It is a rare late stage bone sequelae of long standing hyperparathyroidism. Parathyroid adenoma is the commonest cause of primary hyperparathyroidism.We present a referred case of 15-year-old girl with highly aggressive...

Background & Aim: Vitamin D-dependent rickets type 1 A (VDDR1A) is an autosomal recessive condition caused by mutation in CYP27B1, which encodes 1 α-hydroxylase enzyme that catalyzes the conversion of 25-hydroxyvitamin D (25OHD) to 1,25-dihydroxyvitamin D (1,25 (OH)2D). We are reporting 4 cases of VDDR1A due to CYP27B1 mutation initially misdiagnosed as vitamin D deficient and hypophosphatemic rickets.<p class="abstext...
