Candidate genes for obstructive sleep apnea in non-syndromic children with craniofacial dysmorphisms - a narrative review. Front Pediatr 2023; 11:1117493.

Abstract
Pediatric obstructive sleep apnea (POSA) is a complex disease with multifactorial etiopathogenesis. The presence of craniofacial dysmorphisms influencing the patency of the upper airway is considered a risk factor for POSA development. The craniofacial features associated with sleep-related breathing disorders (SRBD) - craniosynostosis, retrognathia and micrognathia, midface and maxillary hypoplasia - have high heritability and, in a less severe form, could be also found in non-syndromic children suffering from POSA. As genetic factors play a role in both POSA and craniofacial dysmorphisms, we hypothesize that some genes associated with specific craniofacial features that are involved in the development of the orofacial area may be also considered candidate genes for POSA. The genetic background of POSA in children is less explored than in adults; so far, only one genome-wide association study for POSA has been conducted; however, children with craniofacial disorders were excluded from that study. In this narrative review, we discuss syndromes that are commonly associated with severe craniofacial dysmorphisms and a high prevalence of sleep-related breathing disorders (SRBD), including POSA. We also summarized information about their genetic background and based on this, proposed 30 candidate genes for POSA affecting craniofacial development that may play a role in children with syndromes, and identified seven of these genes that were previously associated with craniofacial features risky for POSA development in non-syndromic children. The evidence-based approach supports the proposition that variants of these candidate genes could lead to POSA phenotype even in these children, and, thus, should be considered in future research in the general pediatric population.

Transforming Growth Factor Beta Receptor 2 (TGFBR2) Promoter Region Polymorphisms May Be Involved in Mandibular Retrognathism. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1503052. [PMID: 35757474 PMCID: PMC9217526 DOI: 10.1155/2022/1503052] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Accepted: 05/30/2022] [Indexed: 11/25/2022]
Abstract
Skeletal malocclusions are common phenotypes in humans and have a strong influence on genetic factors. Transforming growth factor beta (TGFβ) controls numerous functions of the human body, including cell proliferation, differentiation, and migration. Thus, this study is aimed at evaluating whether genetic polymorphisms in TGFB1 and its receptor TGFBR2 are associated with mandibular retrognathism in German children and adolescents. Children and teenagers older than 8 years in the mixed or permanent dentition were included in this study. Patients with syndromes and facial trauma and patients with congenital alterations were excluded. Digital cephalometric tracings were performed using the anatomical landmarks point A, point B, sella (S), and nasion (N). Patients that have a retrognathic mandible (SNB < 78°) were selected as case group, and the patients with an orthognathic mandible (SNB = 78°– 82°) were selected as the control group. Genomic deoxyribonucleic acid (DNA) from saliva was used to evaluate four genetic polymorphisms in TGFB1 (rs1800469 and rs4803455) and TGBR2 (rs3087465 and rs764522) using real-time PCR. Chi-square or Fisher exact tests were used to compare gender, genotype, and allele distribution among groups. Genotype distribution was calculated in an additive and recessive model. Haplotype analysis was also performed. The established alpha of this study was 5%. A total of 146 patients (age ranging from 8 to 18 years) were included in this epidemiological genetic study. The genetic polymorphism rs3087465 in TGFBR2 was associated with mandibular retrognathism. Carrying the AA genotype in the rs3087465 polymorphism decreased the chance of having mandibular retrognathism (odds ratio = 0.25, confidence interval 95% = 0.06 to 0.94, p = 0.045). None of the haplotypes was associated with mandibular retrognathism (p > 0.05). In conclusion, we found that the genetic polymorphism rs3087465 in the promoter region of the TGFBR2 was associated with mandibular retrognathism in Germans.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:5048. [PMID: 35564443 PMCID: PMC9101956 DOI: 10.3390/ijerph19095048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 04/15/2022] [Accepted: 04/18/2022] [Indexed: 12/10/2022]
Abstract
This meta-analysis aimed to compare Marfan syndrome (MFS) patients with non-MFS populations based on orofacial health status to combine publicly available scientific information while also improving the validity of primary study findings. A comprehensive search was performed in the following databases: PubMed, Google Scholar, Scopus, Medline, and Web of Science, for articles published between 1 January 2000 and 17 February 2022. PRISMA guidelines were followed to carry out this systematic review. We used the PECO system to classify people with MFS based on whether or not they had distinctive oral health characteristics compared to the non-MFS population. The following are some examples of how PECO is used: P denotes someone who has MFS; E stands for a medical or genetic assessment of MFS; C stands for people who do not have MFS; and O stands for the orofacial characteristics of MFS. Using the Newcastle-Ottawa Quality Assessment Scale, independent reviewers assessed the articles' methodological quality and extracted data. Four case-control studies were analyzed for meta-analysis. Due to the wide range of variability, we were only able to include data from at least three previous studies. There was a statistically significant difference in bleeding on probing and pocket depth between MFS and non-MFS subjects. MFS patients are more prone to periodontal tissue inflammation due to the activity of FBN1 and MMPs. Early orthodontic treatment is beneficial for the correction of a narrow upper jaw and a high palate, as well as a skeletal class II with retrognathism of the lower jaw and crowding of teeth.

