Question

Quizplus · Accepted Answer

Erica's symptoms point towards a segmental progeroid syndrome, which is a genetic disorder that causes premature aging in specific regions of the body. This is different from general progeria, which affects the entire body. Werner syndrome, while also causing premature aging, typically presents with additional symptoms not mentioned in Erica's case. Alzheimer's disease and clotting disorders are not known to cause premature aging, and while osteogenesis imperfecta can result in thin bones and short stature, it does not typically cause premature aging either.
