Background: In adrenal gland 3β-HSD2 catalyses the conversion of Δ5 to Δ4 steroids (i.e., pregnenolone to progesterone,17 α-hydroxypregnenolone to 17-OHP and DHEA to androstenedione). Defect in this enzyme can affect glucocorticoid, mineralocorticoids and sex steroid synthesis but the clinical and biochemical profile can be very complicating and confusing due to conversion of intermediate steroids to more ac...

Background: Hypomagnesemia type 1 (HOMG1) is a rare autosomal recessive condition due to TRPM6 mutation, leading to decrease intestinal magnesium absorption.Objective: To determine the clinical spectrum of HOMG1 due to TRPM6 mutation at a tertiary centre.Case Series: Seven patients (all male) from six different families of hypomagnesemia type 1 due to homozygous TRPM6 mut...

Background & Aim: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is an autosomal recessive condition characterized by inadequate production of cortisol and aldosterone and accumulation of androgens. Beta thalassemia is an autosomal recessive condition caused by defective beta-globin resulting in accumulation of unbound alpha globin chains leading to ineffective erythropoiesis. We are reporting an unusual case of CAH due to 21-hydroxy...

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...