Abstract
Purpose of Review
Marfan syndrome (MFS) is an autosomal dominant heritable disorder of fibrillin-1 (FBN1) with predominantly ocular, cardiovascular, and musculoskeletal manifestations that has a population prevalence of approximately 1 in 5–10,000 (Chiu et al. Mayo Clin Proc. 89(1):34–42, 146, Dietz 3, Loeys et al. J Med Genet. 47(7):476–85, 4). Recent Findings The vascular complications of MFS still pose the greatest threat, but effective management options, such as regular cardiac monitoring and elective surgical intervention, have reduced the risk of life-threatening cardiovascular events, such as aortic dissection. Although cardiovascular morbidity and mortality remains high, these improvements in cardiovascular management have extended the life expectancy of those with MFS by perhaps 30–50 years from an estimated mean of 32 years in 1972 (Dietz 3, Gott et al. Eur J Cardio-thoracic Surg. 10(3):149–58, 147, Murdoch et al. N Engl J Med. 286(15):804–8, 148). The musculoskeletal manifestations of MFS, which to date have received less attention, can also have a significant impact on the quality of life and are likely to become more important as the age of the Marfan syndrome population increases (Hasan et al. Int J Clin Pract. 61(8):1308–1320, 127). In addition, musculoskeletal manifestations are often critically important in the diagnosis of MFS. Summary Here, we review the main clinically relevant and diagnostically useful musculoskeletal features of MFS, which together contribute to the “systemic features score” (referred to hereafter as systemic score), part of the revised Ghent nosology for MFS. We discuss current treatment strategies and highlight the need for a multidisciplinary approach to diagnosis and management. Finally, we review new pharmacological approaches that may be disease modifying and could help to improve the outcome for individuals with this syndrome.

Abstract
Orthopaedic surgeons are sometimes the first specialists encountered by patients with inherited conditions that predispose them to aneurysms. The skeletal features are evident, but the aneurysm is silent. Early recognition of the conditions associated with aneurysms can lead to effective treatment and minimize risks of morbidity and death. Marfan syndrome is characterized by abnormal fibrillin-1 protein and has a broad range of skeletal manifestations, including scoliosis, hindfoot deformity, arachnodactyly, pectus excavatum or carinatum deformity, dural ectasia, and acetabular protrusio. Aneurysm-associated complications are the leading cause of early morbidity and death in patients with Marfan syndrome. Ehlers-Danlos syndrome is caused by a disturbance in collagen biosynthesis most commonly resulting in joint hypermobility and skin abnormalities. Among the types of Ehlers-Danlos syndrome, vascular Ehlers-Danlos syndrome presents the highest risk of vascular complications. Clubfoot and joint dislocations are common presenting symptoms in vascular Ehlers-Danlos syndrome. Loeys-Dietz syndrome is a connective tissue disorder resulting in aortic root dilation and several skeletal manifestations, including scoliosis, cervical malformations, joint contractures, and foot deformities.

