Marfan syndrome is a genetic disorder affecting the bodys connective tissues, which help provide strength and flexibility to many parts of the body, including muscles, blood vessels, heart valves, and bones. The two main features of Marfan syndrome affect the heart and eyes. Specifically, the main artery carrying blood away from the heart (aorta) can widen over time (aortic aneurysm). This widening can cause the vessel to tear (aortic dissection). People with Marfan syndrome can also have dislocation of the lenses in their eyes (ectopia lentis), which can cause vision problems. Other features of Marfan syndrome include a long narrow face, a curved spine (scoliosis), a sunken or protruding chest, flat feet, flexible joints, and crowded teeth. People with Marfan syndrome may also have a total length of both arms (wingspan) that is longer than their height.. Marfan syndrome is caused by a mutation (change) in the FBN1 gene. This gene acts as an instruction for the body to make fibrillin-1, a ...

Although not classically associated with Marfan syndrome, colobomata have been described in several reports of Marfan syndrome, typically involving the lens and rarely involving other ocular structures. While colobomata of the lens have been described in Marfan syndrome, there are very few reports of coloboma involving other ocular structures. We report a newborn boy presenting with coloboma of the iris, lens, retina, and optic disk who was subsequently diagnosed with Marfan syndrome. Marfan syndrome is a disorder of ...
By my calculations, there are 9,000 people in the UK who are unaware that they have Marfan Syndrome - if left undetected up to 1/3 of whom may not live beyond adulthood.. Dr. Anne Child, Medical Director of The Marfan TrustThe official figures show that 1:5,000 people potentially have Marfan Syndrome, yet through the incredible work of The Marfan Trust, led by their Medical Director Dr. Anne Childs, it has become apparent that these statistics are inaccurate.Dr Anne Child St. Georges Hospital. The actual figure is believed to be 1:3,000 people, which means that in the UK alone, there are potentially 9,000 who are unaware that they have Marfan Syndrome.. Although Marfan Syndrome is hereditary, 25% of new cases do NOT have any immediate family connections - and it is these people who are most at risk.. This is the exact situation Lucy Morris was in and why it took so long to diagnose her. There will be other girls and boys (as well as adults) throughout the UK in exactly the same situation as ...

Neonatal Marfan syndrome (also called infantile Marfan syndrome) is a term used to designate a severe presentation of Marfan syndrome that is evident in early infancy and shows rapid progression during childhood.
The Marfan syndrome appears to be caused by mutations in a single fibrillin gene on chromosome 15. Diagnosis of the Marfan syndrome by genetic linkage and analysis is now feasible in many families.
Marfan syndrome is a condition where connective tissue is abnormal. This can affect the heart, blood vessels, eyes, lungs, and nervous system.

Marfan syndrome is caused by an abnormality (or mutation) in one specific gene (FBN1). Up to 75 percent of the time, this mutated gene is inherited from a parent who is affected.. Nearly 25 percent of the time, cases are thought to be caused by new mutations in the family (not inherited from a parent). Scientists have noted that offspring of fathers who are older (than the norm) at the time of conception may be affected by this gene mutation more often than others. Mutations occur sporadically (by chance) in the sperm of older men (over 45 years) who father children at a rate of 1 percent. These point mutations can result in Marfan syndrome, or other disorders, depending on which gene is accidentally altered.. Marfan syndrome is an autosomal dominant disorder. This means that each offspring of an affected parent will have a 50 percent chance of also being born with the disorder. Similarly, when a child is born with Marfan syndrome to unaffected parents, the child will have a 50 percent risk of ...

