Overview
The authors present case reports of three children suffering from 21-hydoxylase deficiency due to p.I173//CYP21A1P/CYP21A2 chimeric gene genotype. Case reports document the improvement of health and final height due to early diagnosis and treatment through neonatal screening and the phenotype variability of p.I173N mutation. Key words: 21-hydroxylase deficiency, neonatal screening, phenotype, puberty
