Patients with Hypophosphatasia disease or high-grade suspicion for Hypophosphatasia disease

Primary Outcome Measures :
  1. Sequencing of the Hypophosphatasia disease related gene [ Time Frame: 4 weeks ]
    Next-Generation Sequencing (NGS) of the ALPL gene will be performed. The mutation will be confirmed by Sanger sequencing.

Secondary Outcome Measures :
  1. The Hypophosphatasia disease specific biomarker candidates finding [ Time Frame: 24 months ]
    The quantitative determination of small molecules (molecular weight 150-700 kD, given as ng/μl) within a dried blood spot sample will be validated via liquid chromatography multiple reaction-monitoring mass spectrometry (LC/MRM-MS) and compared with a merged control cohort. The statistically best validated molecule will be considered as a disease specific biomarker.

Biospecimen Retention:   Samples With DNA
For the development of the new biomarkers using the technique of Mass-spectrometry 7, 5 ml EDTA blood and a dry blood spot filter card are taken. To proof the correct di- agnosis of Hypophosphatasia in those patients where up to the enrollment in the study no genetic testing has been done, sequencing of Hypophosphatasia disease will be done. The analyses will be done at the: Centogene AG Am Strande 7 18055 Rostock Germany
