Genetic variation at PPM1H predicts mobilization efficiency in stem cell donors
La, Y. P., Torres Di Bello, D., Mahecha Escobar, M. L., Cafaro, C., Wichert, S., Lopez de Lapuente Portilla, A., & Nilsson, B. (2025). Genetic variation at PPM1H predicts mobilization efficiency in stem cell donors. Blood Advances, bloodadvances-2024015246.
From the text: “We now find an association between the PPM1H–low-expressing rs772557-A allele and a greater increase in blood CD34+ cell levels upon G-CSF mobilization therapy in a prospective series of consecutively recruited allogeneic stem cell donors. Our results provide additional genetic support for PPM1H as a potential inhibition target to facilitate CD34+ cell mobilization”
