1. Long-term follow-up of a female with congenital adrenal hyperplasia due to P450-oxidoreductase deficiency
SUMMARY P450 oxidoreductase deficiency (PORD) is a variant of congenital adrenal hyperplasia that is caused by POR gene mutations. The POR gene encodes a flavor protein that transfers electrons from nicotinamide adenine dinucleotide phosphate (NADPH) to all microsomal cytochrome P450 type II (including 21-hydroxylase, 17α-hydroxylase 17,20 lyase and aromata

2. Clinical and molecular analysis of patients with disorders of gonadal development / Análise clínica e molecular de pacientes com distúrbios do desenvolvimento gonadal
Introdução: O termo distúrbios do desenvolvimento gonadal (DDG) inclui condições congênitas nas quais o desenvolvimento gonadal é atípico. Estudos feitos em camundongos observaram que alguns genes como o Cbx2 e o Tcf21 interferem na fase inicial do desenvolvimento gonadal, afetando tanto gônadas XX quanto XY. O gene Dhh, por sua vez, codifica o fato

3. Análise citogenética dos pacientes com suspeita de Síndrome de UIIrich-Turner no estado do Ceará Brasil. / Cytogenetic analysis of patients with suspected UIIrich-Turner syndrome in the state of Ceará - Brazil.
A Síndrome de Ullrich Turner (SUT) é o mais comum distúrbio cromossômico que causa baixa estatura em mulheres. Em 50% dos casos, um cromossomo do par sexual inteiro (cariótipo 45,X) é perdido. Os outros 50% das mulheres possuem um nível de anormalidades cariotípicas incluindo a ausência parcial do segundo cromossomo X e mosaicismos. Não há relaç�

4. An XX female with sexual infantilism, absent gonads, and lack of Müllerian ducts.
A patient with a 46,XX chromosome constitution showed the following main characteristics: lack of secondary sexual development, female external genitalia with absence of vagina, no gonadal structures, and complete lack of internal genitalia. This is a variant of the gonadal agenesis syndrome so far only described in association with and XY chromosome compone

5. Gonadal dysgenesis in a 46,XY female mosaic for double autosomal trisomies 8 and 21.
The proband was evaluated at 19 years of age because of primary amenorrhoea and, on chromosomal analysis, was found to have a 46,XY karyotype in 75% of her cells and 48,XY, +8, +21 in 25% of her cells. She appeared normal at birth and exhibited normal intellectual and physical development until puberty when secondary sexual differentiation failed. This young

6. Molecular basis of aromatase deficiency in an adult female with sexual infantilism and polycystic ovaries.
We identified two mutations in the CYP19 gene responsible for aromatase deficiency in an 18-year-old 46,XX female with ambiguous external genitalia at birth, primary amenorrhea and sexual infantilism, and polycystic ovaries. The coding exons, namely exons II-X, of the CYP19 gene were amplified by PCR from genomic DNA and sequenced directly. Direct sequencing

7. Gsh-1, an orphan Hox gene, is required for normal pituitary development.
The anterior pituitary regulates the function of multiple organ systems as well as body growth, and in turn is controlled by peptides released by the hypothalamus. We find that mutation of the Gsh-1 homeobox gene results in pleiotropic effects on pituitary development and function. Homozygous mutants exhibit extreme dwarfism, sexual infantilism and significa
