Some genetic diseases can profoundly affect the quality of life of those who suffer from them. Among them, Marfan syndrome stands out as an inherited disorder that compromises the function of multiple body systems. In this article, we will explore this condition in detail, addressing its causes, symptoms and detection methods, as well as the treatment options available to improve the quality of life of patients.
What is Marfan syndrome?
Marfan syndrome is a Genetic connective tissue disease caused by a mutation in the FBN1 gene, responsible for the production of fibrillin-1, a protein crucial for tissue elasticity and strength. This pathology can affect various parts of the body, including the cardiovascular system, eyes, bones and lungs.
People with Marfan syndrome often have distinctive physical characteristics, such as long limbs, thin fingers, a sunken or prominent chest, and scoliosis. Early diagnosis and appropriate treatment are essential to prevent serious complications and improve the quality of life of those with Marfan syndrome.

View pathologies and treatmentsClassification of Marfan disease
The classification of Marfan syndrome is based on the age of onset and the severity of symptoms, and is divided into three main forms:
- Marfan Neonatal: This is the most severe and rare form, with few documented cases. It is detected at birth or even earlier by prenatal echocardiography, which can show cardiac abnormalities. Newborns have long limbs, thin fingers, loose skin, hypotonia and bone deformities, as well as cardiovascular complications. Unfortunately, in such cases, patients usually have a limited survival rate, due to the severe heart failure it causes.
- Marfan children: It manifests in early childhood with a progressive character. Children usually present skeletal and ocular alterations from an early age, and cardiovascular complications become evident over time. In addition, there may be delays in motor development and learning problems. Although the prognosis improves with early diagnosis and treatment, this form has a higher morbidity and mortality compared to the classic variant.
- Marfan Classic: This is the most common form and affects children, adolescents and adults. Symptoms progress with age and include skeletal features such as long limbs, scoliosis, chest deformity, long fingers and high-arched palate. Diagnosis of this variant is based on the Ghent criteria, which assess family history, genetic manifestations and organ or system involvement.
Causes of hereditary connective tissue disorder
Hereditary connective tissue disorders are caused by genetic mutations that affect the structure, function, or production of proteins essential for the integrity of this tissue, such as collagen, elastin, or fibrillin.
In most cases, Marfan syndrome is inherited in an autosomal dominant manner., which means that a parent with the mutation in the FBN1 gene has a 50% probability of transmitting it to their children. In other cases, the disease can arise from spontaneous mutations, that is, without a previous family history.
Symptoms of hereditary connective tissue disorder
Symptoms of Marfan syndrome may vary depending on the age and severity of the patient. The most common symptoms include:
- Skeletal system: Patients with Marfan syndrome often have disproportionately long limbs, including arms and legs, as well as thin, elongated fingers. They may also experience chest deformities, such as a sunken or prominent chest. Scoliosis is also common, as is joint hypermobility.
- Cardiovascular system: Dilatation of the aorta is one of the most serious symptoms of this disease. In addition, affected individuals may suffer from heart valve failure and arrhythmias. These cardiovascular problems can be asymptomatic for a long time, which makes early detection crucial.
- Ocular system: Patients often have visual problems such as severe myopia and lens dislocation. They are also at increased risk of retinal detachment.
- Fur: Patients may have skin that is more elastic than normal, which can cause joint hyperlaxity and increase the susceptibility to stretch marks.
How is Marfan disease detected?
The Ghent criteria are the standard used to confirm the diagnosis of Marfan disease. This approach allows for the assessment of major and minor signs in different body systems, such as skeletal, cardiovascular, and ocular. During the detailed physical examination, distinctive features such as disproportionately long limbs, scoliosis, thoracic deformities, and joint abnormalities are sought.
In addition, the genetic testing They play a crucial role in confirming the presence of mutations in the FBN1 gene, which provides a definitive diagnosis and allows for appropriate treatment planning and medical follow-up.
Common complications of inherited connective tissue disorder
Marfan syndrome can cause serious complications, especially in the cardiovascular system, such as dilation and rupture of the aorta or valvular insufficiency, which represent significant risks to life.
In the skeletal system, the disease can cause complications such as scoliosis or a sunken or prominent chest that can affect posture, mobility, or even lung and heart fusion.
At the ocular level, Marfan syndrome can present problems such as lens dislocation, severe myopia and retinal detachment.
In addition, some patients develop spontaneous pneumothorax, which causes respiratory distress. These complications require early diagnosis and appropriate medical management to prevent further risks and improve quality of life.
Diagnosis and treatment of Marfan syndrome
As we have mentioned, detecting Marfan syndrome in time is essential to implement a treatment that allows managing the serious complications associated with this disease. Treatment focuses on preventing and managing serious complications associated with this disease.Although there is no cure or way to correct connective tissue abnormalities, medical and surgical interventions can significantly improve patients' quality of life.
Medications such as beta-blockers are used to keep blood pressure down, reducing the strain on the aorta and minimising the risk of aneurysms or ruptures. Regular medical check-ups are essential to monitor the progression of the disease and detect any complications early.
In many cases, preventive intervention may be necessary to repair the affected aorta or heart valves. Additionally, depending on the area of the body involved, treatment may include braces, specific surgeries, and orthopedic corsets.
