Step-by-step explanation:
Marfan syndrome is a genetic disorder that causes several conditions, including abnormally long digits and extremities, descending aortic aneurysm, and subluxation. The syndrome is inherited in an autosomal dominant pattern, meaning that the presence of just one faulty gene can lead to the expression of the disorder. Other genetic diseases that are inherited in a similar pattern include achondroplastic dwarfism, Huntington's disease, and certain forms of spinal muscular atrophy.
