Autosomal dominant hypophosphatemic rickets (ADHR) is a rare disorder characterized of renal phosphate wasting and rickets/osteomalacia. ADHR is caused by mutations in a circulating peptide, fibroblast growth factor 23 (FGF23). The clinical manifestations depend on the age of patients and the importance of hypophosphatemia. In childhood, clinical manifestations are rickets with lower extremity deformities. In adult onset, it can cause osteomalacia, osteoporosis, bone pain, tiredness. ADHR displays incomplete penetrance and variability in age of onset of clinical features. Biochemical and hormonal markers of the disease are hypophosphatemia, hyperphosphaturia, increased alkaline phosphatase level and a normal level of 1,25(OH) 2D. We present the first report a baby with ADHR from Russia which one was found heterozygous for the R179Q mutation in FGF23 gene.
