Marfan syndrome: diagnosis, causes, and consequences

Description of Marfan Syndrome

Marfan syndrome is a genetic disorder that affects connective tissues, caused by a mutation in the fibrillin-1 gene. The main characteristics of the syndrome include a tall and slender build, disproportionate limb length compared to the torso, a narrow chest, and long fingers. Patients also often face heart problems, including aneurysms and valve defects, as well as issues with the eyes, joints, and skin.

A key aspect of managing Marfan syndrome is monitoring cardiovascular status and timely correction of abnormalities. Treatment includes pharmacotherapy, surgical intervention in case of serious complications, and regular consultations with a genetic counselor for family planning and preventing hereditary transmission of the disorder.

Factors in the development of Marfan syndrome

Marfan syndrome is a genetic disorder caused by a mutation in the FBN1 gene, which encodes the protein fibrillin-1, playing a crucial role in the structure of connective tissue. A mutation in this gene leads to a disruption in the structure and function of connective tissue, manifesting in various symptoms characteristic of the syndrome, including a tall stature, long limbs, and other signs.

A distinctive feature of Marfan syndrome is its heredity, with the condition being transmitted in most cases through a dominant inheritance pattern. This means that one healthy parent with a mutation in the FBN1 gene can pass it on to their offspring. Additionally, in rare cases, a mutation can occur in a person without a family history, resulting from new mutations in gametes or sperm at conception.

  • Mutation of the FBN1 gene: The main cause of Marfan syndrome is the presence of a mutation in the FBN1 gene, responsible for the synthesis of the protein fibrillin-1, which is necessary for the normal structure of connective tissue.
  • Inheritance: Marfan syndrome is most often inherited from one of the parents, which is related to the dominant mode of inheritance. New mutations in the FBN1 gene can also lead to the development of the syndrome.
  • Connective tissue disorders: Changes in the structure and function of connective tissue lead to a tall stature, long limbs, and other characteristic symptoms of Marfan syndrome.
  • Environmental influence: Some environmental factors, such as exposure to certain chemicals or radiation, may affect the occurrence of mutations in the FBN1 gene, contributing to the development of the syndrome.
  • Medical features: Some medical procedures or conditions, such as prolonged treatment with glucocorticoids, may increase the risk of developing Marfan syndrome in some individuals.

Manifestations of Marfan Syndrome

Marfan syndrome is characterized by a variety of clinical manifestations, including long, thin limbs, long fingers (arachnodactyly), an elongated body shape, facial features (dolichocephaly, microsomia), chest deformity (sunken or protruding chest), scoliosis, tall stature, heart and vascular abnormalities (such as aortic dilation, valve defects), vision problems, including strabismus and retinal detachments, as well as a high risk of developing aneurysms and lens dislocation.

Other common symptoms of Marfan syndrome include joint laxity, long fingers (arachnodactyly), hypermobility, blood clotting ability, and skin extensibility. This combination of symptoms can present to varying degrees and be combined in different patients, making the diagnosis and treatment of Marfan syndrome a challenge for medical professionals.