Abstract
The prevalence of obstructive sleep apnea (OSA) is increased in children and adults with Marfan syndrome (MFS) compared to the general population and has been shown to be associated with rapid aortic root dilation and dissection in adults. Early diagnosis and treatment of OSA may decrease long-term cardiac morbidity. We therefore studied the utility of noninvasive OSA screening tools in children with MFS. We hypothesized that youth with MFS would have higher OSA screening scores than the general pediatric population. Subjects with confirmed MFS were recruited from a single pediatric center. Data collected included cardiac history, retrospective polysomnogram (PSG) data, and prospectively collected Pediatric Sleep Questionnaire (SRBD-PSQ) and Epworth Sleepiness Scale (ESS-CHAD) scores. Fifty-one individuals aged 2-21 years old were identified. Nineteen subjects completed the surveys, 53% female, median age 16 years. Of those that completed the survey, mean SRBD-PSQ score was 0.24 ± 0.21 and mean ESS-CHAD was 6.4 ± 3.7. Comparatively, published normative data for pediatric control subjects were 0.24 ± 0.21 for SRBD-PSQ and 5.4 ± 3.7 for ESS-CHAD. In conclusions, youth with MFS had similar OSA screening scores compared to published pediatric controls. Given these findings and high prevalence of OSA in MFS youth, standard questionnaires may not be an appropriate tool for identifying children at risk for OSA in this population. In the absence of evidence-based guidelines, physicians caring for children with MFS should consider referral for PSG, even in the absence of classic symptoms.

Abstract
INTRODUCTION This study's goal was to determine normal maxillary development on fetal cadavers. MATERIALS AND METHODS This study was carried out on 45 fetuses aged between the 17th - 40th weeks of gestation (24 male, 21 female). The distance between the widest left and right points of the maxillary dental arch (MDA) on the transverse plane, the distance of the papilla incisiva (PI) to the widest left and right points of the maxillary dental arch (MDAW), and the PI and posterior nasal spine (PNS) were measured. The average arch forms of the MDA were created according to trimester groups using the MATLAB program. The one-way ANOVA test was used to make a comparison between trimester groups, and ANOVA followed by post hoc analysis using the Bonferroni test was applied for comparisons. Pearson's correlation analysis was used for correlation analysis. RESULTS The data in the present study did not differ between genders. In the comparison between trimester groups, we did not find any difference between the 3rd trimester and full-term groups only in the PI-MDAW measurement. Other parameters increased with age. In the correlation analysis, the measurement values by age showed a strong positive correlation. The MDAW exhibited the best correlation with age (rweek = 0.919). When the average MDA forms created using the MATLAB program were evaluated, it was observed that the PI-MDAW of the average MDA in the 3rd trimester and full-term intersected. CONCLUSIONS This study provides a basis for a better understanding of fetal maxillary growth processes and can be useful to standardize the detection of malformations or intrauterine growth restrictions.

Abstract
OBJECTIVE To evaluate the relationship between the severity degree of OSA (apnea/hypopnea index AHI>1) and palatal area and volume, measured by 3D analysis of digital casts in Marfan children. METHODS Twenty children with a clinical diagnosis of MS were recruited from a tertiary medical center. All the subjects underwent standard nocturnal polygraphy testing. Sixteen Marfan patients (7F,9 M; mean age 8.8yy ± 1.5yy) with AHI>1 were enrolled. Marfan Group (MG) was compared with a control group (CG) of 17 children without Marfan syndrome (9F,8 M; mean age 8.5yy ± 1.7yy) presenting with nose-breathing pattern. For each subject maxillary digital casts were taken and palatal area and volume were measured. Unpaired t-test was used to test significant differences between MG and CG for area and volume measurements. Pearson correlation coefficient (PCC) was used to measure the linear correlation between the degree of OSA (AHI index) and palatal volume and palatal area. RESULTS 80% of Marfan children presented an AHI>1 and a diagnosis of OSA. MG presented statistically significant lower values of palatal surface area (662.68 mm2; P < 0.0001) and palatal volume (2578.1 mm3; P < 0.0001) with respect to CG (923.0 mm2 and 3756.6 mm3, respectively). Correlation analysis showed that AHI index had no linear correlation with palatal area (r = - 0,07) and with palatal volume (r = - 0,11). CONCLUSION OSA is highly prevalent in children with Marfan's syndrome (80%). Marfan children present a reduction of palatal area and volume when compared to healthy subjects. OSA in Marfan children is not linear correlated to the palatal morphology and it shows a multifactorial aetiology.

