| Popis: | Heterozygosity forCYP21A2mutations in females is possibly related to increased risk of developing clinical hyperandrogenism. The present study was designed to seek evidence on the phenotype-genotype correlation in female children, adolescents, and women withCYP21A2mutations and variants in the 3′UTR region of the gene. Sixty-six patients out of the 169 were identified as carriers ofCYP21A2mutations. Higher values of stimulated 17 hydroxyprogesterone (17-OHP) levels were found in the carriers of the p.Val281Leu mutation compared to the carriers of other mutations (mean: 24.7 nmol/l versus 15.6 nmol/l). The haplotype of the∗52C>T,∗440C>T, and∗443T>C in the 3′UTR was identical in all heterozygous patients with p.Val281Leu and the haplotype of the∗12C>T and∗52C>T was identical in all heterozygous patients with the p.Gln318∗. In conclusion, hyperandrogenaemic females are likely to bear heterozygousCYP21A2mutations. Carriers of the mild p.Val281Leu mutation are at higher risk of developing hyperandrogenism than the carriers of more severe mutations. The identification of variants in the 3′UTR ofCYP21A2in combination with the heterozygous mutation may be associated with the mild form of nonclassic congenital adrenal hyperplasia and reveal the importance of analyzing theCYP21A2untranslated regions for the appropriate management of this category of patients. |
