Final answer:
Marfan's Syndrome is a hereditary condition that affects the connective tissue, causing abnormal growth of the extremities. It is associated with cardiovascular complications and is inherited in an autosomal dominant pattern.
Step-by-step explanation:
Marfan's Syndrome is a hereditary group of conditions of the connective tissue that causes an abnormal growth of the extremities. It is characterized by genetic defects in the protein fibrillin, which is essential for maintaining the structural integrity of connective tissue. Cardiovascular complications are common in Marfan's Syndrome, including aortic dilation and mitral valve prolapse. This condition is inherited in an autosomal dominant pattern, meaning that it can be passed on from an affected parent to their offspring.