Abstract
Marfan's Syndrome is a multisistemic pathology of connective tissues, a dominant autosomal transmission, first discovered by a French pediatrician, Antoine Bernard-Jean Marfan, who first found in some of his patients a disproportionate alteration of inferior infertility. This alteration was caused by the mutation of the FBN1 gene, located on the long arm of the chromosome 15, which encodes for an extracellular matrix protein, fibrin-1. Later it was discovered that the disease could occasionally be due also to the mutation of the TGFBR2 gene, which encodes for a TGF-beta receptor 1. The estimated incidence of the disease is 2-3 subjects affected every 10,000, in the absence of predilection ratial, ethnic, geographic and gender. It is believed that some 15,000 people in Italy suffer from Marfan Syndrome. The disease is characterized by a wide range of clinical manifestations that affect different organs. The study evaluates through a literature review the manifestations in the oral cavity of the marfan syndrome and the correct management of the patient during dental maneuvers.

Abstract
Marfan syndrome (MFS) is caused by abnormal systemic connective tissue. The main clinical manifestations include long limbs, long slender fingers, lens subluxation, abnormal cardiac valves, and aortic aneurysm. We report the case of an 11-year-old patient with MFS who underwent orthodontic treatment and was followed up until the age of 25 years. We found no significant differences in tooth movement between the patient with MFS and healthy subjects. However, because patients with MFS show characteristic facial growth and an increased risk of developing systemic comorbidities, their dental status requires careful observation over time.

Abstract
Marfan syndrome (MFS) is a rare, severe, chronic, life-threatening disease with multiorgan involvement that requires optimal multidisciplinary care to normalize both prognosis and quality of life. In this article, each key team member of all the medical disciplines of a multidisciplinary health care team at the Hamburg Marfan center gives a personal account of his or her contribution in the management of patients with MFS. The authors show how, with the support of health care managers, key team members organize themselves in an organizational structure to create a common meaning, to maximize therapeutic success for patients with MFS. First, we show how the initiative and collaboration of patient representatives, scientists, and physicians resulted in the foundation of Marfan centers, initially in the US and later in Germany, and how and why such centers evolved over time. Then, we elucidate the three main structural elements; a team of coordinators, core disciplines, and auxiliary disciplines of health care. Moreover, we explain how a multidisciplinary health care team integrates into many other health care structures of a university medical center, including external quality assurance; quality management system; clinical risk management; center for rare diseases; aorta center; health care teams for pregnancy, for neonates, and for rehabilitation; and in structures for patient centeredness. We provide accounts of medical goals and standards for each core discipline, including pediatricians, pediatric cardiologists, cardiologists, human geneticists, heart surgeons, vascular surgeons, vascular interventionists, orthopedic surgeons, ophthalmologists, and nurses; and of auxiliary disciplines including forensic pathologists, radiologists, rhythmologists, pulmonologists, sleep specialists, orthodontists, dentists, neurologists, obstetric surgeons, psychiatrist/psychologist, and rehabilitation specialists. We conclude that a multidisciplinary health care team is a means to maximize therapeutic success.

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 2016; 161:448-455.

Abstract
OBJECTIVES The midface of extant Homo sapiens is known to undergo shape changes through fetal and neo-natal ontogeny; however, little work has been done to quantify these shape changes. Further, while midfacial traits which vary in frequency between populations of extant humans are presumed to develop prenatally, patterns of population-specific variation maxillary shape across ontogeny are not well documented. Only one study of fetal ontogeny which included specific discussion of the midface has taken a three-dimensional geometric morphometric approach, and that study was limited to one population (Japanese). The present research project seeks to augment our understanding of fetal maxillary growth patterns, most especially in terms of intraspecific variation. MATERIALS AND METHODS Three-dimensional coordinate landmark data were collected on the right maxillae of 102 fetal and neo-natal individuals from three groups (Euro-American, African-American, "Mixed Ancestry"). RESULTS Shape changes were seen mainly in the lateral wall of the piriform aperture, the anterior nasal spine, and the subnasal alveolar region. The greatest difference across age groups (second trimester, third trimester, neonates) was between the second and third trimester. Euro-Americans and African-Americans clustered by population and differences in midfacial morphology related to ancestry could be discerned as early as the second trimester (p = .002), indicating that population variation in maxillary morphology appears very early in ontogeny. DISCUSSION The midface is a critical region of the skull for assessing ancestry and these results indicate that maxillary morphology may be useful for estimating ancestry for prenatal individuals as young as the second trimester.

