Abstract
Mutations in colony stimulating factor 1 receptor (CSF1R) result in CSF1R-related disorder (CSF1R-RD). Our previous study demonstrated a proteolytic generation of a soluble CSF1R (sCSF1R) that could potentially serve as a diagnostic biomarker of CSF1R-RD. Herein, we observed that sCSF1R is released into peripheral serum as a highly glycosylated monomer in Csf1r<sup>+/-</sup> mice that mimic the clinical symptoms of CSF1R-RD patients. Notably, we found that serum sCSF1R could distinguish CSF1R-RD cohorts from controls with high accuracy as evaluated by receiver operating characteristic (ROC) curves. This study demonstrates that reduced sCSF1R in serum may serve as a diagnostic biomarker for CSF1R-RD. ANN NEUROL 2025;97:397-403.
