AbstractMutations in fibrillin 1 cause Marfan syndrome (MFS), an autosomal dominant disorder of the connective tissue, with multisystem manifestations. In early-onset MFS, the physical characteristics are expressed much earlier than the classical MFS. Those affected by this form generally have their mutations restricted to the gene “hotspot” region of exons 24 to 32. Historically, affected individuals usually die within the first few years of life due to heart failure secondary to severe valvular insufficiency. We report three patients with early-onset MFS, whose clinical evolution has been remarkably positive, when compared with other reported cases in the literature.

Systemic Disorder

Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Children affected by the Marfan syndrome carry a mutation in one of their two copies of the gene that encodes the connective tissue protein fibrillin-1. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessel that distributes blood from the heart to the rest of the body. A case report of Marfan syndrome has been reported with oral features. The dental problems of the child were treated under general anesthesia and a one-month review showed intact stainless steel crowns' restorations and no signs of secondary caries.

Duane Retraction Syndrome

Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue, while Duane retraction syndrome (DRS) is a congenital cranial dysinnervation disorder (CCDD) which can be transmitted as autosomal dominant disorder in 5–10% of patients. In this paper, we present an 8-year-old girl who presented with left eye DRS and bilateral subluxation of the lens associated with MFS in absence of familial involvement. To our knowledge this is the first case report of DRS with MFS. The occurrence of these syndromes together is very rare and appears to be coincidental.

Fibrillin 1

Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue, caused by mutations of the microfibrillar protein fibrillin-1, that predisposes affected individuals to aortic aneurysm and rupture and is associated with increased TGFβ signaling. TGFβ is secreted from cells as a latent complex consisting of TGFβ, the TGFβ propeptide, and a molecule of latent TGFβ binding protein (LTBP). Improper extracellular localization of the latent complex can alter active TGFβ levels, and has been hypothesized as an explanation for enhanced TGFβ signaling observed in MFS. We previously reported the absence of LTBP-3 in matrices lacking fibrillin-1, suggesting that perturbed TGFβ signaling in MFS might be due to defective interaction of latent TGFβ complexes containing LTBP-3 with mutant fibrillin-1 microfibrils. To test this hypothesis, we genetically suppressed Ltbp3 expression in a mouse model of progressively severe MFS. Here, we present evidence that MFS mice lacking LTBP-3 have improved survival, essentially no aneurysms, reduced disruption and fragmentation of medial elastic fibers, and decreased Smad2/3 and Erk1/2 activation in their aortas. These data suggest that, in MFS, improper localization of latent TGFβ complexes composed of LTBP-3 and TGFβ contributes to aortic disease progression.

BackgroundMarfan syndrome (MFS) is an autosomal dominant disorder of fibrillin-1 gene mutations, with the involvement of cardiovascular, skeletal, and ocular systems. In addition to physical abnormalities, MFS patients are also found to be susceptible to schizophrenia and other psychiatric conditions.ObjectivesAwareness of the association between MFS and psychiatric conditions would improve the clinical management of MFS patients to reduce the risk or even to prevent the development of psychiatric complications in MFS patients.MethodsHere, we describe a male MFS patient who manifested incoherent speech and impaired cognitive and social function at the age of 40 years.Results and conclusionHis mental dysfunction could be attributed to his bilateral cerebral infarction, which is a neurovascular complication associated with MFS.

Fibrillin 1

Mutations in the FBN1 gene encoding the microfibrillar glycoprotein fibrillin cause Marfan syndrome, a relatively common autosomal dominant connective tissue disease. Causative FBN1 mutations appear to be dispersed throughout the coding frame, and to date no predictable genotype: phenotype correlations have emerged. We have identified a point mutation within an eight-cysteine ‘hybrid’ motif of the fibrillin polypeptide which results in the substitution of an arginine for a cysteine, in a patient severely affected in the cardiovascular, skeletal and ocular systems. We have utilised cell cultures from various tissues of this patient to investigate the effects of this mutation on fibrillin expression and deposition, and the consequences in terms of microfibril assembly and organisation. We have established that there is no difference in the expression of normal and mutant alleles, and fibrillin synthesis, secretion and deposition are also normal. However, the rate of fibrillin aggregation is reduced and microfibrillar assemblies are both remarkably scarce and morphologically abnormal. These data clearly demonstrate that the mutated allele interferes with normal assembly, and strongly implicate this particular region of the fibrillin-1 molecule in stabilising microfibrillar assemblies.

Fibrillin 1

Recent research on the molecular physiology of fibrillin and the pathophysiology of Marfan syndrome and related connective tissue disorders has changed our understanding of this pathology by demonstrating changes in growth factor signalling and in matrix-cell interactions. Marfan syndrome is an autosomal dominant disorder of connective tissue caused by mutations in fibrillin-1. Fibrillin-1 contributes to the regulated activation of the cytokine TGF-ß, and enhanced signaling is a consequence of fibrillin-1 deficiency. Thereby, increased TGF-ß signaling may contribute to the multisystem pathogenesis of Marfan syndrome, including the development of myxomatous changes of the atrioventricular valve, aortic aneurysm and dissection, joint hypermobility syndrome. These data suggest that anti-TGF-β therapeutic strategy for patients with Marfan syndrome can be useful in prevention of the major life-threatening manifestation of this disorder.

Craniofacial Features

Aneurysms-osteoarthritis syndrome (AOS) is a recently delineated autosomal dominant disorder characterized by aneurysms, dissections, and tortuosity throughout the arterial tree in association with early onset osteoarthritis, mild craniofacial features, and skeletal and cutaneous anomalies. Previous studies have demonstrated that mutations inSMAD3, a key regulator of TGF-βsignal transduction, contribute to AOS. Here, we investigated a family of three generations affected by AOS. A novelSMAD3mutation, c.266G>A (p.C89Y), was identified and cosegregated with the affected individuals in this family. Our finding expands the mutation spectrum ofSMAD3gene and further strengthens the connection between the presence of aneurysms-osteoarthritis phenotype andSMAD3mutations, which facilitates the understanding of the genotype-phenotype correlation of AOS.

Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder that affects multiple organ systems, primarily the cardiovascular, ocular and skeletal. It is the most common inherited condition affecting the heart and the aorta, occurring in 1:5000–1:9800 people. There is no ethnic or gender predisposition; 20 to 35% of cases arise fromde novomutations.