Patients with Marfan syndrome displayed higher rates of aortic complications in long-term follow-up after aortic valve replacement (AVR) than patients with bicuspid aortic valve disease, according to results of a study published June 1 in the Journal of the American College of Cardiology. In a retrospective comparison, Shinobu Itagaki, MD, et al. assessed the long-term follow-up of thoracic aortopathy after AVR in patients with bicuspid aortic valve disease and those with Marfan syndrome. The study compared the outcomes of 13,205 patients-2,079 with bicuspid aortic valves and 73 with Marfan syndrome-who had AVR replacement between 1995 and 2010. The results of the study showed that patients with Marfan syndrome were 14 times more likely to present with aortic dissection during long-term follow-up and five times more likely to undergo thoracic aortic surgery. The authors of the study note that these results provide additional support for the discrete treatment algorithms for patients with ...
Among the Marfan-related conditions is congenital contractural arachnodactyly, which exhibits dolichostenomelia, progressive scoliosis, congenital joint contractures, and deformity of the helix of the ear. Some people with CCA have mitral valve prolapse but aortic dilatation or ectopia lentis should prompt consideration of Marfan syndrome. In most inherited forms of ectopia lentis, findings are limited to the eye. Some families with autosomal dominant ectopia lentis have mild skeletal and cardiovascular features suggestive of the Marfan syndrome, but do not meet diagnostic criteria; some of these families have mutations in FBN1 . Similarly, families lacking ectopia lentis and severe skeletal features, but having mitral valve prolapse, or aortic root dilatation, or both, have been shown, in a few cases, to link to or have mutations in FBN1. However, some families with autosomal dominant aortic aneurysm or dissection, and many sporadic patients with aortic aneurysm do not appear to have a mutation ...
Marfan syndrome is a heritable disorder of connective tissue. It can affect the heart and blood vessels, eyes, and skeleton. In 1896 Dr. Antonine Jean Marfan, a French paediatrician, identified the disorder. Although Marfan syndrome was known since the end of the nineteenth century most of the details where discovered much later, between 1950 and 1990. In some of the following organ systems the Marfan syndrome may cause serious problems:. Heart and blood vessels. Enlargement and stretching of the aorta (dilatation) can cause a dissection or a rupture of the main blood vessel. This is a life threatening event and requires immediate surgery. A prolapse of the heart valves may also necessitate heart surgery.. Eyes. The main ophthalmologic symptoms are myopia, dislocated lenses and retinal detachment. These optical problems can be corrected by glasses, contact lenses or surgery.. Skeleton. Primary orthopaedic problems are curvature of the spine (scoliosis or kyphosis), inward or outward growth of ...
Marfan syndrome is a dominantly inherited connective tissue disorder with a wide range of phenotypic severity. The condition is the result of mutations in FBN1, a large gene composed of 65 exons encoding the fibrillin-1 protein. While mutations causing classic manifestations of Marfan syndrome have been identified throughout the FBN1 gene, the six previously characterized mutations resulting in the severe, perinatal lethal form of Marfan syndrome have clustered in exons 24-32 of the gene. We screened 8 patients with either neonatal Marfan syndrome or severe cardiovascular complications of Marfan syndrome for mutations in this region of the gene. Using intron-based exon-specific primers, we amplified exons 23-32 from genomic DNAs, screened these fragments by single-stranded conformational polymorphism analysis, and sequenced indicated exons. This analysis documented mutations in exons 25-27 of the FBN1 mutations in 6 of these patients. These results, taken together with previously published FBN1 ...
Pediatric researchers at Brenner Childrens Hospital will be testing a new medication for Marfan syndrome. Wesley Covitz, M.D., head of pediatric cardiology, and his team will test whether a drug commonly used to treat high blood pressure will be effective in children and young adults with Marfan Syndrome and will compare their findings with results of the currently used beta-blocker medication. Patients will be given the original beta blocker or an angiotensin receptor blocker (the new medication) to slow the enlargement of the aorta (a large artery which carries blood away from the heart) which can result in sudden tearing of the aorta if left untreated. Both drugs are commonly used to treat high blood pressure in adults and the new drug has been found effective in laboratory studies, Covitz said. Marfan syndrome is a relatively rare genetic condition in which patients lack a gene that allows them to make elastic tissue. Patients with the disease tend to be extremely
The Marfan syndrome is an inherited multisystem disorder caused by mutations in fibrillin 1, with cardiovascular involvement being the most important feature of the phenoptype. Affected individuals have impaired flow-mediated dilatation (FMD) of large arteries of a similar severity to patients with chronic heart failure (CHF).Skeletal muscle bioenergetics were studied in patients with the Marfan syndrome in order to evaluate the impact of impaired flow-mediated dilatation on skeletal muscle metabolism. Skeletal muscle metabolism is abnormal in CHF and the aetiology is unclear.Thirteen patients and 12 controls were studied by phosphorus Magnetic Resonance spectroscopy of the calf muscle using an incremental exercise protocol and by Magnetic Resonance imaging.Metabolic variables measured at rest were normal in Marfan patients. For a similar total work output measured at end of the standardized incremental exercise, the total rate of energy consumption (EC) was significantly increased in patients (21.2 +/-

