[Congenital adrenal hyperplasia due to 11ß-hydroxylase deficiency: late diagnosis and gender reassignment in a two-year-old child].

11ß-hydroxylase deficiency is a rare autosomal recessive disorder due to impaired steroidogenesis in the adrenal cortex caused by pathogenic mutations in the CYP11B1 gene. The main clinical manifestations are determined by a deficiency of cortisol, ACTH hyperproduction, excessive androgens secretion and the accumulation of 11-deoxycorticosterone, which leads to the development of arterial hypertension. In the diagnostic search, it is important to take into account the ethnicity of the patient, since the frequency of the disease and the prevalence of mutations differ between ethnic groups. The article presents a clinical case of 11ß-hydroxylase deficiency as the result of compound heterozygous mutations in the CYP11B1 gene in a patient of Turkic origin. This case shows the clinical manifestations and the development of complications of 11ß-hydroxylase deficiency, the stages of differential diagnosis of patients with 21-hydroxylase deficiency.

n the article some corrections were needed. Abstract: "Heterozygous SF1 variants were found in 36 out of 310 (11.6%) of cases, among them 15 were not previously described". has been corrected to read "Heterozygous SF1 variants were found in 36 out of 310 (11.6%) of cases, among them 22 were not previously described". Results: "Heterozygous SF1 variants were found in 36 out of 310 (11.6%) of cases, among them 15 were not previously described", has been corrected to read "Heterozygous SF1 variants were found in 36 out of 310 (11.6%) of cases, among them 22 were not previously described". Among the newly identified variants in the NR1A1 gene, two lead to the premature stop codon -p. Y197X and p. Y25X, two lead to a shift in the reading frame-p. N385fs and p. L245fs, which does not allow us to doubt their pathogenicityAmong the previously undescribed variant changes, 5 missense mutations (p. C283Y, p. C283B, p.H24Q, p.M126K, p.E81K) and 1  synonymous substitution affecting the splicing site (E330E) were evaluated as pathogenic, and 5 others as probably pathogenic.Has been corrected to read: Among the newly identified variants in the NR1A1 gene, two lead to the premature stop codon -p.
