What type of condition is characterized by a protruding sternum and long limbs?

1. Osteogenesis imperfecta

2. Marfan syndrome

3. Achondroplasia

4. Ehlers-Danlos syndrome

The correct answer is: Marfan syndrome

Marfan syndrome is characterized by a variety of symptoms that often include a protruding sternum and long limbs. This genetic disorder affects the body's connective tissue, leading to changes in skeletal development. Individuals with Marfan syndrome typically have long fingers and limbs, a tall stature, and may prominently exhibit a deformity known as pectus excavatum or pectus carinatum, which manifests as a protrusion of the sternum. The underlying connective tissue abnormalities in Marfan syndrome also impact cardiovascular health, eyes, and other systems, but the skeletal features are among the most recognizable characteristics. Given the question's emphasis on the specific physical traits of a protruding sternum and elongated limbs, Marfan syndrome accurately fits this description due to its distinctive impact on the skeletal structure.