Marfan syndrome affects three major organ systems of the body: the heart and circulatory system, the bones and muscles, and the eyes. The genetic mutation responsible for Marfan was discovered in 1991. It affects the bodys production of fibrillin, which is a protein that is an important part of connective tissue. Fibrillin is the primary component of the microfibrils that allow tissues to stretch repeatedly without weakening. Because the childs fibrillin is abnormal, his or her connective tissues are looser than usual, which weakens or damages the support structures of the entire body. The most common external signs associated with Marfan syndrome include excessively long arms and legs, with the childs arm span being greater than his or her height. The fingers and toes may be long and slender, with loose joints that can be bent beyond their normal limits. This unusual flexibility is called hypermobility. The childs face may also be long and narrow, and he or she may have a noticeable ...
Background. Pathogenic mutations in FBN1, encoding the glycoprotein, fibrillin-1, cause Marfan syndrome (MFS) and related connective tissue disorders. In the present study, qualitative and quantitative effects of 16 mutations, identified in FBN1 in MFS patients with systematically described phenotypes, were investigated in vitro.. Methods. Qualitative analysis was performed with reverse transcription-PCR (RT-PCR) and gel electrophoresis, and quantitative analysis to determine the FBN1 mRNA levels in fibroblasts from the 16 patients with MFS was performed with real-time PCR.. Results. Qualitative analysis documented that the mutations c.4817-2delA and c.A4925G led to aberrant FBN1 mRNA splicing leading to in frame deletion of exon 39 and in exon 39, respectively. No difference in the mean FBN1 mRNA level was observed between the entire group of cases and controls, nor between the group of patients with missense mutations and controls. The mean expression levels associated with premature ...
Formation of aortic aneurysms as a consequence of augmented transforming growth factor β (TGF-β) signaling and vascular smooth muscle cell (VSMC) dysfunction is a potentially lethal complication of Marfan syndrome (MFS). Here, we examined VSMC senescence in patients with MFS and explored the potential mechanisms that link VSMC senescence and TGF-β. Tissue was harvested from the ascending aorta of control donors and MFS patients, and VSMCs were isolated. Senescence-associated β-galactosidase (SA-β-gal) activity and expression of senescence-related proteins (p53, p21) were significantly higher in aneurysmal tissue from MFS patients than in healthy aortic tissue from control donors. Compared to control-VSMCs, MFS-VSMCs were larger with higher levels of both SA-β-gal activity and mitochondrial reactive oxygen species (ROS). In addition, TGF-β1 levels were much higher in MFS- than control-VSMCs. TGF-β1 induced VSMC senescence through excessive ROS generation. This effect was suppressed by Mito-tempo,
FBN1 (15q21.1) encodes fibrillin-1, a large glycoprotein which is a major component of microfibrils that are widely distributed in structural elements of elastic and non-elastic tissues. FBN1 variants are responsible for the related connective tissue disorders, grouped under the generic term of type-1 fibrillinopathies, which include Marfan syndrome (MFS), MASS syndrome (Mitral valve prolapse, Aortic enlargement, Skin and Skeletal findings, Acromicric dysplasia, Familial ectopia lentis, Geleophysic dysplasia 2, Stiff skin syndrome, and dominant Weill-Marchesani syndrome. Two siblings presented with isolated skeletal manifestations of MFS, including severe pectus excavatum, elongated face, scoliosis in one case, and absence of other clinical features according to Ghent criteria diagnosis, were screened for detection of variants in whole FBN1 gene (65 exons). Both individuals were heterozygous for the R2726W variant. This variant has been previously reported in association with
Purpose: Patients with Marfan syndrome are at high risk of significant retinal pathology including retinal detachments. Examination of these patients is often difficult due to poorly dilating pupils, subluxated lens and young age. This study aimed to report the prevalence of peripheral retinal disease, using the Optos 200Tx imaging device, in a group of Marfan patients.. Methods: 72 patients were seen on August 2nd as a part of 2012 Marfan Eye Consortium of Chicago. Of the 61 consented patients, posterior color ultra-widefield retinal images were obtained using the Optos 200Tx (age range of tested patients 3-56yrs) on 54 patients (108 eyes). The ability to view the fundus was divided into 2 groups for analysis. Post-equator category: Eyes in which we were able to view posterior pole up to equator) and anterior to equator: eyes where the examiner had sufficient retina view anterior to equator of the peripheral retina. The ultra-widefield color images were analyzed by vitreo-retinal ...
The diagnosis of Marfan syndrome (MFS) relies on defined clinical criteria (Ghent nosology), outlined by international expert opinion to facilitate accurate recognition of this genetic aneurysm syndrome and to improve patient management and counselling. These Ghent criteria, comprising a set of major and minor manifestations in different body systems, have proven to work well since with improving molecular techniques, confirmation of the diagnosis is possible in over 95% of patients. However, concerns with the current nosology are that some of the diagnostic criteria have not been sufficiently validated, are not applicable in children or necessitate expensive and specialised investigations. The recognition of variable clinical expression and the recently extended differential diagnosis further confound accurate diagnostic decision making. Moreover, the diagnosis of MFS-whether or not established correctly-can be stigmatising, hamper career aspirations, restrict life insurance opportunities, and ...

