Which type of osteoporosis is characterized by bone fragility due to a genetic condition?

• A. Primary osteoporosis
• B. Secondary osteoporosis
• C. Osteogenesis imperfecta
• D. Idiopathic juvenile osteoporosis

Answer: (C)

The correct choice identifies osteogenesis imperfecta as the type of osteoporosis characterized by bone fragility due to a genetic condition. Osteogenesis imperfecta is a genetic disorder that affects the body's ability to produce strong bones, leading to a higher risk of fractures and fragility. This condition is caused by mutations in genes responsible for collagen production, specifically type I collagen, which is essential for bone strength and structure. In contrast, primary osteoporosis typically occurs due to age-related changes and hormonal factors, while secondary osteoporosis results from specific medical conditions or medications that adversely affect bone density. Idiopathic juvenile osteoporosis involves bone density loss in children without a known cause, but it is not strictly categorized as a genetic condition like osteogenesis imperfecta. Understanding these distinctions clarifies why osteogenesis imperfecta is specifically recognized for its genetic basis leading to bone fragility.
