"[These advances are reviewed and used as the basis for a revised theory for pathogenesis: A clone of proliferating chondrocytes without functional EXT1 (or EXT2) expression fails to produce heparan sulfate; lack of heparan sulfate at the cell surface disrupts fibroblast growth factor signaling and Indian hedgehog diffusion, leading to focal overproliferation and adjacent bone collar deficiency, respectively; together these effects are proposed to contribute to osteochondroma pathogenesis.].