Aortic dissection is a well-known complication of Marfan syndrome. Aortic dissection in patients with Marfan syndrome is associated with aortic root dilatation. As imaging techniques have improved, it has become clear that some patients with Marfan syndrome, in the absence of symptoms, may have evidence of a prior aortic dissection. A 47-year-old white man with documented Marfan syndrome and no prior symptomatology referable to aortic dissection had elective high-resolution MRI of the aorta for an unrelated research project. Importantly, he had no known risk factors for atherosclerotic disease. The MR images showed that his aortic root was not dilated, with a diameter of 36 mm (Figure 1A⇓). His ascending aorta was not dilated, with normal wall thickness and no evidence of an intimal flap (Figure 1B⇓). However, a small defect was evident in the wall of the descending thoracic aorta that was more readily appreciated on magnified views of the region (Figure 2⇓). Proton density-weighted ...
BACKGROUND: Marfan syndrome (MFS) is a disorder of autosomal dominant inheritance, in which aortic root dilation is the main cause of morbidity and mortality. Fibrillin-1 (FBN-1) gene mutations are found in more than 90% of MFS cases. The aim of our study was to summarise variants in FBN-1 and establish the genotype-phenotype correlation, with particular interest in the onset of aortic events, in a broad population of patients with an initial clinical suspicion of MFS. MATERIAL AND METHODS: This single centre prospective cohort study included all patients presenting variants in the FBN-1 gene who visited a Hereditary Aortopathy clinic between September 2010 and October 2016 ...
Aortic pathology can have devastating consequences with significant morbidity and mortality. Marfan syndrome patients have a profound predisposition to develop aortic root pathology and can develop complications of aortic root pathology such as aneurysm of the aorta (especially the aortic root), aortic dissection and aortic valve regurgitation. Recent advances in understanding the pathophysiology of the consequences of fibrillin-1 deficiency in Marfan syndrome and the development of murine models of this condition have opened up the possibility for translational research to be conducted in this area. Potential pharmacological treatments can now be extensively researched prior to clinical trials. Pravastatin, a 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitor has been shown to have a beneficial effect on atherosclerosis via

Thoracic aortic aneurysms can be triggered by genetic disorders such as Marfan syndrome (MFS) and related aortic diseases as well as by inflammatory disorders such as giant cell arteritis or atherosclerosis. In all these conditions, cardiovascular risk factors, such as systemic arterial hypertension, may contribute to faster rate of aneurysm progression. Optimal medical management to prevent progressive aortic dilatation and aortic dissection is unknown. β-blockers have been the mainstay of medical treatment for many years despite limited evidence of beneficial effects. Recently, losartan, an angiotensin II type I receptor antagonist (ARB), has shown promising results in a mouse model of MFS and subsequently in humans with MFS and hence is increasingly used. Several ongoing trials comparing losartan to β-blockers and/or placebo will better define the role of ARBs in the near future. In addition, other medications, such as statins and tetracyclines have demonstrated potential benefit in ...
Objective: Marfan syndrome (MFS), an inherited defect in the extracellular matrix protein fibrillin, is associated with an increased incidence of ascending thoracic aortic aneurysms (ATAAs) which may occur through different mechanisms than ATAAs resulting from other causes. Protein kinase C (PKC) is an intracellular signaling enzyme family characterized into three subclasses (conventional, novel, and atypical) based on co-factor requirements for activation. Recent evidence has linked changes in PKC expression and activity to aneurysm formation. This study tested the hypothesis that differential PKC isoform profiles are present in ATAAs in MFS compared to degenerative ATAAs in patients with tricuspid aortic valves (TAV).. Methods: A comprehensive profile of PKC isoforms was measured by quantitative immuno-blotting in surgical ATAA specimens from 8 patients with MFS, 55 patients with TAV and a reference control group (n=21) of normal ascending aortic specimens. Results (mean ± SEM) are expressed ...
Marfan syndrome is a genetic connective tissue disorder caused by a defect in gene FBN1, which codes for abnormal structure of fibrillin-1, a protein crucial for formation of normal connective tissue.
The Marfan Syndrome, Loeys-Dietz Syndrome, Familial Thoracic Aortic Aneurysms & Dissections, and Related Disorders NGS Panel is designed to be a cost effective method for detecting mutations in genes causing aneurysms of the aorta and its major branches. Mutations in the genes on this panel cause numerous disorders with variable but often overlapping phenotypes that should be considered in the differential diagnosis of patients presenting with aneurysms. In many instances, different mutations within any gene have been reported to result in variable phenotypes. The genes constituting this panel have been carefully selected so that they are truly representative of those associated with aneurysms of the major vessels. The Marfan syndrome, Loeys-Dietz syndrome, Familial thoracic aortic aneurysms & dissections, and related disorders NGS panel consists of twenty-eight genes: ACTA2, BGN, CBS, COL3A1, COL5A1, COL5A2, FBN1, FBN2, FLNA, FOXE3, LOX, LTPB3, MAT2A, MFAP5, MED12, MYH11, MYLK, NOTCH1, PRKG1, ...
An inherited disorder of connective tissue that is characterized by abnormalities of the eyes, skeleton, and cardiovascular system. Nearsightedness (myopia) is the most common eye feature in Marfan syndrome. Displacement of the lens from the center of the pupil occurs in more than half of patients. Patients with Marfan syndrome have an increased risk for retinal detachment, glaucoma, and early cataracts. The skeleton shows bone overgrowth and loose joints. The arms and legs are unusually long, as are the fingers and toes. Due to overgrowth of the ribs, the sternum may be pushed in (pectus excavatum) or out (pectus carinatum). Scoliosis is common. Cardiovascular manifestations in Marfan syndrome include enlargement of the aorta at the level of the aortic valve, aortic aneurysm, prolapse of the mitral and tricuspid valves, and enlargement of the pulmonary artery. The major causes of disease and death in the syndrome are related to the heart and blood vessels. Marfan syndrome is inherited in an ...
A genetic study has suggested that autosomal dominant Weill-Marchesani syndrome and Marfan syndrome are allelic diseases. Two large families with autosomal dominant Weill-Marchesani syndrome were studied. They were the same families whose condition was previously shown to be linked to chromosome 15q21.1, to the fibrillin-1 gene locus. Fibrillin-1 mutations cause Marfan syndrome, and the two syndromes are clinically similar.. In family 1 Weill-Marchesani syndrome was consistent with linkage to chromosome 15q21.1 and chromosome 19p13.3-p13.2; in family 2 linkage to chromosome 19 was excluded for all six affected members. A deletion in exon 41 of the fibrillin-1 gene was apparent in family 1, and sequence analysis showed heterozygosity for a 24 nucleotide in frame deletion, which segregated with affected family members but was not present in 186 controls of European origin. No mutation was identified in family 2, maybe because of a low rate of mutation, as in Marfan syndrome.. Affected members of ...

