs were initially analyzed by TDT, and polymorphisms showing a trend toward excess transmission were subsequently studied in an independent case-control sample. PARTICIPANTS The study sample consisted of 189 case-parent trios of nonsyndromic cleft lip with or without cleft palate (NSCL±P), 107 case-parent trios of nonsyndromic cleft palate (NSCP), 318 isolated samples of NSCL±P, 189 isolated samples of NSCP, and 599 healthy controls. MAIN OUTCOME MEASURE Association of alleles with NSCL/P pathogenesis. RESULTS Preferential transmission of SNPs rs28372960 and rs7829058 in NSCL±P trios and rs11653738 in NSCP trios (P = .04) were observed, although the structured case-control analysis did not confirm these associations. The haplotype T-C-C formed by TCOF1 SNPs rs28372960, rs15251, and rs2569062 was more frequently transmitted from healthy parents to NSCL±P offspring, but the P value (P = .01) did not withstand Bonferroni correction for multiple tests. CONCLUSIONS With the modest associations, our results do not support the hypothesis that TNP1, MSX1, TCOF1, FGFR1, COL2A1, WNT3, and TIMP3 variants are risk factors for nonsyndromic oral clefts in the Brazilian population.

Abstract
BACKGROUND Although genome-wide association studies have identified several susceptibility loci for nonsyndromic cleft lip with or without cleft palate (NSCL/P) in populations around the world, the role of most loci is unknown in the highly heterogeneous Brazilian population. METHODS To determine the association of 7 markers that showed genome-wide significant association in Brazilians with NSCL/P, we conducted a structured association study conditioned upon the individual ancestry proportions to evaluate markers at 1p36 (rs742071), 2p21 (rs7590268), 3p11.1 (rs7632427), 8q21.3 (rs12543318), 13q31.1 (rs8001641), 15q22.2 (rs1873147), and 17q22 (rs227731) in 505 patients with NSCL/P and 594 healthy controls recruited from 2 different geographical regions of Brazil. The polymorphisms were genotyped by TaqMan 5'-exonuclease allelic discrimination assay, and each sample was independently typed for 40 biallelic short insertion/deletion markers to characterize the genomic ancestry. RESULTS After Bonferroni correction for multiple tests, significant associations with NSCL/P were observed for rs742071, rs1873147, and rs227731. However, the frequency of the risk alleles varied between the geographical regions, according to the proportions of European and African genomic ancestry. The group enriched by European ancestry showed significant association with rs227731 (p = 0.001), whereas the group with high African ancestry was significantly associated with rs1873147 polymorphism (p = 0.005). The significant association with rs742071 was only detected in the combined sample (p = 0.005). CONCLUSION The findings of the present study revealed the associations of 1p36 (rs742071), 15q22 (rs1873147), and 17p22 (rs227731) with NSCL/P in the Brazilian population, and further confirmed that the genetic heterogeneity of NSCL/P may be related to the different ethnic background of the affected individuals.

Abstract
BACKGROUND Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a common birth defect of complex etiology. Several genes have been implicated in the etiology of NSCL/P, although only a few have been replicated across datasets. METHODS ARHGAP29 was suggested as a candidate gene for NSCL/P as it is located in close proximity to ABCA4 (1p22), a gene previously identified in a genome-wide association study of NSCL/P. RESULTS Rare, potentially damaging, coding variants in ARHGAP29 were found in NSCL/P cases, and its expression was detected during murine craniofacial development. In this study, we investigated whether variations in ARHGAP29 were associated with NSCL/P in our family based dataset. Five single-nucleotide polymorphisms (SNPs) flanking and within ARHGAP29 were genotyped in our NSCL/P datasets consisting of simplex and multiplex families of non-Hispanic white (NHW, primarily European) and Hispanic ethnicities. Results showed strong association of three ARHGAP29 SNPs with NSCL/P in the NHW families. Two intronic SNPs (rs1541098 and rs3789688) showed strong association with NSCL/P in all NHW families (p = 0.0005 and p = 0.0002, respectively), and simplex NHW families (p = 0.003 for both SNPs). A SNP in the 3' untranslated region (rs1576593) also showed strong association with NSCL/P in all NHW families (p = 0.002), and the multiplex subset (p = 0.002). ARHGAP29 SNP haplotypes were also associated with NSCL/P. Evidence of gene-gene interaction was found between ARHGAP29 and additional cleft susceptibility genes. CONCLUSION This study further supports ARHGAP29 as a candidate gene for human NSCL/P in families of Caucasian descent.

Abstract
BACKGROUND Polymorphisms within the MTHFR (rs2274976) and MTHFD1 (rs2236225) genes were previously associated with maternal susceptibility for having an offspring with nonsyndromic cleft lip with or without cleft palate (NSCL/P) in the Brazilian population. However, as the genotypes of the patients with NSCL/P were not evaluated, it is not clear whether the effects are associated with maternal or offspring genotypes. The aim of this study was to evaluate the association of rs2274976 and rs2236225 in the pathogenesis of NSCL/P. METHODS By using the TaqMan 5'-exonuclease allelic discrimination assay, the present study genotyped the rs2274976 and rs2236225 polymorphisms in 147 case-parent trios, 181 isolated samples of NSCL/P and 478 healthy controls of the Brazilian population. Transmission disequilibrium test and structured case-control analysis based on the individual ancestry proportions were performed. RESULTS The transmission disequilibrium test showed a significant overtransmission of the rs2274976 A allele (p = 0.004), but no preferential parent-of-origin transmission was detected. The structured case-control analysis supported those findings, revealing that the minor A allele of rs2274976 was significantly more frequent in NSCL/P group compared with control group (p = 0.001), yielding an odds ratio of 3.46 (95% confidence interval, 2.05-5.85). No association of rs2236225 polymorphism with NSCL/P was observed in both transmission disequilibrium test and case-control analysis. CONCLUSION The results of the study revealed that the presence of the rs2274976 A allele is a risk marker for the development of NSCL/P in the Brazilian population.

Abstract
BACKGROUND Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is the most common orofacial birth defect with a wide range prevalence among different populations. Previous association studies with populations from Europe and Asia have identified putative susceptibility markers for NSCL/P in fibroblast growth factor 12 (FGF12), vinculin (VCL), connexin 43 (CX43) and in a region close to the ventral anterior homeobox 1 (VAX1) gene. However, there have thus far been no studies of these markers in NSCL/P Brazilian patients, and as the genetic ancestry of the Brazilian population is highly varied, the predisposition to those disease markers can be different. METHODS Herein we conducted a structured association study conditioned on the individual ancestry proportions to determine the role of 16 polymorphic markers within those genes in 300 patients with NSCL/P and 385 unaffected controls. RESULTS None of the alleles and genotypes showed association with NSCL/P, though there was a significant association of the haplotype formed by VAX1 rs10787760, rs6585429 and rs1871345 polymorphisms with NSCL/P that did not persist Bonferroni correction for multiple tests. CONCLUSIONS Our results are consistent with a lack of involvement of FGF12, VCL and CX43 variants with NSCL/P pathogenesis in Brazilian patients. Furthermore, the higher frequency of a haplotype of VAX1 with NSCL/P patients suggests a low penetrant gene for oral cleft, and warrants further studies.
