متن کاملHigh-Dose Hook Effect in 17-Hydroxyprogesterone Assay in a Patient with 21-Hydroxylase Deficiency.
Congenital adrenal hyperplasia (CAH) describes a group of disorders characterized by enzyme defects in adrenal steroidogenesis. 21-hydroxylase deficiency (21-OHD) is the most commonly encountered form. The analysis of steroids in pediatric cases requires high-sensitivity assays. A 14-year-old Syrian girl was referred for evaluation of short stature, amenorrhea, and hirsutism. On physical examin...
متن کاملEarly Diagnosis of Children with Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency by Newborn Screening
Congenital adrenal hyperplasia (CAH) comprises a group of rare autosomal recessively inherited disorders of cortisol biosynthesis in the adrenal cortex. More than 95% are based on a defect in the CYP21A2 gene causing 21-hydroxylase deficiency. Newborn screening (NBS) for CAH by means of 17-hydroxy-progesterone (17-OHP) determination in dried whole blood on filter paper has been introduced as pa...
متن کاملNeonatal mass screening for 21-hydroxylase deficiency.
Congenital adrenal hyperplasia(CAH)due to 21-hydroxylase deficiency (21-OHD) is an inherited autosomal recessive disorder. Its incidence is 1 in 10,000 to 20,000 worldwide. This disease shows phenotypic differences, and it is divided into three forms i.e., the salt wasting (SW), simple virilizing (SV), and nonclassic (NC) forms. The most severe form of SW manifests in the first months of life w...
متن کاملA Case of Bilateral Testicular Tumors Subsequently Diagnosed as Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency
21-hydroxylase deficiency (21-OHD) caused congenital adrenal hyperplasia (CAH) is a group of autosomal recessive genetic disorders resulting from mutations in genes involved with cortisol (CO) synthesis in the adrenal glands. Testicular adrenal rest tumors (TARTs) are rarely the presenting symptoms of CAH. Here, we describe a case of simple virilizing CAH with TARTs, in a 15-year-old boy. The p...
