Introduction to Marfan-like Syndrome
Marfan-like syndrome, also known as Marfanoid syndrome, is a connective tissue disorder characterized by systemic manifestations affecting various body systems. This genetic condition follows an autosomal dominant inheritance pattern, meaning a single copy of the mutated gene is enough to cause the disorder. Individuals with Marfan-like syndrome may experience a wide range of symptoms, including skeletal abnormalities, tall stature, arachnodactyly (long, slender fingers), pectus excavatum (sunken chest), kyphosis (curvature of the spine), and scoliosis (sideways curvature of the spine).
In addition to these skeletal features, Marfan-like syndrome can also present with ocular manifestations such as lens dislocation, cardiovascular complications like mitral valve prolapse, aortic aneurysm, and aortic dissection, as well as dural ectasia (enlargement of the dural sac surrounding the spinal cord). The complexity of this condition requires a comprehensive understanding of its clinical features and potential complications to provide appropriate diagnosis and management strategies.
Through this article, we aim to delve into the intricate details of Marfan-like syndrome, shedding light on its genetic basis, diverse clinical features, skeletal abnormalities, ocular manifestations, cardiovascular complications, systemic manifestations, as well as the crucial aspects of diagnosis and management.
