http://purl.uniprot.org/citations/12915679 | http://www.w3.org/2000/01/rdf-schema#comment | "Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive disorders. The aim of this study was to assess the frequencies of CYP21 mutations and to study genotype-phenotype correlation in a large population of Dutch 21-hydroxylase deficient patients. From 198 patients with 21-hydroxylase deficiency, 370 unrelated alleles were studied. Gene deletion/conversion was present in 118 of the 370 alleles (31.9%). The most frequent point mutations were I2G (28.1%) and I172N (12.4%). Clustering of pseudogene-derived mutations in exons 7 and 8 (V281L-F306 + 1nt-Q318X-R356W) on a single allele was found in seven unrelated alleles (1.9%). This cluster had been reported before in two other Dutch patients and in two patients in a study from New York, but not in other series worldwide. Six novel mutations were found: 995-996insA, 1123delC, G291R, S301Y, Y376X, and R483Q. Genotype-phenotype correlation (in 87 well documented patients) showed that 28 of 29 (97%) patients with two null mutations and 23 of 24 (96%) patients with mutation I2G (homozygous or heterozygous with a null mutation) had classic salt wasting. Patients with mutation I172N (homozygous or heterozygous with a null or I2G mutation) had salt wasting (2 of 17, 12%), simple virilizing (10 of 17, 59%), or nonclassic CAH (5 of 17, 29%). All six patients with mutation P30L, V281L, or P453S (homozygous or compound heterozygous) had nonclassic CAH. The frequency of CYP21 mutations and the genotype-phenotype correlation in 21-hydroxylase deficient patients in The Netherlands show in general high concordance with previous reports from other Western European countries. However, a cluster of four pseudogene-derived point mutations on exons 7 and 8 on a single allele, observed in almost 2% of the unrelated alleles, seems to be particular for the Dutch population and six novel CYP21 gene mutations were found."xsd:string |
