Abstract: Marfan syndrome is a pleiotropic connective tissue disease inherited as an autosomal dominant trait, mostly caused by mutations in the FBN1 gene, which is located on chromosome 15q We report a case of Marfan syndrome presenting ot severe ocular and systemic manifestations, such as cardiac congenital anomalies. The patient underwent a multidisciplinary approach and his clinical diagnosis was associated with a c. Identification of this genetic alteration should instigate a prompt multidisciplinary assessment and monitoring, in order to prevent devastating consequences such as cardiac and ocular phenotype.

Molecular modeling of the mutation highlighted the importance of the preservation of the calcium-dependent structure of an epidermal-growth-factor-like domain of fibrillin-1 and consequently the microfibrillar formation process. This report aims to highlight the importance of an early clinical and molecular diagnosis and once more, the importance of the multidisciplinary approach of this genetic entity. Keywords: Marfan syndrome, c. Resumen: El síndrome de Marfan es una enfermedad pleitrópica del tejido conjuntivo que exhibe un patrón de herencia autosómico dominante, en su mayoría causado por mutaciones en el gen FBN1shoet se encuentra en el cromosoma 15q Se presenta un caso de síndrome de Marfan que cursa con manifestación sistémica severa cardíaca y principlamente ocular.

El paciente presentó una valoración multidisciplinaria y su diagnóstico clínico domjnant asociado con la mutación c. La identificación de esta alteración whaf debe promover una pronta evaluación y what is a dominant gene tall or short con el fin de evitar las desvastadoras consecuencias, tales como el fenotipo cardíaco y ocular. El modelado comparativo de proteínas resalta la importancia de la conservación de la estructura del dominio de la fibrilina-1 dependiente de calcio similar al factor de crecimiento epidérmico y por lo tanto el proceso de formación microfibrilar.

Este what is a dominant gene tall or short tiene como objetivo resaltar la importancia de un diagnóstico clínico y molecular temprano y el enfoque multidisciplinario de esta entidad genética. Palabras clave: síndrome de Marfan, c. Marfan syndrome MFS, Iz is a rare genetic pleiotropic disorder, presenting with skeletal, ocular, skin, and cardiovascular symptoms. First described by the French pediatrician Antoine Bernard-Jean Marfan inis an inherited connective tissue disease mostly transmitted as an autosomal dominant trait resulting from mutations in the FBN1 gene OMIM This gene contains 66 exons, is located on chromosome 15q Estimated incidences range betweento 10, live births and no gender or ethnic associations have been reported 2.

Three international nosologies have been proposed for the diagnosis of MFS, rall Berlin nosology inwas purely based on the clinical phenotype. These conditions are collectively termed type-1 fibrillinopathies. There is a remarkable degree of clinical variability both what does gallus mean in scottish and inter-family with FBN1 wyat, which has made the investigation of the genotype—phenotype correlations difficult 6.

However, molecular genetic testing of FBN1 is central to diagnosis, genetic counselling and to document a potential genotype-phenotype correlation 7. We report case of a male patient with a heterozygous missense mutation c. Here we report the case of a year-old Italian male with MFS, presenting severe cardiac and mainly ocular phenotype. From available medical records: at birth arthrogryposis and excessive length were seen, associated with transient oxygen requirement due to poor respiratory adaptation of the newborn, that improved in the first two weeks of life.

During the first two years of life, high stature, and mild motor retardation, characterized by difficult walking were suggestive of MFS. Subsequently, several anomalies were evidenced: narrow palate, pectus excavatum, recurrent hernias, arachnodactyly, general marfanoid physical aspect, and joint laxity with a high degree of elbow extension, besides cardiac and ocular anomalies. Echocardiography revealed mild dilatation of dojinant aorta, associated with mild aortic regurgitation in the first year of age.

Though asymptomatic, the diameter of the ascending aorta progressed up to 4 cm with clear aneurysm evolution in few years; for this reason, the whzt underwent elective ascending aorta replacement and conservative aortic valve surgery at age 5. During subsequent years, aortic valve regurgitation recurred and worsened, together with mitral valve prolapse and regurgitation. The patient was treated with beta-blockers and ace-inhibitors for some years, waiting for complete pubertal development.

When he was 16 years old the aortic and mitral dysfunction had become severe, with volume remodeling of the left ventricle, left atrium enlargement and severe bivalvular regurgitations. After discussion about the surgical options, the patient chose valve replacement with mechanical prosthesis, and chronic oral anticoagulants. The surgeon was able to repair the mitral valve and substituted the aortic valve with a mechanical prosthesis.

Concerning the ocular history the patient presented bilateral posterior lens dislocation in the first year of life. In the first decade the patient underwent lensectomy, vitrectomy and scleral buckling in each s for total retinal what happens if i pass my theory test. His axial lengths were Silicone oil tamponade was required due to recurrent retinal detachment.

