FGFR3 Inhibition in SLC26A2 Chondrodysplasia
2026-09-12
A Journal of Orthopaedic Translation study combined genetic models, inducible chondrocyte deletion, cell assays, and pharmacological intervention to test whether excessive FGFR3 signaling contributes to SLC26A2-related chondrodysplasia. The findings support FGFR3 pathway inhibition as a preclinical strategy that can improve chondrocyte behavior and aspects of skeletal development, while also defining important limits for translation to human disease.
