[Updates on rickets and osteomalacia: FGF23-mediated hypophosphatemic rickets/osteomalacia].
Some of the hypophosphatemic rickets/osteomalacia are caused by the increased bioactivity of FGF23, and classified into FGF23-mediated hypophosphatemic rickets/osteomalacia. This group includes various disorders such as X-linked, autosomal dominant and autosomal recessive hypophosphatemic rickets/osteomalacia, tumor-induced osteomalacia, and rickets/osteomalacia caused by the administration of iron polymaltose or saccharated ferric oxide. Measurement of serum levels of FGF23 is useful for diagnosis of these conditions. In the adult patients with FGF23-mediated hypophosphatemic rickets/osteomalacia, mineralizing enthesoopathy is an often observed complication.
