[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.

Evaluation of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in human cases with orofacial clefts: A systematic review. Int Orthod 2023; 21:100781. [PMID: 37301105 DOI: 10.1016/j.ortho.2023.100781] [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: 04/01/2023] [Revised: 05/01/2023] [Accepted: 05/02/2023] [Indexed: 06/12/2023]
Abstract
INTRODUCTION The interaction between several cell populations or many genes and the coordination of multiple signal transmission pathways can lead to defects such as orofacial clefts (OFCs). Herein, a systematic review was designed to evaluate a group of important biomarkers (matrix metalloproteinases [MMPs] and tissue inhibitors of metalloproteinases [TIMPs]) in human cases with OFCs. MATERIAL AND METHODS Four databases including PubMed, Scopus, Web of Science, and Cochrane Library databases were searched until March 10, 2023, without any restriction. STRING, the protein-protein interaction (PPI) network software, was applied to investigate the functional interactions among the examined genes. The effect sizes including odds ratio (OR) dealing with a 95% confidence interval (CI), were extracted by the Comprehensive Meta-Analysis version 2.0 (CMA 2.0) software. RESULTS Thirty-one articles were entered into the systematic review that four articles were analyzed in the meta-analysis. Single studies reported that several polymorphisms of MMPs (rs243865, rs9923304, rs17576, rs6094237, rs7119194, and rs7188573); and TIMPs (rs8179096, rs7502916, rs4789936, rs6501266, rs7211674, rs7212662, and rs242082) had an association with OFC risk. There was no significant difference for MMP-3 rs3025058 polymorphism in allelic (OR: 0.832; P=0.490), dominant (OR: 1.177; P=0.873), and recessive (OR: 0.363; P=0.433) models and MMP-9 rs17576 polymorphism in an allelic model (OR: 0.885; P=0.107) between the OFC cases and the controls. Based on immunohistochemistry reports, three MMPs (MMP-2, MMP-8, and MMP-9) and TIMP-2 had significant correlations with several other biomarkers in OFC cases. CONCLUSIONS MMPs and TIMPs can impact the tissue and cells affected by OFCs and the process of apoptosis. The interaction between some biomarkers with MMPs and TIMPs (e.g., TGFb1) in OFCs can be interesting for future research.

Abstract
OBJECTIVES This study investigated the association of MSX1 gene variants rs3821949 and rs12532 with nonsyndromic cleft lip and/or palate (NSCL/P) in the Pakistani population. DESIGN Comparative cross-sectional study.Setting: Multicenter of CL/P malformation.Patients/Participants: Unrelated Non-Syndromic cleft Lip/Palate patients and healthy controls were enrolled. METHODS One hundred (n = 100) subjects with NSCL/P and n = 50 unrelated healthy controls were enrolled in a multicenter comparative cross-sectional study. A tetra amplification refractory mutation system (ARMS) polymerase chain reaction (PCR) was performed to analyze MSXI gene single nucleotide variants (SNVs). RESULTS Among 100 NSCL/P subjects, the majority were males (56%; male: female = 1.27: 1). Most of the cases (74%) had cleft lip and palate (CLP) compared to isolated clefts. Genotyping of MSX1 gene variant rs3821949 showed an increased risk for NSCL/P in various genetic models (P < 0.0001), and the A allele exhibited a more than 4-fold increased risk among cases (OR = 4.22: 95% CI = 2.16-8.22; P < 0.0001). Our investigation found no significant difference between the rs12532 variation and NSCL/P. CONCLUSION Our study findings suggest that MSX1 gene variants may increase predisposition to NSCL/P in the Pakistani population. Further studies comprising large samples are required to identify the genetic aetiology of NSCL/P among our people.

