Interferon Regulatory Factor 6 (IRF6) and TWIST1 are transcription factors necessary for craniofacial development. Human genetic studies showed that mutations in IRF6 lead to cleft lip and palate and mandibular abnormalities. In the mouse, we found that loss of Irf6 causes craniosynostosis and mandibular hypoplasia. Similarly, mutations in TWIST1 cause craniosynostosis, mandibular hypoplasia and cleft palate. Based on this phenotypic overlap, we asked if Irf6 and Twist1 interact genetically during craniofacial formation...

Primary cilia are nearly ubiquitous, cellular projections that function to transduce molecular signals during development. Loss of functional primary cilia has a particularly profound effect on the developing craniofacial complex, causing several anomalies including craniosynostosis, micrognathia, midfacial dysplasia, cleft lip/palate and oral/dental defects. Development of the craniofacial complex is an intricate process that requires interactions between several different tissues including neural crest cells, neuroectoderm and surface ectoderm...

3MC syndrome is an autosomal recessive heterogeneous disorder with features linked to developmental abnormalities. The main features include facial dysmorphism, craniosynostosis and cleft lip/palate; skeletal structures derived from cranial neural crest cells (cNCC). We previously reported that lectin complement pathway genes COLEC11 and MASP1/3 are mutated in 3MC syndrome patients. Here we define a new gene, COLEC10, also mutated in 3MC families and present novel mutations in COLEC11 and MASP1/3 genes in a further five families...

INTRODUCTION: Craniofacial surgeons treat patients with diverse craniofacial conditions (CFCs). Yet, little is known about the health-related quality of life (HRQoL) impact of diverse CFCs. Currently, there are no suitable instruments that measure the HRQoL of patients with diverse CFCs from the perspective of children and parents. The objective of this study was to develop the items and support the content validity of a comprehensive patient and parent-reported outcomes measure. METHODS: An iterative process consisting of a systematic literature review, expert opinion and in-depth interviews with patients and parents of patients with diverse CFCs was used...

Mechanical load influences bone structure and mass. Arguing the importance of load-transduction, we investigated the mechanisms inducing bone formation using an elastomeric substrate. We characterized Poly (glycerol sebacate) (PGS) in vitro for its mechanical properties, compatibility with osteoprogenitor cells regarding adhesion, proliferation, differentiation under compression versus static cultures and in vivo for the regeneration of a rabbit ulna critical size defect. The load-transducing properties of PGS were compared in vitro to a stiffer poly lactic-co-glycolic-acid (PLA/PGA) scaffold of similar porosity and interconnectivity...

Craniofacial malformations include a variety of anomalies, including cleft lip with or without cleft palate, craniosynostosis, microtia, and hemifacial microsomia. All of these anomalies can be either isolated or part of a defined genetic syndrome. A clinical geneticist or genetic counselor should be a member of the craniofacial team to help determine which patients have isolated anomalies and which are likely to have a syndrome. They would then arrange for the appropriate genetic testing to confirm the diagnosis of the specific syndrome...

The primary cilium is a ubiquitous, microtubule-based organelle that cells utilize to transduce molecular signals. Ciliopathies are a group of diseases that are caused by a disruption in the structure or function of the primary cilium. Over 30% of all ciliopathies are primarily defined by their craniofacial phenotypes, which typically include midfacial defects, cleft lip/palate, micrognathia, aglossia, and craniosynostosis. The frequency and severity of craniofacial phenotypes in ciliopathies emphasizes the importance of the cilium during development of the craniofacial complex...

BACKGROUND: Treatment for patients with diverse craniofacial conditions is complex and long-term. Craniofacial conditions profoundly influence health-related quality of life, and patient- and parent-reported outcomes provide a critical and complementary perspective on the multidisciplinary treatment of patients. However, little is known regarding the health-related quality of life among children with diverse craniofacial conditions. The purpose of this study was to systematically review the literature regarding patient- and parent-reported outcomes measures for patients with diverse craniofacial conditions...

