One example of a disorder of connective tissue is Ehlers-Danlos syndrome, which is a group of genetic disorders that affect the body's ability to produce collagen, a key protein in connective tissue. This can lead to symptoms such as joint hypermobility, skin hyperextensibility, and fragile blood vessels. Other examples of connective tissue disorders include Marfan syndrome, osteogenesis imperfecta, and systemic lupus erythematosus.
