Development of a new mass spectrometry-based biomarker for the early and sensitive diagnosis of Gaucher Disease from blood (plasma)
Description: Next-Generation Sequencing (NGS) of the GBA gene will be performed. The mutation will be confirmed by Sanger sequencing.
Measure: Sequencing of the Gaucher disease related gene Time: 4 weeksDescription: 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.
Measure: The Gaucher disease specific biomarker candidates finding Time: 24 monthsCohort
