Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Active PDB is defined as elevated biochemical markers of bone turnover in the form of serum alkaline phosphatase (ALP) activity (in the presence of normal serum γGT), and/or elevated serum P1NP values, in addition to localised increased radioactive isotope uptake on Tc-99m skeletal scintigraphy. Therefore in all subjects with ALP and or P1NP levels above the upper limit of normal, a skeletal scintigram will be performed and if abnormal X-rays will be performed. In subjects harbouring the SQSTM1 gene mutations or skeletal complaints or a history of bisphosphonate use without increased bone formation markers radiological assessment will be performed as well to exclude active PDB. | — |
Secondary
| Measure | Time frame |
|---|---|
| Relationship between the presence of a SQSTM1 mutation and the development of clinical, biochemical and scintigraphic features of PDB In non-carieres new mutation analyses will be performed. | — |