TY - JOUR. T1 - Histopathologic findings in ascending aortas from individuals with Loeys-Dietz Syndrome (LDS). AU - Maleszewski, Joseph J.. AU - Miller, Dylan V.. AU - Lu, Jie. AU - Dietz, Harry C.. AU - Halushka, Marc K.. PY - 2009/2/1. Y1 - 2009/2/1. N2 - Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder resulting from genetic mutations in the transforming growth factor β receptors 1 and 2 (TGFBR1 and TGFBR2). The syndrome is characterized phenotypically by hypertelorism, bifid uvula, and/or cleft palate, and arterial tortuosity with aneurysms and dissections. LDS has a much more rapid clinical course than Marfan syndrome (MFS) and thus those diagnosed with LDS are currently being recommended for prophylactic aortic root replacement at younger ages and with smaller aortic dimensions. Aortic root tissue obtained at surgery was compared between 15 patients carrying a diagnosis of LDS, 11 patients with MFS and 11 control aortas to evaluate the range of ...

Loeys-Dietz syndrome is a recently-discovered autosomal dominant genetic syndrome which has many features similar to Marfan syndrome, but which is caused by mutations in the genes encoding transforming growth factor beta receptor 1 (TGFBR1) or 2 (TGFBR2). It was identified and characterized by American physician Harry C. Dietz and Belgian physician Bart L. Loeys, for whom it is named. From: Wikipedia: Loeys-Dietz Syndrome
The fibrillinopathy panel is designed to detect mutations in genes that produce disorders that have similar, if not in at least some patients, identical phenotypes. These include: Marfan syndrome or Marfan like disorders caused by FBN1 mutations, congenital contractural arachnodactyly also known as Beals syndrome or arthrogryposis, distal, type 9, caused by mutations in FBN2, and homocystinuria caused by mutations in CBS.. Clicking on the individual genes listed below will link to a brief description of each disorder. Note: The presence or absence of ectopia lentis or the direction of lens dislocation has been used as a guide to clinically discriminate between these disorders. This practice seems to be controversial and probably should not be a major determinant to establish a final diagnosis.. Copy number variation (CNV) analysis of the fibrillinopathy genes is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes. Panel genes are also ...
Bicuspid aortic valve (BAV) is a common (0.5-2.0% of general population) congenital heart defect with increased prevalence of aortic dilatation and dissection. BAV has an autosomal dominant inheritance with reduced penetrance and variable expressivity. BAV has been described as an isolated trait or associated with syndromic conditions [e.g., Marfan Marfan syndrome or Loeys-Dietz syndrome (MFS, LDS)]. Identification of a syndromic condition in a BAV patient is clinically relevant to personalize aortic surgery indication. A 4-fold increase in BAV prevalence in a large cohort of unrelated MFS patients with respect to general population was reported, as well as in LDS patients (8-fold). It is also known that BAV is more frequent in patients with thoracic aortic aneurysm (TAA) related to mutations in ACTA2, FBN1, and TGFBR2 genes. Moreover, in 8 patients with BAV and thoracic aortic dilation, not fulfilling the clinical criteria for MFS, FBN1 mutations in 2/8 patients were identified suggesting that ...

