Background: Nonclassical congenital adrenal hyperplasia (NCCAH) due to mild 21-hydroxylase deficiency is caused by mutations of the CYP21A2 gene located on chromosome 6p21.3.Objective and hypotheses: To determine cut-off for basal and stimulated 17-hydroxyprogesterone (17-OHP) levels, to evaluate CYP21A2 gene mutations frequency among Croatian NCCAH patients, to determine correlation between 17-OHP levels and genotype and to evaluate co...

Background: Congenital adrenal hyperplasia (CAH) due to 11β-hydroxylase deficiency (11OHD), a rare autosomal recessive disorder, is the second most common form of CAH, resulting in glucocorticoid deficiency, hyperandrogenism and hypertension.Objective and hypotheses: To investigate the specific CAH mutations in CYP11B1 gene and to examine for genotype-phenotype correlations.Method: 21 patients (n=9, 46, XX; <...
