Prenatal diagnosis and treatment of congenital adrenal hyperplasia due to steroid 21-hydroxylase (21-OH) deficiency has been proved to be effective. Screening for a panel of nine point mutations, deletions, and gene conversions allows the identification of most of the mutations, although 6-12 per ce

The frequency of 12 different mutations of the steroid 21-hydroxylase gene (CYP21) was investigated in 129 French patients affected by congenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase deficiency. Eighty-nine percent of the CAH chromosomes were characterized. The most frequent mutat
We have investigated 68 unrelated 21-hydroxylase deficient Danish patients, representing 136 alleles, and determined the mutational spectrum of the CYP21 gene. The most frequent mutations detected were deletion of CYP21 and the splice mutation in intron 2 (I2-splice). Segregation analysis showed evi
We describe a steroid 21-hydroxylase allele carrying four disease-causing mutations, viz. I173N, V282L, I237N + V238E + M240K, and the insertion of T at 308 L. The first two are established causes of partial enzyme deficiency, whereas the last two are known to result in the most severe, salt-wasting
