Background: Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by defects in one of the several adrenal steroidogenic enzymes. 80–95% of CAH are due to mutations in CYP21A2 gene encoding 21 hydroxylase. Its residual activity defines the clinical form. Except deletions and large gene conversions, nine pseudogene-derived mutations are responsible for 95% of all CAH alleles. The mutational distribution varies between diffe...

Background: Congenital adrenal hyperplasia (CAH) is a group of inborn errors of steroidogenesis. It is mainly caused by steroid 21-hydroxylase coding gene (CYP21A2) mutations. More than 30% of the CYP21A2 mutations are deletions, with ethnic specific differences. The Bulgarian mutational spectrum of CYP21A2 gene is unknown.Objective and hypotheses: To determine CYP21A2 mutation spectrum in Bulgarian CAH patients.<p...

Methodological Considerations into the Approach for Genetic Diagnostics of Congenital Adrenal Hyperplasia in a Girl with SW Form and Relatively Higher Needs of Mineral Corticoids

Dineva Ganka , Stoeva Iva , Kirov Andrey , Todorova Albena , Iliev Daniel , Kaleva Narcis , Grozdanova L

Background: 80–95% of congenital adrenal hyperplasia (CAH) cases are due to mutations in the CYP21A2 gene encoding 21 hydroxylase. The residual activity of the gene defines the clinical form. Routine mutational screening of CYP21A2 defects is shown to effectively support the complex diagnostic and treatment procedure of newborns with CAH.Objective: We aimed to characterise the phenotype of a girl with compound heterozygosity of ...