Methods and results Using gene panel sequencing, we identified a SMAD2 nonsense variant and four SMAD2 missense variants, all affecting highly conserved amino acids in the MH2 domain. The premature stop codon (c.612dup; p.(Asn205*)) was identified in a marfanoid patient with aortic root dilatation and in his affected father. A p.(Asn318Lys) missense variant was found in a Marfan syndrome (MFS)-like case who presented with aortic root aneurysm and in her affected daughter with marfanoid features and mild aortic dilatation. In a man clinically diagnosed with Loeys-Dietz syndrome (LDS) that presents with aortic root dilatation and marked tortuosity of the neck vessels, another missense variant, p.(Ser397Tyr), was identified. This variant was also found in his affected daughter with hypertelorism and arterial tortuosity, as well as his affected mother. The third missense variant, p.(Asn361Thr), was discovered in a man presenting with coronary artery dissection. Variant genotyping in three unaffected ...
Marfan syndrome. The history and physical examination is consistent with diagnosis of aortic regurgitation. In Marfan syndrome, syphilis, and Takayasu s arteritis, aortic regurgitation is caused by dilatation of the aortic root. Dilatation causes the aortic annulus to stretch, leading to incomplete opposition of valve leaflets during the aortic valve closure and resulting in regurgitation of blood from the aorta into the left ventricle. In rheumatic heart disease and bicuspid aortic valve disease (which are more common causes of aortic regurgitation), the valve leaflets are abnormal and aortic root is normal. Early diastolic murmur caused by aortic regurgitation is better heard on the right side of the sternum if the regurgitation results from aortic dilatation (as is seen in the patient presented here) and best heard on the left side due if the cause is abnormal valves. Therefore, rheumatic heart disease and bicuspid valve disease can be ruled out. Of the remaining conditions, Marfan syndrome ...
Loeys-Dietz syndrome (LDS) is an autosomal dominant genetic connective tissue disorder. It has features similar to Marfan syndrome and Ehlers-Danlos syndrome. The disorder is marked by aneurysms in the aorta, often in children, and the aorta may also undergo sudden dissection in the weakened layers of the wall of aorta. Aneurysms and dissections also can occur in arteries other than the aorta. Because aneurysms in children tend to rupture early, children are at greater risk for dying if the syndrome is not identified. Surgery to repair aortic aneurysms is essential for treatment. There are four types of the syndrome, labelled types I through IV, which are distinguished by their genetic cause. Type 1, Type 2, Type 3, and Type 4 are caused by mutations in TGFBR1, TGFBR2, SMAD3, and TGFB2 respectively. These four genes encoding transforming growth factors play a role in cell signaling that promotes growth and development of the bodys tissues. Mutations of these genes cause production of proteins ...
The normal range for aortic root diameters employing the echocardiographic continuous recording technique was determined in 159 adult subjects without aortic valve disease or hypertension. In order to evaluate the accuracy of this noninvasive technique, the aortic root diameters as measured by ultrasound before operation in 31 patients with aortic valve disease were compared with their respective aortic annulus diameters as determined at the time of valve replacement. The 159 normal subjects consisted of 78 men and 81 women whose ages ranged from 18 to 74 pears (average 38). The normal range of aortic root diameters in this group was 17 to 33 mm (mean 23.7). A significant difference (P is smaller than 0.001) in aortic root diameters existed between men and women which could not be explained by differences in body surface area. The mean diameter among the 81 women was 22.4 plus or minus 3.3 mm(I SD) compared to the mean diameter in the 78 men of 25 plus or minus 3.5 mm. These results indicate a ...
Introduction: Current guidelines recommend patients with thoracic aortic disease (TAD) including inherited aortopathies to avoid heavy exercise. However, evidence supporting the negative advice on exercise is scarce. We aimed to provide an up-to-date systematic review of the available evidence on risks and benefits of exercise and sports participation in TAD patients. Areas covered: A systematic search was performed in Medline, Embase and Web of Science: thoracic aortic aneurysm or thoracic aortic dissection or inheritable aortopathies including Marfan Syndrome (MFS), Loeys-Dietz syndrome, Turner Syndrome, Ehlers-Danlos syndrome, bicuspid aortic valve (BAV) and sports, exercise or athletes. The resulting 1,652 manuscripts were reviewed by two independent observers. Eventually, 26 studies and 12 case-reports were included, reporting on thoracic aortic dimensions in athletes, exercise related acute aortic dissections, and exercise in BAV and MFS patients. Expert opinion: Blood pressure elevation ...

