Osteoporosis/renal Osteodystrophy

Osteoporosis is the loss in bone mineral density that results in a more frequent ocurrence of fractures.

Test Strategy

The current genetic parameters of osteoporosis can only help to estimate the risk but not the cause. Thats why the genetic testing should be considered early in the diagnostic process.

Pathogenesis

Osteoporosis develops when osteoclasic processes dominate over osteoblastic processes. Osteoporosis is a frequent disease thats why the undelying genetic disturbances must be frequent too. A lot of genes involved in bone metabolism are possible candidates responsible for osteoporosis. Association of mutations in some of these genes and osteoporosis has been established but the link between genetic disturbance and real disease is not well clarifyed yet.
