Özet

Rickets is a group of diseases characterized by reduced mineralization of bone matrix in growing children. Although the most common cause is nutritional vitamin D deficiency, it may also appear as the result of hereditary diseases. Vitamin D-dependent rickets type I arises due to an autosomal recessive disturbance in renal 1 a-hydroxylase enzyme which converts 25(OH)D to 1,25(OH)2D. This condition is also called as pseudovitamin D deficiency. 25(OH)D level is normal but 1,25(OH) 2D level low. In this study, clinical and laboratory features of two cases aged 15 months and 2 years who were brought to Pediatric Endocrinology Clinic with different complaints and diagnosed with vitamin D-dependent rickets type I are presented and discussed.
