Testing Reported Associations of Gene Variants with Non-Syndromic Orofacial Clefts in the Polish Population. Biomedicines 2024; 12:1700. [PMID: 39200165 PMCID: PMC11351639 DOI: 10.3390/biomedicines12081700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2024] [Revised: 07/27/2024] [Accepted: 07/30/2024] [Indexed: 09/02/2024] Open
Abstract
Orofacial clefts (OFCs) are the second most common birth defect worldwide. The etiology of OFCs involves complex interactions between genetics and environment. Advances in genomic technologies have identified gene variants associated with OFCs. This study aimed to investigate whether selected SNPs in the MYH9, MTHFR, MAFB, and SUMO1 genes influence the occurrence of non-syndromic OFCs in the Polish population. The study included 209 individuals with non-syndromic OFCs and 418 healthy controls. Saliva and umbilical cord blood samples were collected for DNA extraction. Four SNPs in the MYH9, MTHFR, MAFB, and SUMO1 genes were genotyped using real-time PCR-based TaqMan assays. Statistical analysis was performed using logistic regression to assess the association between SNPs and OFCs. A significant association was found between the rs7078 CC polymorphism and OFCs (OR = 3.22, CI 1.68-6.17, p < 0.001). No significant associations were identified for the rs1081131, rs13041247, and rs3769817 polymorphisms. The research indicates that the rs7078 polymorphism significantly influences the occurrence of orofacial cleft palate in the Polish population, whereas the rs3769817, rs1801131, and rs13041247 SNPs do not show such a correlation.

J Dent Res Dent Clin Dent Prospects 2023; 17:149-153. [PMID: 38023796 PMCID: PMC10676531 DOI: 10.34172/joddd.2023.40640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 09/09/2023] [Indexed: 12/01/2023] Open
Abstract
Background Cleft lip/palate (CL/P) is a prevalent congenital disorder. Matrix metalloproteinases (MMPs) play a role in palatogenesis and have been proposed to be associated with nonsyndromic CL/P development. This study aimed to examine the association of MMP2 (rs243866) and MMP9 (rs3918242) gene polymorphism with nonsyndromic CL/P in an Iranian population. Methods Blood samples were collected from 120 nonsyndromic CL/P patients and 140 healthy newborns in this case-control study. DNA extraction was performed by the salting-out method, and the samples underwent polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP), using Pag and SphI enzymes, for genotyping MMP2 and MMP9 gene polymorphisms. Statistical analysis was performed with SPSS 11.5. Univariate and multivariate logistic regression models were used to calculate the odds ratios and 95% confidence intervals (CIs). The level of statistical significance was set at P<0.05. Results No significant association was found between MMP2 gene polymorphism and nonsyndromic CL/P. However, the MMP9 gene polymorphism had a significant association with nonsyndromic CL/P, with a higher prevalence of the T allele and TT genotype in the case group than the control group. Conclusion This study indicated a potential link between MMP9 gene polymorphism and nonsyndromic CL/P in an Iranian population. Future investigations with greater sample diversity and larger sample sizes are required to obtain more comprehensive and robust evidence. In-depth analyses and studies involving different ethnic groups can further enhance our understanding of the genetic underpinnings of CL/P.

A Comprehensive Genetic Analysis of Slovenian Families with Multiple Cases of Orofacial Clefts Reveals Novel Variants in the Genes IRF6, GRHL3, and TBX22. Int J Mol Sci 2023; 24:ijms24054262. [PMID: 36901693 PMCID: PMC10002089 DOI: 10.3390/ijms24054262] [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: 11/25/2022] [Revised: 01/13/2023] [Accepted: 02/15/2023] [Indexed: 02/23/2023] Open
Abstract
Although the aetiology of non-syndromic orofacial clefts (nsOFCs) is usually multifactorial, syndromic OFCs (syOFCs) are often caused by single mutations in known genes. Some syndromes, e.g., Van der Woude syndrome (VWS1; VWS2) and X-linked cleft palate with or without ankyloglossia (CPX), show only minor clinical signs in addition to OFC and are sometimes difficult to differentiate from nsOFCs. We recruited 34 Slovenian multi-case families with apparent nsOFCs (isolated OFCs or OFCs with minor additional facial signs). First, we examined IRF6, GRHL3, and TBX22 by Sanger or whole exome sequencing to identify VWS and CPX families. Next, we examined 72 additional nsOFC genes in the remaining families. Variant validation and co-segregation analysis were performed for each identified variant using Sanger sequencing, real-time quantitative PCR and microarray-based comparative genomic hybridization. We identified six disease-causing variants (three novel) in IRF6, GRHL3, and TBX22 in 21% of families with apparent nsOFCs, suggesting that our sequencing approach is useful for distinguishing syOFCs from nsOFCs. The novel variants, a frameshift variant in exon 7 of IRF6, a splice-altering variant in GRHL3, and a deletion of the coding exons of TBX22, indicate VWS1, VWS2, and CPX, respectively. We also identified five rare variants in nsOFC genes in families without VWS or CPX, but they could not be conclusively linked to nsOFC.

