Introduction: Systematic newborn screening (NBS) based on 17 ɑ OHP, followed by molecular analysis for the most frequent adrenal enzyme steroid abnormalities in newborns at high risk for congenital adrenal hyperplasia (CAH), allowed to reveal the nature of genotype-phenotype correlations in most of the patients (pts) presented as “classical CAH” – salt wasters (SW) or simple virilizers (SV). According to the enzyme rest activity they co...

The CYP21A2 and the TNXB genes are highly homologous with their corresponding pseudogenes (CYP21A1P and TNXA), leading to frequent homologous recombination. The TNXB includes 43 exons, the mRNA encodes tenascin-X (TNX), an extracellular matrix glycoprotein, highly expressed in connective tissue.CAH patients with a "contiguous gene syndrome" comprising a deletion of both genes- CYP21A2 and TNXB have been described. Chimeric genes generated by larg...