Approach and Results-Aortic senescence strongly correlates with aortic root dilatation rate in MFS mice. However, although resveratrol inhibits aortic dilatation, it only shows a trend toward reduced aortic senescence. Resveratrol enhances nuclear localization of sirtuin-1 in the vessel wall and, in contrast to losartan, does not affect leukocyte infiltration nor activation of SMAD2 and extracellular signal-regulated kinases 1/2. Interestingly, specific sirtuin-1 activation (SRT1720) or inhibition (sirtinol) in MFS mice does not affect aortic root dilatation rate although senescence is changed. Resveratrol reduces aortic elastin breaks and decreases micro-RNA-29b expression coinciding with enhanced antiapoptotic Bcl-2 expression and decreased number of terminal deoxynucleotidyl transferase dUTP nick-end labeling-positive cells. In cultured smooth muscle cells, the resveratrol effect on micro-RNA-29b downregulation is endothelial cell and nuclear factor κB dependent. ...
TY - JOUR. T1 - The trap-door technique for coronary reimplantation in aortic root surgery. AU - Mariani, Silvia. AU - Thomas, Laura H.. AU - Peek, Giles J.. PY - 2016/8/1. Y1 - 2016/8/1. N2 - Coronary ostia reimplantation is a crucial stage of every aortic root replacement procedure. The button technique is currently the most used method and it has shown satisfactory outcomes over time. However, coronary reimplantation techniques still present drawbacks such as pseudoaneurysm formation, kinking, bleeding and coronary dehiscence, especially when coronaries are hard to mobilize. We adapted the trap-door technique, commonly used in the arterial switch operations, in order to apply it in older patients requiring an aortic root replacement procedure. The key passage of such a technique is the creation of an L-shaped trap-door flap in the conduit graft in order to produce a cone-like extension of the conduit from which the coronary ostium can arise. We applied this technique in 24 patients over 8 ...
The present epidemiologic community-based echocardiographic study shows that patients with a bicuspid aortic valve without hemodynamically significant stenosis or regurgitation have a larger aortic anulus, aortic sinus, and proximal ascending aorta compared with controls with normal tricuspid aortic valves. The two groups were matched with respect to age, sex, and body surface area to eliminate confounding, because these variables do influence aortic dimensions.25,26⇓ In addition, none of the BAV cases or controls had Marfan syndrome or a family history of Marfan syndrome, and the prevalence of hypertension in each group was low. Both cases and controls are from a geographically defined population of Olmsted County, Minnesota, which helps eliminate geographic variation and reduce referral bias inherent in studies from tertiary medical centers. Importantly, none of the BAV patients were referred to the echocardiography laboratory because of aortic dilatation.. There is biologic rationale and ...
In 1962, a Los Angeles physician diagnosed a 7-year-old boy with Marfan syndrome, a dominant genetic disorder that leads to a whole variety of complications, including early death from a ruptured heart. The patient was an indirect descendent of Abraham Lincoln (Lincoln left no direct progeny), and the physician speculated that perhaps Lincoln had the same disorder. One symptom of Marfan is unusual height; Abe Lincoln was well over six feet tall, which was highly unusual for the mid-19th century. When the gene for Marfan was discovered in 1991, an interesting question was raised: Would it be possible to obtain some DNA from Lincoln and see whether he had the disorder? After all, it would give Marfan patients some comfort to know they were in good company. Philip Reilly, a geneticist, lawyer, and CEO of Interleukin Genetics, Inc., of Waltham, Mass., uses Lincolns case as the title piece to his book, Abraham Lincolns DNA, and Other Adventures in Genetics. He is an M.D. who gives courses at ...

To our knowledge this is the first description of aortic root perforation by a septal occluder in a patient with Marfan syndrome. There are only a few cases that report destruction of aortic segments after placement of closure devices in patients with patent foramen ovale (PFO), patent ductus arteriosus (PDA) or ASD [4-7]. Perforation is a rare event, occurring in approximately 0.1% of all cases, indicating closure devices are generally safe. The mechanism of perforation is not well understood but it might be related to the absence or presence of the anterosuperior and posteroinferior rims of the atrial septum where the closure device is fixed in position [8, 9]. Interestingly perforations are observed uniquely in the anterosuperior wall and the adjacent aorta [10].. In patients with an altered connective tissue, the reason for dislocation of closure devices might be different. Thus far, we know that the affected protein Fibrillin in Marfan syndrome, plays a crucial role in maintaining the ...