Teng T, Teng CS, Kaartinen V, Bush JO. A unique form of collective epithelial migration is crucial for tissue fusion in the secondary palate and can overcome loss of epithelial apoptosis. Development 2022; 149:275520. [PMID: 35593401 PMCID: PMC9188751 DOI: 10.1242/dev.200181] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 04/11/2022] [Indexed: 11/20/2022]
Abstract
Tissue fusion frequently requires the removal of an epithelium that intervenes distinct primordia to form one continuous structure. In the mammalian secondary palate, a midline epithelial seam (MES) forms between two palatal shelves and must be removed to allow mesenchymal confluence. Abundant apoptosis and cell extrusion support their importance in MES removal. However, genetically disrupting the intrinsic apoptotic regulators BAX and BAK within the MES results in complete loss of cell death and cell extrusion, but successful removal of the MES. Novel static- and live-imaging approaches reveal that the MES is removed through streaming migration of epithelial trails and islands to reach the oral and nasal epithelial surfaces. Epithelial trail cells that express the basal epithelial marker ΔNp63 begin to express periderm markers, suggesting that migration is concomitant with differentiation. Live imaging reveals anisotropic actomyosin contractility within epithelial trails, and genetic ablation of actomyosin contractility results in dispersion of epithelial collectives and failure of normal MES migration. These findings demonstrate redundancy between cellular mechanisms of morphogenesis, and reveal a crucial and unique form of collective epithelial migration during tissue fusion. Summary: Multiple cellular processes mediate secondary palate fusion, including a unique form of streaming collective epithelial migration driven by pulsatile actomyosin contractility.

[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
Orofacial clefts (OFCs) are the most common congenital birth defects in humans and immediately recognized at birth. The etiology remains complex and poorly understood and seems to result from multiple genetic and environmental factors along with gene-environment interactions. It can be classified into syndromic (30%) and nonsyndromic (70%) clefts. Nonsyndromic OFCs include clefts without any additional physical or cognitive deficits. Recently, various genetic approaches, such as genome-wide association studies (GWAS), candidate gene association studies, and linkage analysis, have identified multiple genes involved in the etiology of OFCs. This article provides an insight into the multiple genes involved in the etiology of OFCs. Identification of specific genetic causes of clefts helps in a better understanding of the molecular pathogenesis of OFC. In the near future, it helps to provide a more accurate diagnosis, genetic counseling, personalized medicine for better clinical care, and prevention of OFCs.

Abstract
BACKGROUND Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a common congenital malformation in the world. Both environment and genetics are involved with the etiology of the disease. Genome-wide association studies have identified two single nucleotide polymorphisms (SNPs) at chromosome 20q12 to be associated with NSCL/P. The current study aimed to explore the association of the two SNPs at 20q12 with NSCL/P and different subtypes in a Southern Chinese Han cohort. METHODS A total of 430 NSCL/P patients and 451 controls were recruited in the current study. Two SNPs including rs17820943 and rs6072081 at 20q12 were genotyped in the study cohort using Taqman SNP genotyping analysis. Chi-Square test was used to compare allele and genotype frequencies of NSCL/P patients and control group. RESULTS Case-control analysis showed that the allele and genotype of rs17820943 and rs6072081 were significantly associated with NSCL/P (p < .01). Comparison between subtypes of NSCL/P and controls showed that frequencies of the G allele and GG genotype of rs6072081 (p = 4.52 × 10-4 and p = .001 respectively), and those of the T allele and TT genotype of rs17820943 (p = 6.7 × 10-5 and p = 1.71 × 10-4 respectively) were decreased in cleft lip and palate (CLP). No significant association of the two SNPs with cleft lip only (CLO) and cleft palate only (CPO) was found (p > .05). CONCLUSION These results showed that rs17820943 and rs6072081 at 20q12 were associated with NSCL/P, especially with the CLP subtype in a Southern Chinese Han cohort.

Abstract
BACKGROUND Craniofacial morphogenesis is the result of an intricate multistep network of tightly controlled spatial and temporal signalling that involves several molecules and transcription factors organized into highly coordinated pathways. Any alteration in even one step of this delicate process can lead to congenital malformations such as cleft palate. One of the first steps in embryonal orofacial development is the migration of cells from the neural crests to the branchial arches. Next, the cells have to proliferate, differentiate, move and connect to each other in order to correctly form the palate. Cell contraction, promoted by the interaction of non-muscle myosin II and actin A, is a crucial step in morphogenesis and is regulated by ROCK1 protein. METHODS A family-based association study was carried out in order to verify whether or not genetic variants of ROCK1 were associated with non-syndromic cleft palate (nsCP). Two cohorts from Italy and Iran, a total of 189 nsCP cases and their parents were enrolled. RESULTS The rs35996865-G allele was under-transmitted in cases of nsCP [P = .006, odds ratio (OR) = 0.63 (95% CI 0.45-0.88)]. CONCLUSION This investigation reveals for the first time data supporting a role for ROCK1 in nsCP aetiology.

