Phenotype & genotype of congenital adrenal hyperplasia due to mutation in the type ii 3β-hydroxysteroid dehydrogenase gene: a report of two Vietnamese families
Congenital adrenal hyperplasia (CAH) is one of the most common inherited metabolic disorders. It includes a group of autosomal recessive disorders caused by the deficiency of one of the enzymes involed in one of the various steps of adrenal steroid synthesis. 3b-Hydroxysteroid dehydrogenase (3b-HSD) deficiency is a rare cause of CAH caused by inactivating mutations in the HSD3B2 gene. Most muta...
متن کاملIsolation of a New Mouse 3β-Hydroxysteroid Dehydrogenase Isoform, 3β-HSD VI, Expressed During Early Pregnancy.
The enzyme 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is a key enzyme in the biosynthesis of steroid hormones. To date, this laboratory has isolated and characterized five distinct 3beta-HSD complementary DNAs (cDNAs) in the mouse (3beta-HSD I through V). These different forms are expressed in a tissue- and developmentally-specific manner and fall into two functionally distinct enzymes. 3be...
متن کاملUniparental Isodisomy of Chromosome 1 Unmasking an Autosomal Recessive 3-Beta Hydroxysteroid Dehydrogenase Type II-Related Congenital Adrenal Hyperplasia
Steroid 3-beta hydroxysteroid dehydrogenase type II (3β-HSD2) deficiency is a rare autosomal recessive form of congenital adrenal hyperplasia (CAH). We report the genetic basis of 3β-HSD2 deficiency arising from uniparental isodisomy (UPD) of chromosome 1. We describe a term undervirilized male whose newborn screen indicated borderline CAH. The patient presented on the 7th day of life in salt-w...
متن کاملMutation of 3β-hydroxysteroid dehydrogenase (3β-HSD) at the 3'-untranslated region is associated with adrenocortical insufficiency.
In the present study, we report the mutation of the 3β-hydroxysteroid dehydrogenase (3β-HSD) gene in a family suffering from adrenocortical insufficiency. The index patient was clinically diagnosed with adrenocortical insufficiency. Peripheral venous blood (5 ml) was collected from the proband and 5 members of his family, and genomic DNA was extra...
متن کامل3β-hydroxysteroid dehydrogenase type II deficiency on newborn screening test.
3β-hydroxysteroid dehydrogenase II (3β-HSD) deficiency represents a rare CAH variant. Newborns affected with its classic form have salt wasting in early infancy and genital ambiguity in both sexes. High levels of 17-hydroxypregnenolone (Δ517OHP) are characteristic, but extra-adrenal conversion to 17-hydroxyprogesterone (17OHP) may lead to positive results on newborn screening tests.
