Chimeric CYP21A1P/CYP21A2 genes identified in Czech patients with congenital adrenal hyperplasia.

Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by an enzymatic deficiency which impairs the biosynthesis of cortisol and, in the majority of severe cases, also the biosynthesis of aldosterone. Approximately 95% of all CAH cases are caused by mutations in the steroid 21-hydroxylase gene (CYP21A2). The CYP21A2 gene and its inactive pseudogene (CYP21A1P) are located within the HLA class III region of the major histocompatibility complex (MHC) locus on chromosome 6p21.

[Molecular analysis of Wilson disease].

Background: Wilson disease is an autosomal recessive disorder, characterized by cooper accumulation and intoxication of the organism. Molecular basis of the disease represent mutations in the gene for the copper-transporting ATPase (ATP7B).

Methods And Results: The submitted paper deals with results of molecular-genetic examination in 130 unrelated families in which Wilson disease was diagnosed.

Screening of the most common medium-chain acyl CoA dehydrogenase (MCAD) deficiency mutation (K329E) in the Czech newborn population.

Medium chain acyl-CoA dehydrogenase (MCAD) deficiency is the commonest inherited disorder of fatty acid oxidation. Most clinically ascertained cases are caused by thc point mutation K329E in MCAD gene. The frequency of this mutation as determined by usc of dried blood spots on Guthrie cards and the PCR NeoI digestion method.

[The hepatic form of Wilson's disease in young patients].

Unlabelled: Wilson's disease (WD) is a hereditary disorder of the copper metabolism with very varied clinical and biochemical symptoms. Hepatic and neurological forms are the most frequent manifestations of this rare disease. In schoolchildren and adolescents symptoms of liver damage predominate.