Abstract
In this issue of ckj, Tabibzadeh et al. report one of the largest series of patients with MYH9 mutations and kidney disease. The cardinal manifestation of MYH9-related disease is thrombocytopenia with giant platelets. The population frequency of pathogenic MYH9 mutations may be at least 1 in 20 000. The literature abounds in misdiagnosed cases treated for idiopathic thrombocytopenic purpura with immune suppressants and even splenectomy. Additional manifestations include neurosensorial deafness and proteinuric and hematuric progressive kidney disease (at some point, it was called Alport syndrome with macrothrombocytopenia), leucocyte inclusions, cataracts and liver enzyme abnormalities, resulting in different names for different manifestation combinations (MATINS, May-Hegglin anomaly, Fechtner, Epstein and Sebastian syndromes, and deafness AD 17). The penetrance and severity of kidney disease are very variable, which may obscure the autosomal dominant inheritance. A correct diagnosis will both preclude unnecessary and potentially dangerous therapeutic interventions and allow genetic counselling and adequate treatment. Morphological erythrocyte, granulocyte and platelet abnormalities may allow the future development of high-throughput screening techniques adapted to clinical peripheral blood flow cytometers.

Abstract
BACKGROUND Orofacial clefts include cleft lip only (CLO), cleft palate only (CPO), and cleft lip with palate (CLP). Previously, we reported the expression profile of plasma microRNAs in CLO, CPO, and CLP, respectively. However, the interaction of each subtype remains poorly investigated. METHODS In this study, we integrated the expression profiles of plasma miRNAs in these 3 subtypes, and assessed the distinct and overlapping dysregulated miRNAs using Venn diagrams. Their respective target genes reported in the literature were further analyzed using pathway analysis. RESULTS AND CONCLUSION The results showed that distinct or overlapping signaling pathways were involved in CLO, CPO, and CLP. The common key gene targets reflected functional relationships to the Wnt, Notch, TGF-beta, and Hedgehog signaling pathways. Further studies should examine the mechanism of the potential target genes, which may provide new avenues for future clinical prevention and therapy.

Abstract
Plasma microRNAs (miRNAs) have recently emerged as a new class of regulatory molecules that influence many biological functions. However, the expression profile of plasma microRNAs in nonsyndromic cleft palate (NSCP) or nonsyndromic cleft lip with cleft palate (NSCLP) remains poorly investigated. In this study, we used Agilent human miRNA microarray chips to monitor miRNA levels in three NSCP plasma samples (mixed as the CP group), three NSCLP plasma samples (mixed as the CLP group) and three normal plasma samples (mixed as the Control group). Six selected plasma miRNAs were validated in samples from an additional 16 CP, 33 CLP and 8 healthy children using qRT-PCR. Using Venn diagrams, distinct and overlapping dysregulated miRNAs were identified. Their respective target genes were further assessed using gene ontology and pathway analysis. The results show that distinct or overlapping biological processes and signalling pathways were involved in CP and CLP. Our study showed that the common key gene targets reflected functional relationships to the Notch, Wnt, phosphatidylinositol and Hedgehog signalling pathways. Further studies should examine the mechanism of the potential target genes, which may provide new avenues for future clinical prevention and therapy.