A Synonymous Exonic Splice Silencer Variant in IRF6 as a Novel and Cryptic Cause of Non-Syndromic Cleft Lip and Palate. Genes (Basel) 2020; 11:genes11080903. [PMID: 32784565 PMCID: PMC7465030 DOI: 10.3390/genes11080903] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/28/2020] [Accepted: 08/04/2020] [Indexed: 12/31/2022] Open
Abstract
Missense, nonsense, splice site and regulatory region variants in interferon regulatory factor 6 (IRF6) have been shown to contribute to both syndromic and non-syndromic forms of cleft lip and/or palate (CL/P). We report the diagnostic evaluation of a complex multigeneration family of Honduran ancestry with a pedigree structure consistent with autosomal-dominant inheritance with both incomplete penetrance and variable expressivity. The proband's grandmother bore children with two partners and CL/P segregates on both sides of each lineage. Through whole-exome sequencing of five members of the family, we identified a single shared synonymous variant, located in the middle of exon 7 of IRF6 (p.Ser307Ser; g.209963979 G>A; c.921C>T). The variant was shown to segregate in the seven affected individuals and through three unaffected obligate carriers, spanning both sides of this pedigree. This variant is very rare, only being found in three (all of Latino ancestry) of 251,352 alleles in the gnomAD database. While the variant did not create a splice acceptor/donor site, in silico analysis predicted it to impact an exonic splice silencer element and the binding of major splice regulatory factors. In vitro splice assays supported this by revealing multiple abnormal splicing events, estimated to impact >60% of allelic transcripts. Sequencing of the alternate splice products demonstrated the unmasking of a cryptic splice site six nucleotides 5' of the variant, as well as variable utilization of cryptic splice sites in intron 6. The ectopic expression of different splice regulatory proteins altered the proportion of abnormal splicing events seen in the splice assay, although the alteration was dependent on the splice factor. Importantly, each alternatively spliced mRNA is predicted to result in a frame shift and prematurely truncated IRF6 protein. This is the first study to identify a synonymous variant as a likely cause of NS-CL/P and highlights the care that should be taken by laboratories when considering and interpreting variants.

Abstract
Craniofacial development involves several complex tissue movements including several fusion processes to form the frontonasal and maxillary structures, including the upper lip and palate. Each of these movements are controlled by many different factors that are tightly regulated by several integral morphogenetic signaling pathways. Subject to both genetic and environmental influences, interruption at nearly any stage can disrupt lip, nasal, or palate fusion and result in a cleft. Here, we discuss many of the genetic risk factors that may contribute to the presentation of orofacial clefts in patients, and several of the key signaling pathways and underlying cellular mechanisms that control lip and palate formation, as identified primarily through investigating equivalent processes in animal models, are examined.

Orthod Craniofac Res 2020; 23:151-159. [PMID: 31944555 DOI: 10.1111/ocr.12366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 01/09/2020] [Accepted: 01/10/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The purpose of the present work was to investigate the association between forkhead box E1 (FOXE1) and the risk of non-syndromic cleft lip with or without cleft palate (NSCL/P). MATERIALS AND METHODS Relevant studies were searched in several professional databases up to 31 July 2019. The pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using a fixed-effect model or a random-effect model to analyse the relationship between FOXE1 polymorphisms and NSCL/P. RESULTS A total of four single nucleotide polymorphisms (SNPs), including rs3758249, rs4460498, rs1443434 and rs10217225, were analysed. The overall findings showed that FOXE1 rs4460498 was statistically associated with NSCL/P (including cleft lip with or without cleft palate (CL/P) and cleft palate only (CPO)). Genotypes CC and CT of rs4460498 were significantly more closely correlated with NSCL/P (including CL/P and CPO) than genotype TT (NSCL/P: TT vs CC, OR = 0.630, P = .000; TT vs TC + CC, OR = 0.775, P = .020; CL/P: TT vs CC, OR = 0.664, P = .000; TT vs TC + CC, OR = 0.738, P = .006. CPO: TT vs CC, OR = 0.761, P = .027; TT vs TC + CC, OR = 0.792, P = .045). For rs10217225, only the TT genotype might have contributed to the elevated risk of CL/P (TT vs CC OR = 2.236, P = .000). The other FOXE1 polymorphisms were not associated with NSCLP, CL/P or CPO. CONCLUSION The meta-analysis provided confirmation that the polymorphism of FOXE1 rs10217225 was correlated with an increased risk of CL/P, and the polymorphism of FOXE1 rs4460498 was a protective factor for NSCL/P, including CLP and CPO.
