Follow-up study of Gambian children with rickets-like bone deformities and elevated plasma FGF23: Possible aetiological factors

► Low dietary calcium and eGFR in Gambian children with a history of rickets. ► High FGF23 and urinary phosphate loss in Gambian children with a history of rickets. ► Supports the calcium deficiency hypothesis as the aetiology of Gambian rickets. ► Iron status may be involved in FGF23 metabolic pathways.
