Hypophosphatemic rickets (phosphate-diabetes) is a group of diseases associated with a defect in the reabsorption of phosphates in the proximal tubules, manifested by phosphaturia, hypophosphatemia and rickets deformities of the skeleton bones. Phosphate-diabetes has different genetic variants that determine the nature and severity of clinical manifestations. X-linked dominant hypophosphatemic rickets occurs most often (in 50–90% of cases). For the diagnosis, along with clinical characteristics, an important role is assigned to the study of partial renal functions, with the determination of clearance, excreted fraction of calcium and phosphates, as well as other indicators of calcium-phosphorus metabolism. Molecular genetic research helps to determine the form of the disease. Therapy for hypophosphatemic rickets should be differentiated depending on the type of disease. The timely appointment of an adequate pathogenetic therapy helps to slow down the formation of rickety deformities of the skeleton, positive growth dynamics, and an increase in physical activity.
Key words: hypophosphatemic rickets, children, tubulopathy.
