INTRODUCTION: Cleft lip and palate, the most common developmental deformity, is seen worldwide and the etiology involves a combination of genetic and environmental factors. The purpose of this study was to determine the maternal risk factors associated with the development of cleft lip and cleft palate. MATERIALS AND METHODS: We conducted a case control study at the Women's Hospital in Culiacan, Mexico. Medical records were analyzed, including patients who delivered babies with and without cleft lip and cleft palate from January 2010 to December 2015...

Secondary palatogenesis occurs when the bilateral palatal shelves (PS), arising from maxillary prominences, fuse at the midline, forming the hard and soft palate. This embryonic phenomenon involves a complex array of morphogenetic events that require coordinated proliferation, apoptosis, migration, and adhesion in the PS epithelia and underlying mesenchyme. When the delicate process of craniofacial morphogenesis is disrupted, the result is orofacial clefting, including cleft lip and cleft palate (CL/P). Through human genetic and animal studies, there are now hundreds of known genetic alternations associated with orofacial clefts; so, it is not surprising that CL/P is among the most common of all birth defects...

Nonsyndromic cleft lip and/or palate (NSCL/P) is a prevalent birth defect of complex etiology. Previous studies identified mutations in ARHGAP29 associated with an increased risk for NSCL/P. To investigate the effects of ARHGAP29 in vivo, we generated a novel murine allele by inserting a point mutation identified in a patient with NSCL/P. This single-nucleotide variation of ARHGAP29 translates to an early nonsense mutation (K326X), presumably resulting in loss-of-function (LoF). Embryos from Arhgap29(K326X/+) intercrosses were harvested at various time points...

Quality of life is a valid patient-reported parameter that provides an assessment of treatment need or outcomes complementary to standard clinical measures. Such patient-reported assessments are particularly salient when examining chronic conditions with prolonged treatment trajectories, such as cleft lip and palate. This critical review identifies key questions related to ongoing research on the oral health-related quality of life (OHRQoL) in children with cleft and caregiver well-being. Details of the design and results from 2 longitudinal multicenter studies are presented...

Patients with cleft lip and/or palate (CLP), who undergo numerous medical interventions from infancy, can suffer from lifelong debilitation caused by underdeveloped maxillae. Conventional treatment approaches use maxillary expansion techniques to develop normal speech, achieve functional occlusion for nutrition intake, and improve esthetics. However, as patients with CLP congenitally lack bone in the cleft site with diminished capacity for bone formation in the expanded palate, more than 80% of the patient population experiences significant postexpansion relapse...

OBJECTIVES: Transforming growth factor beta1 (TGF-β1) plays a significant role in craniofacial development. Previous linkage studies reported that the TGF-β1-locus at 19q13.1 harbour predisposing genes for non-syndromic oral clefts. In the present study case parents triads were evaluated to find the transmission effects of genetic variants in TGF- β1 towards non-syndromic cleft lip or palate (NSCL/P). METHODS: Using allelic discrimination method148 families (case-parent triads) were assessed for single nucleotide polymorphisms (SNPs) in TGF-β1 gene...

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...

Amniotic constriction band is a rare clinical entity with varied manifestations that range from a combination of congenital malformations to isolated malformations that are unique to each patient. The etiology of this entity remains unknown. Herein, we highlight two cases of amniotic constriction band that presented to our unit with unique clinical characteristics. To the best of our knowledge, an isolated circumferential band of scarring on the face with ocular involvement, as demonstrated by the first case, and a combination of bilateral complete cleft lip and palate with bilateral microphthalmia, auto-amputation of the right thumb, and a constriction band on the left thumb, as demonstrated by the second case, are extremely rare presentations of amniotic constriction band that were not previously reported in the literature and therefore necessitate a special mention...

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...

BACKGROUND: Previous studies have investigated the relationship between human bone morphogenetic protein 4 gene (BMP4) rs17563 polymorphism and nonsyndromic cleft lip with or without cleft palate (NSCL/P). However, the results remained inconsistent. Therefore, we conducted a meta-analysis to assess the effect of BMP4 rs17563 polymorphism on NSCL/P. METHODS: Electronic searches in 5 databases were conducted to select all eligible studies up to March 2017. Odds ratios (ORs) with the corresponding 95% confidence intervals (CIs) were calculated to estimate the association...

Mutations and common polymorphisms in interferon regulatory factor 6 ( IRF6) are associated with both syndromic and nonsyndromic forms of cleft lip/palate (CLP). To date, much of the focus on this transcription factor has been on identifying its direct targets and the gene regulatory network in which it operates. Notably, however, IRF6 is found predominantly in the cytoplasm, with its import into the nucleus tightly regulated like other members of the IRF family. To provide further insight into the role of IRF6 in the pathogenesis of CLP, we sought to identify direct IRF6 protein interactors using a combination of yeast 2-hybrid screens and co-immunoprecipitation assays...

Oral clefts play an essential role in disturbed odontogenesis of the deciduous and permanent dentition, yet little is known about this relationship. We investigated, within the categories cleft lip with or without alveolus (CL ± A) and cleft lip, alveolus and palate (CLAP), whether different CL subphenotypes based on morphological severity of the cleft show different dentition patterns and whether a more detailed subdivision of the incomplete CL has clinical relevance. In this retrospective study, 345 children with nonsyndromic unilateral CL ± A and CLAP from the Dutch Association for Cleft Palate and Craniofacial Anomalies (NVSCA) registry were included to assess the association between the CL subphenotypes and lateral incisor patterns...

INTRODUCTION: Congenital Cytomegalovirus (CCMV) infection is estimated to occur in 0.5% to 2% of all deliveries across the world. According to the available literature about Human Cytomegalovirus (HCMV) infected children, 0.5% to 1% acquire Cytomegalovirus (CMV) in utero, 40% acquire the infection within the first decade of life, between 15% to 70% acquire CMV infection in group day care settings and continue to shed the virus for 6 to 48 months after primary infection. Although, 90% of the infected infants are clinically asymptomatic at birth, shreds of evidence show that these infants are at risk for audiological, neurological, and developmental sequelae...

BACKGROUND: Orofacial clefts (OFCs), including nonsyndromic cleft lip with or without cleft palate (NSCL/P), are common birth defects. NSCL/P is highly heterogeneous with multiple phenotypic presentations. Two common subtypes of NSCL/P are cleft lip (CL) and cleft lip with cleft palate (CLP) which have different population prevalence. Similarly, NSCL/P can be divided into bilateral and unilateral clefts, with unilateral being the most common. Individuals with unilateral NSCL/P are more likely to be affected on the left side of the upper lip, but right side affection also occurs...

Nutrition is important in every stage of child development. A child born with cleft lip and palate may experience difficulties while feeding due to the lack of seal of the oral cavity due to incomplete facial and palatal structures. Difficulty in feeding leads to inadequate nutrition and affects the health. Children with cleft lip and palate need certain modifications to thrive and grow. Feeding difficulties should be assessed and intervened as early as possible, as they are an important aspect of multidisciplinary team approach in management and may have an impact on long-term outcome...