Abstract
Nonsyndromic orofacial clefts (NSOCs) are congenital newborn malformations. Myosin heavy chain 9 ( MYH9) is a candidate gene of NSOCs. To investigate the associations between single-nucleotide polymorphisms (SNPs) of MYH9 and NSOC susceptibility, a 2-stage case-control study was designed and 4 potentially functional SNPs of MYH9 (rs12107, rs2269529, rs9619601, rs5756130) were selected and genotyped by iPLEX Sequenom MassARRAY and TaqMan assay in the first stage (599 NSOC cases and 590 controls). The significant SNPs in the first stage were replicated in the second stage (676 NSOC cases and 705 controls) by TaqMan assay. Reverse transcription polymerase chain reaction, cell transfection, and luciferase assay were performed accordingly to explore their functionality. In stage I, rs12107 was nominally associated with NSOCs, whereas rs2269529 showed a significant association (rs12107: Phet = 0.028; rs2269529: Phet = 0.001). In stage II, rs12107 was nominally associated with NSOCs, and rs2269529 showed a significant association (rs12107: Phom = 0.014; rs2269529: Phet = 0.006). In combined stages, these 2 SNPs gained significant associations (rs12107: Pdom = 0.004; rs2269529: Pdom = 4.4 × 10-5). In subphenotype analysis, these 2 SNPs were associated with cleft lip only (CLO) and cleft lip with palate (CLP), and rs2269529 was also associated with cleft palate only (CPO). Haplotype analysis revealed associations between rs12107-G/rs2269529-T and NSOC susceptibility ( P = 0.011). Combined analysis of rs12107 and rs2269529 indicated the risk of NSOCs increased with the number of risk alleles (rs12107-G and rs2269529-T, P for trend = 0.008). MYH9 SNP rs12107 AG + GG and rs2269529 CT + TT were associated with higher MYH9 expression in lip tissues compared with their corresponding wild-type homozygote. For rs12107, higher luciferase activities of G allele than A allele were observed in the luciferase assay. MYH9 was downregulated when transfecting its putative binding target miR-196b-3p into human embryo plate mesenchyme (HEPM) and C2C12 cell lines. For rs2269529, C > T contributed to increased MYH9 messenger RNA. In conclusion, rs12107 and rs2269529 were associated with the expression of MYH9 and contributed to the susceptibility of NSOCs.

The study of association between reduced folate carrier 1 ( RFC1) polymorphism and non-syndromic cleft lip/palate in Iranian population. ACTA ACUST UNITED AC 2017; 7:263-268. [PMID: 29435434 PMCID: PMC5801538 DOI: 10.15171/bi.2017.31] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2017] [Revised: 11/22/2017] [Accepted: 11/23/2017] [Indexed: 12/26/2022]
Abstract
Introduction: Cleft lip/palate is one of the most common congenital defects and is supposed to have multifactorial etiology, including a complex interaction between genetics and environment. Reduced folate carrier 1 (RFC1) gene takes part in folate transportation within the cells. In this study, the association of A80G polymorphism in the RFC1 gene with the non-syndromic cleft lip/palate (nsCL/P) was investigated in Iranian infants for the first time. Methods: In this case-control survey, 122 Iranian infants with nsCL/P and 164 healthy infants were investigated for RFC1 polymorphism by PCR and RFLP methods. The results were statistically compared with control group, odds ratios with 95% CI were estimated by univariate and multivariate logistic regression model and a P <0.05 was considered statistically significant. Results: The RFC1 G allele was significantly higher (P=0.001; OR=7, 95% CI: 4.7-10.2) in the cases (60.3%) compared with the controls (17.9%). Not only the RFC1 AG genotype was significantly higher (P<0.001; OR=44, 95% CI: 14.6-133) in cases (67.8%) than the controls (27.4%), but also GG genotype (P<0.001; OR=85, 95% CI: 20.5-352) was much higher in cases (26.4%) than the controls (4.3%). Conclusion: Our study indicated that the RFC1 (A80G) polymorphism was associated with the nsCL/P in Iranian population. Moreover, 80GG homozygosity was significant in the cases. The presence of G allele can be considered as a risk factor for the nsCL/P. Infants with the GG and AG genotypes were more prone to cleft lip/palate as compared to the AA ones. This finding emphasizes the role of RFC1 gene and the intracellular levels of folate.

Abstract
Cleft lip with or without palate (CLP) and isolated cleft palate (CP) are common human developmental malformations with a complex etiology that reflects a failure of normal facial development. VAX1 encodes a homeobox-containing transcription factor identified as a candidate gene for CLP in human populations, with targeted deletion in mice associated with multiple anomalies, including disruption of the visual apparatus and basal forebrain, lobar holoprosencephaly, and CP. We have investigated Vax1 function during murine palatogenesis but found no evidence for a direct role in this process. Vax1 is not expressed in the developing palate and mutant palatal shelves elevate above the tongue, demonstrating morphology and proliferation indices indistinguishable from wild type. However, mutant mice did have a large midline cavity originating from the embryonic forebrain situated beneath the floor of the hypothalamus and extending through the nasal cavity to expand this region and prevent approximation of the palatal shelves. Interestingly, despite strong expression of Vax1 in ectoderm of the medial nasal processes, the upper lip remained intact in mutant mice. We found further evidence of disrupted craniofacial morphology in Vax1 mutants, including truncation of the midface associated with reduced cell proliferation in forebrain neuroectoderm and frontonasal mesenchyme. Sonic hedgehog (Shh) signal transduction was downregulated in the mutant forebrain, consistent with a role for Vax1 in mediating transduction of this pathway. However, Shh was also reduced in this region, suggestive of a Shh-Vax1 feedback loop during early development of the forebrain and a likely mechanism for the underlying lobar holoprosencephaly. Despite significant associations between VAX1 and human forms of CLP, we find no evidence of a direct role for this transcription factor in development of this region in a mutant mouse model.