Abstract
CONTEXT Meningeal abnormalities such as dural ectasia are seen in Marfan syndrome, but spinal meningeal cysts are rarely seen. These cysts usually asymptomatic and often found incidentally on magnetic resonance imaging, large cysts may cause neurological deficits and pain secondary to nerve root compression. DESIGN Case reports. FINDINGS Two patients with Marfan syndrome presented with urinary symptoms secondary to dural ectasia and sacral cysts. Patient 1 had a history of low back pain, erectile dysfunction, and occasional urinary incontinence and groin pain with recent symptom worsening. He underwent L5 partial laminectomy and S1-S2 laminectomy with sacral cyst decompression. Nine weeks later, he underwent drainage of a sacral pseudomeningocele. Pain and urinary symptoms resolved, and he remains neurologically normal 2 years after surgery. Patient 2 presented after a fall on his tailbone, complaining of low back pain and difficulty urinating. Physical therapy was implemented, but after 4 weeks, urinary retention had not improved. He then underwent resection of the sacral cyst and S1-S3 laminectomy. Pain and paresthesias resolved and bowel function returned to normal. Other than needing intermittent self-catheterization, all other neurologic findings were normal 30 months after surgery. CONCLUSION/CLINICAL RELEVANCE Surgical goals for sacral cysts include resection as well as closure of the dura, which can be challenging due to thinning from ectasia. Neurosurgical intervention in Marfan syndrome is associated with a high risk of dural tears and osseous complications, and should be performed only when symptoms are severe.

Abstract
OBJECTIVE To define normal growth of the fetal maxillary dental arch using magnetic resonance imaging. METHOD Four hundred twenty-four consecutive fetuses (18 to 37 weeks) with a morphologically normal anatomy or only minor malformations, not affecting bone growth and face anatomy were included. On axial T2-weighted images the dental arch length and width were measured. The measurements were correlated with gestational age and the biparietal diameter (BPD) of the fetal head using correlation and regression analysis. RESULTS A linear growth relationship was observed between the dental arch length and gestational age (r = 0.86; p = < 0.0001; y = -1.85 + 0.75 × gestational age) and the dental arch width and gestational age (r = 0.92; p = < 0.0001; y = -2.19 + 1.05 × gestational age). A significant correlation was found between the dental arch length and the BPD (r = 0.903; p = < 0.0001) and the dental arch width and the BPD (r = 0.927; p = < 0.0001). The interobserver variability showed good agreement for the dental arch length (intraclass coefficient 0.981; r = 0.963) and width (intraclass coefficient 0.987; r = 0.974), respectively. CONCLUSION We present a nomogram for the in utero assessment of the fetal dental arch. These data may help in the early detection of abnormal dental arch development.

Abstract
PURPOSE We examined the prevalence of known facial features of Marfan syndrome (MFS)-dolicocephaly, malar hypoplasia, enophthalmos, retrognathia, and down-slanting palpebral fissures-and the diagnostic utility (sensitivity, specificity, accuracy, predictive values, and likelihood ratios) of using them for screening and diagnosis. METHODS Frontal and lateral photographs of 76 subjects with MFS (average age 18.3 years) and of 76 age- and gender-matched controls were obtained, randomized, and compiled into an online survey. Three physicians experienced with MFS rated each photograph for the presence of each feature and indicated whether each photograph triggered a suspicion for MFS. Eight non-expert orthopaedic surgeons reviewed a subset of those photographs and indicated if each triggered a suspicion for MFS. Half of the non-experts then received a brief diagnosis instructional sheet, and all non-experts were retested. The results were compared using Chi-square tests and t-tests with a significance level of P < 0.05. RESULTS Using facial features alone, the accuracy of experienced physicians in identifying individuals with MFS was 73%. Facial features had a 54% sensitivity, a 91% specificity, an 86% positive predictive value (PPV), a 67% negative predictive value (NPV), a 6.9% positive likelihood ratio (PLR), and a 50% negative likelihood ratio (NLR) for MFS. There was no significant difference in the diagnostic accuracy between non-experts receiving and not receiving instructions. CONCLUSIONS Facial features are more specific than sensitive for MFS. Therefore, the recognition of facial features of MFS can be used as an initial screening tool, but facial features do not have a high sensitivity for MFS.