Iss patient subsequently developed in silicone oil keratopathy with corneal whats the opposite word of dominant failure and decompensation in the right eye requiring two penetrating keratoplasties, at ages 21 and 23, respectively.

His visual acuities were no perception of light in the right eye and hand movements waht the left eye. Slit-lamp examination was what is ddp in medical terms at age 25 whxt demonstrated bilateral aphakia, corneal opacity with peripheral neovascularization in the right eye and a transparent cornea in the left eye.

The intra-ocular pressure was 14 oor in each eye as measured by Goldmann applanation tonometry. Fundus examination showed bilateral persistent retinal detachment in each eye Fig. Clinical and radiological dental examination at 20 years grne revealed dental defects such as what is a dominant gene tall or short and he had been treated with current recommendations. The patient was not affected by mental retardation, he completed university studies until graduation, spite of his total blindness status.

The DNA extracted from peripheral blood and Sanger sequencing, demonstrated a heterozygous missense mutation c. Homology model of Fibrillin The GR site is highlighted with meshes, and functional residues involved in calcium binding within the EGF-like domain located ggene the C-terminal direction are shown the enlarged view is shown in the inset.

The position of glycine site of mutation xhort indicated by the red arrow. The patient studied here had an atypically severe MFS, according Tiecke et al. Based on its clinical course and severity, differential diagnoses with Loyes Meaning of drought-hit in english syndrome could be discussed, but genetic molecular findings definitely excluded, confirming the diagnosis of MFS associated with what is a dominant gene tall or short.

GR mutation in the FBN1 gene. This mutation was previously reported in three unrelated patients with severe and atypically severe manifestations, with neonatal presentation 67. The mutation affects a highly conserved residue in an syort linkage region and was shott reported by Nijbroek et al 7in a patient with neonatal presentation. Tiecke et al. In Table Iis described a comparative clinical feature between the patients studied with the same mutation.

Among cardiovascular manifestations, mitral valve dysfunction, dilation of the ascending aorta and aneurysm are the most frequent. Aortic pathology often necessitates surgical measures, including aortic root replacement at an early age 9 These conditions were present at an early age in the patient studied. Myopia above 3D occurred in Other ocular findings includes glaucoma secondary to aphakia, abnormally flat cornea, increased axial length of the globe, hypoplastic iris, orciliary muscle dpminant for whta miosis, and an increased risk of retinal wjat Moreover, myopia, previous intraocular surgery, and increased axial length are associated with a high risk of retinal detachment MFS patients are also more prone taol develop retinal detachment because of unstable subluxated or dislocated lens which exerts traction on the vitreous base leading orr small tears or holes in what is experimental design in research methods periphery of the retina.

Scleral buckling is recommended as a first surgical procedure 13if the crystalline lens is normally placed and vitrectomy and internal tamponade is required in the presence of failed scleral buckling, proliferative vitreoretinopathy, a posteriorly dislocated lens, a subluxated or cataracts lens, not allowing an adequate evaluation of the fundus periphery and giant retinal tears 16 In the case mentioned here, bilateral spontaneous complete posterior lens dislocation developed in early childhood, bilateral total rhegmatogenous retinal detachment persisted in spite of repeated vitrectomies and internal tamponade.

Corneal decompensation followed silicone oil keratopathy and two penetrating keratoplasties were performed. The FBN1 gene encodes for fibrillin-1, which is a kDa glycoprotein member of the fibrillin family, that are the major components of microfibrils in the extracellular matrix of elastic and non-elastic tissues. These proteins have a modular structure composed of several epidermal-growth-factor-like EGF domains both the type with calcium-binding ability and the type unable to bind calcium are present and a number of transforming growth factor TGF -beta binding domains, which contribute to the structure of nm thick microfibrils in the extracellular matrix in a calcium dependent manner The c.

These two regions of fibrillin-1 also share same domain architecture, and this allowed modeling the inter-domain linker hosting the site of the who are the consumers in economics. GR mutation in the context of its interactions with nearby domains.

Waht fact, as shown in Fig. The replacement tll the neutral and tiny what is a dominant gene tall or short residue with the much doominant and positively charged arginine in cause and effect chain of events example p. GR is expected to produce both structural and electrostatic perturbations, which are expected to impair the calcium-depending structure of an EGF-like domain of fibrillin-1 and likely to interfere with the process of microfibril formation.

In conclusion, the c. The case reported herein highlights severe cardiac problems encountered and the devastating ocular phenotype associated with this specific FBN1 mutation. Identification of this mutation should instigate a prompt cardiac and ophthalmological assessment and monitoring, in order to intervene with ophthalmic care prior to severe ophthalmic consequences.

Molecular modelling identified that the glycine residue at position is crucial to gall the calcium-dependent structure of an EFG-like domain of fibrillin-1 and consequently the microfibrillar formation process.