Although the lions share of the credits for a healthy cornea, from transparency to biomechanical strength, goes to fibrillar collagens, the less touted elastic microfibrils get a closer look in this issue. Microfibrils (∼10-12 nm in diameter) in the extracellular matrix are composed of fibrillin polymers associated with elastin, other glycoproteins, and growth factors to provide a dynamic signaling platform for cells.1 Mutations in the fibrillin (FBN) glycoproteins, encoded by FBN1, FBN2, and FBN3, are associated with multiple connective tissue disorders, the most notable being FBN1 causing Marfan syndrome (MFS),2 in which microfibril ultrastructures were examined in the skin and aorta. Recent studies combine high-resolution electron and immunofluorescent microscopy with three-dimensional reconstruction to gain new insights into the cornea. Thus, microfibrils carry an elastin core in the sclera, extending into elastin-free microfibrils in the cornea, possibly to balance elasticity with ...
They help sort the forest from the trees, researchers say. Timely and early diagnosis of both genetic disorders can mean the difference between life and death, but some of the most common physical features are also found in people with neither of the syndromes, which can cause confusion.. Published as two separate studies in the August issue of the Journal of Bone and Joint Surgery, the two lists enumerate physical features that in certain combinations are highly suggestive of either Marfan or Loeys-Dietz syndromes, connective tissue disorders similar in presentation but caused by different genetic glitches. Many of the signal features of these disorders involve the face, skull, joints and spine, making them easy to spot during a physical exam, but not always easy to sort out.. The beauty of our lists is that they require no fancy imaging tests and most of the signs are right there for the pediatricians and the orthopedic surgeons to see, says co-investigator Paul Sponseller, M.D. M.B.A., ...

The extracellular glycoprotein fibrillin-1 forms microfibrils that act as the template for elastic fibers. Most mutations in fibrillin-1 cause Marfan syndrome with severe cardiovascular and ocular symptoms, and tall stature. This is in contrast to mutations within a heparin-binding TB domain (TB5), which is downstream of the arg-gly-asp cell adhesion domain, which can cause Weill-Marchesani syndrome (WMS) or Acromicric (AD) and Geleophysic Dysplasias (GD). WMS is characterized by short limbs, joint stiffness and ocular defects, whilst fibrillin-1 AD and GD have severe short stature, joint defects and thickened skin ...

We present here a family with a clinical phenotype resembling Marfan syndrome (MFS), and displaying joint contracture and episodes of knee joint effusions, but lacking the cardiovascular features of the syndrome. The phenotype of this family represents a unique mixture of connective tissue symptoms, some of which are found in classical MFS and some of which are typical of dominant ectopia lentis. Linkage analyses suggested a linkage (LOD score 2.4; theta = 0) between the phenotype of the family and a polymorphic marker in the vicinity of the fibrillin locus on chromosome 15 (FBN1). Furthermore, a novel transition mutation was identified in the FBN1 gene in all the affected members of the family. In contrast to the majority of fibrillin mutations reported so far, this mutation substitutes a cysteine for arginine, producing an extra cysteine in one of the non-calcium-binding EGF-like motifs of the fibrillin polypeptide, most probably disturbing the formation of one of the three disulfide bridges ...
I live in the UK, and suffer from a complex heritable connective tissue disorder named Marfan syndrome. In my case, expression is severe - I present with an ascending aortic aneurysm, levoscoliosis, prominent spur formation, prominent Schmorls node formation, facet joint arthropathy, disc desiccation (particularly at the L5-S1 region), multilevel annular bulges, severe osteoarthritis, osteoporosis, TMJ, high myopia, increased risk of retinal detachment, bone marrow signal changes indicative of fatty degeneration, bone infarcts above and below both knees, a pectus excavatum, skeletal abnormalities, and other manifestations of this syndrome. I have received, and continue to receive, extensive treatment at the hands of the NHS - and have nothing but praise for this institution.

Background Marfan symptoms (MFS) is a problem of autosomal prominent inheritance, where aortic main dilation may be the main reason behind morbidity and mortality. acquired missense mutations, 6 of whom acquired experienced an aortic event (with either prophylactic medical procedures for aneurysm or dissection), whereas 20 from the 35 sufferers with mutations acquired suffered a meeting (13.6% vs. 57.1%, in comparison to people that have mutations, but not significantly (41.33??3.77 vs. 37.5??9.62?years, variations in FBN-1 presented an increased percentage of aortic occasions, compared to a far more benign program in individuals with mutations.