Abstract
A 12-year-old girl with an otherwise typical Marfan syndrome (Ghent criteria fulfilled) presented with highly unusual oral manifestations consisting of supernumerary teeth and severe dental crowding. Pathological examination of the supernumerary teeth revealed an elevated number of pulpoliths. No mutation in the FBN1, TGFBR1 and TGFBR2 genes was identified despite exhaustive screening, suggesting that another gene defect could explain this association of marfanoid features with dental abnormalities.

Abstract
The diagnosis of Marfan syndrome (MFS) is based on evaluating a large number of clinical criteria. We have observed that many persons presenting in specialized centers for "Marfan-like" features do not have MFS, but exhibit a large spectrum of other syndromes. The spectrum of these syndromes and the distribution of "Marfan-like" features remain to be characterized. Thus, we prospectively evaluated 279 consecutive patients with suspected MFS (144 men and 135 women at a mean age of 34+/-13 years) for presence of 27 clinical criteria considered characteristic of MFS. The most frequent reasons to refer individuals for suspected MFS were skeletal features (31%), a family history of MFS, or aortic complications (29%), aortic dissection or aneurysm (19%), and eye manifestations (9%). Using established criteria, we confirmed MFS in 138 individuals (group 1) and diagnosed other connective tissue diseases, both with vascular involvement in 30 (group 2) and without vascular involvement in 39 (group 3), and excluded any distinct disease in 72 individuals (group 4). Clinical manifestations of MFS were present in all four patient groups and there was no single clinical criterion that exhibited positive and negative likelihood ratios that were per se sufficient to confirm or rule out MFS. We conclude that "Marfan-like" features are not exclusively indicative of MFS but also of numerous, alternative inherited diseases with many of them carrying a hitherto poorly defined cardiovascular risk. These alternative diseases require future study to characterize their responses to therapy and long-term prognosis.

Abstract
INTRODUCTION Literature regarding oral conditions in patients with Papillon-Lefèvre syndrome (PLS) often covers the periodontal aspects, but no literature was found describing specific craniofacial findings in this group. The aim of this retrospective study was to investigate the cephalometric findings of patients with PLS. METHODS Lateral cephalograms of 8 patients with PLS were traced, and hard- and soft-tissue variables were analyzed. RESULTS Class III skeletal relationship was evident (ANB angle, 2 degrees +/- 3.1 degrees ; Wits appraisal, -9.1 mm +/- 3.7 mm). Other findings include maxillary retrognathia, decreased lower facial height, retroclined mandibular incisors, and upper lip retrusion. CONCLUSIONS Patients affected with PLS have a Class III skeletal pattern. These findings can be of clinical value not only for diagnosis, but also for proper treatment planning.

Abstract
Marfan's syndrome is a disease associated with reduced structural integrity of connective tissues. We report a 36-year-old patient with Marfan's syndrome who presented with rhinorrhoea, occipital headache and vomiting. Physical examination revealed typical Marfan's syndrome features including dolicocephalous, mandibular micrognathia, tall stature, disproportionately long limbs and digits, and hypermobility of the joints. A high-resolution CT scan demonstrated pneumoencephalous, cerebrospinal fluid (CSF) filling the sphenoidal sinus, and a small bone defect of the clivus. Surgery performed through a transsphenoidal approach revealed the sphenoid sinus to be filled with CSF and a small fenestration in the clivus. The arachnoid diverticulum and the fenestration were repaired and covered with a graft of abdominal fat. In this patient, a deficiency in bone development associated with Marfan's syndrome gave rise to a clival fenestration and a transclival CSF fistula. Although abnormalities of the spinal meningeal membranes have been reported in Marfan's syndrome, to our knowledge, this is the first report of a fistula located in the cranial base in this condition.

Abstract
Marfan syndrome is a widespread disorder of connective tissue. It is characterized by systemic and ocular features due to mutations in the fibrillin gene. Awareness and prompt recognition of the ocular complications of Marfan syndrome may enable improvement and preservation of sight. Studies have been performed in the last few years that enable a better understanding of the genetics of the syndrome, earlier diagnosis, and improvement in the surgical techniques and options.