OBJECTIVE:   Tinagl1 has a weak genetic association with craniosynostosis, but its functions in cartilage and bone development are unknown. Knockdown of Tinagl1 in zebrafish embryos allowed an initial characterization of its potential effects on craniofacial cartilage development and a test of whether these effects could involve Wnt signaling. RESULTS:   Tinagl1 knockdown resulted in dose-dependent reductions and defects in ventral pharyngeal arch cartilages as well as the ethmoid plate, a zebrafish correlate to the palate...

INTRODUCTION: Since the initiation of the "Back to Sleep Campaign" by the American Academy of Pediatrics in 1992, the incidence of referrals for positional plagiocephaly has increased by 600%. Although patients with positional plagiocephaly rarely require operative intervention, they often do require treatment with cranial molding helmets or positioning changes. The increased volume of patients makes the task of separating cases of craniosynostosis from positional head shape problems more difficult...

Development of the human skull and face is a highly orchestrated and complex three-dimensional morphogenetic process, involving hundreds of genes controlling the coordinated patterning, proliferation and differentiation of tissues having multiple embryological origins. Craniofacial malformations that occur because of abnormal development (including cleft lip and/or palate, craniosynostosis and facial dysostoses), comprise over one-third of all congenital birth defects. High-throughput sequencing has recently led to the identification of many new causative disease genes and functional studies have clarified their mechanisms of action...

Msx1 and Msx2 were revealed to be candidate genes for some craniofacial deformities, such as cleft lip with/without cleft palate (CL/P) and craniosynostosis. Many other genes were demonstrated to have a cross-talk with MSX genes in causing these defects. However, there is no systematic evaluation for these MSX gene-related factors. In this study, we performed systematic bioinformatic analysis for MSX genes by combining using GeneDecks, DAVID, and STRING database, and the results showed that there were numerous genes related to MSX genes, such as Irf6, TP63, Dlx2, Dlx5, Pax3, Pax9, Bmp4, Tgf-beta2, and Tgf-beta3 that have been demonstrated to be involved in CL/P, and Fgfr2, Fgfr1, Fgfr3, and Twist1 that were involved in craniosynostosis...

BACKGROUND: Case reports suggest that long-term, high-dose fluconazole treatment for severe fungal infections during pregnancy causes a pattern of birth defects. It is unclear whether commonly used lower doses increase the risk of specific birth defects. METHODS: In a registry-based cohort of liveborn infants in Denmark, we evaluated first-trimester oral fluconazole exposure and the risk of birth defects overall and of birth defects previously linked to azole antifungal agents...

The fibroblast growth factor (FGF) signalling pathway is critically involved in several aspects of craniofacial development, including formation of the lip and the palate. FGF receptors are activated by extracellular FGF ligands in order to regulate cellular processes such as migration and morphogenesis through instruction of specific target gene expression. A key factor in the development of orofacial structures is the interaction between mesodermal- and neural crest-derived mesenchyme and ecto- and endodermal-derived epithelium...

3MC syndrome has been proposed as a unifying term encompassing the overlapping Carnevale, Mingarelli, Malpuech and Michels syndromes. These rare autosomal recessive disorders exhibit a spectrum of developmental features, including characteristic facial dysmorphism, cleft lip and/or palate, craniosynostosis, learning disability and genital, limb and vesicorenal anomalies. Here we studied 11 families with 3MC syndrome and identified two mutated genes, COLEC11 and MASP1, both of which encode proteins in the lectin complement pathway (collectin kidney 1 (CL-K1) and MASP-1 and MASP-3, respectively)...

Many advances in health care are built on the evolution of technology. An entirely new patient has emerged in fetal medicine, with these advances in prenatal imaging allowing one to see and diagnose disease not previously appreciated. Clinicians can better plan for the delivery of the neonate, with identified anomalies being optimally managed and the impact on the neonate's health minimized. The oral and maxillofacial surgeon offers expertise in the management of craniomaxillofacial anomalies, including congenital tumors, facial clefts, craniosynostosis, micrognathia, and other congenital abnormalities...
