Phenotype and genotype correlation of the microconversion from the CYP21A1P to the CYP21A2 gene in congenital adrenal hyperplasia

Deficiency of 21-hydroxylase is the most common form of congenital adrenal hyperplasia (CAH-21OH). We determined by allele-specific PCR the frequency of microconversion in the CYP21A2 gene in 50 Brazilian patients with the classical (salt wasting: SW and simple virilizing: SV) forms and nonclassical (NC) form of CAH-21OH and correlated genotype with phenotype. Genotypes were classified into three mutation groups (A, B, and C) based on the amount of enzymatic activity in in vitro studies using adrenal cells. In 94 unrelated alleles, we diagnosed 76% of the affected alleles after screening for 7 microconversions. The most frequent point mutations observed in this series were I172N (19%), V281L (18%), and IVS2,A/C>G,-12 (15%). In the SW form, the most frequent mutation was IVS2,A/C>G,-12 (38%), in the SV form it was I172N (53%), and in the NC form it was V281L (57.7%). We observed a good correlation between genotype and phenotype. Discordance between genotype and phenotype was found in one SV patient with a mild mutation in one of the alleles (R356W/V281L). However, we cannot rule out the presence of an additional mutation in these alleles. We also observed a good correlation of genotype with 17alpha-hydroxyprogesterone, testosterone, and androstenedione levels. The severity of external genitalia virilization correlated with the severity of mutation. In conclusion, the frequencies described in the present study did not differ from worldwide studies, including the Brazilian population. The few differences observed may reflect individual sample variations. This new Brazilian cohort study suggests the presence of new mutations in Brazilian patients with different forms of CAH-21OH.1311131

An Illustrative Case Of Léri-weill Dyschondrosteosis

We report on a girl presenting Léri-Weill dyschondrosteosis (LWD) due to deletion of the SHOX gene. Her family included individuals with short stature alone or with both short stature and mesomelia or Madelung's deformity. The deletion was demonstrated through detection of hemizygosity for microsatellite markdrs SHOX-CA repeat, DXYS10092, DXYS10093 and DXYS10091 localized around the SHOX gene, with retention of paternal alleles in the proband and three of her sisters who had short stature as the only clinical feature. Hemizygosity for these loci was also observed in their mother, who had short stature too. The deletion in the proband was however larger, including locus DXY 10083. The proband's only sister with normal height did not carry the deletion. Family history suggests transmission of the deletion from the proband's maternal great-grandfather to her grandfather via the Y chromosome, and from the grandfather to the proband's mother via the X chromosome after crossing-over in the pseudoautosomal region proximal to the SHOX gene.

Mutations in SRY and WT1 genes required for gonadal development are not responsible for XY partial gonadal dysgenesis

The WT1 transcription factor regulates SRY expression during the initial steps of the sex determination process in humans, activating a gene cascade leading to testis differentiation. In addition to causing Wilms' tumor, mutations in WT1 are often responsible for urogenital defects in men, while SRY mutations are mainly related to 46,XY pure gonadal dysgenesis. In order to evaluate their role in abnormal testicular organogenesis, we screened for SRY and WT1 gene mutations in 10 children with XY partial gonadal dysgenesis, 2 of whom with a history of Wilms' tumor. The open reading frame and 360 bp of the 5' flanking sequence of the SRY gene, and the ten exons and intron boundaries of the WT1 gene were amplified by PCR of genomic DNA. Single-strand conformation polymorphism was initially used for WT1 mutation screening. Since shifts in fragment migration were only observed for intron/exon 4, the ten WT1 exons from all patients were sequenced manually. No mutations were detected in the SRY 5' untranslated region or within SRY open-reading frame sequences. WT1 sequencing revealed one missense mutation (D396N) in the ninth exon of a patient who also had Wilms' tumor. In addition, two silent point mutations were found in the first exon including one described here for the first time. Some non-coding sequence variations were detected, representing one new (IVS4+85A>G) and two already described (-7ATG T>G, IVS9-49 T>C) single nucleotide polymorphisms. Therefore, mutations in two major genes required for gonadal development, SRY and WT1, are not responsible for XY partial gonadal dysgenesis.172

Morphometry And Histology Of Gonads From 13 Children With Dysgenetic Male Pseudohermaphroditism

Background. - Dysgenetic male pseudohermaphroditism (DMP) is a sexual differentiation disorder characterized by bilateral dysgenetic testes, persistent müllerian structures, and cryptorchidism in individuals with a 46,XY karyotype. However, the histologic criteria for the diagnosis of DMP are poorly established. Objective. - To determine gonadal histology in children with DMP. Patients and Methods. - Between 1996 and 1998, 13 patients with DMP were evaluated on our service. The clinical diagnosis of DMP was based on a 46,XY karyotype, sex ambiguity, high levels of follicle-stimulating hormone and low levels Of antimüllerian hormone, a decreased testosterone response to human chorionic gonadotropin stimulation without accumulation of testosterone precursors, and the presence of müllerian structures. Molecular sequencing the HMGbox region of the SRY gene did not reveal any mutations. Biopsies were performed for 22 of 26 gonads (patient age at the time of biopsy, 16 months to 10 years). Conventional microscopy was used to evaluate mean tubular diameter, tubular fertility index, and number of Sertoli cells per tubular profile. Results. - All 26 gonads were located outside of the labioscrotal folds. Their histologic features varied from only a reduction in tubular size to features of a streak gonad. Five of the 22 gonads grossly resembled a streak gonad. The mean tubular diameter was severely reduced (>30% reduction relative to the normal tubular diameter for the patient's age) in 4 gonads, markedly reduced (10%-30%) in 11 gonads, slightly reduced (<10%) in one gonad, and normal in one gonad. The tubular fertililty index, expressed as the percentage of tubular profiles containing germ cells, was severely reduced (<30% of normal values) in 9 gonads, markedly reduced (50%-30%) in 2 gonads, and normal in 6 gonads. The number of Sertoli cells per tubular profile was elevated in 16 gonads and normal in one gonad. Thin tubules surrounded by fibrous tissue were occasionally observed. Conclusion. - The histologic findings confirmed the clinical diagnosis of DMP in every patient in the present series. However, gonadal histology was variable, and careful morphometric evaluation may be necessary to establish the diagnosis.1255652656Robboy, S.J., Miller, T., Donahoe, P.K., Dysgenesis of testicular and streak gonads in the syndrome of mixed gonadal dysgenesis: Perspective derived from clinicopathologic analysis of twenty-one cases (1982) Hum Pathol, 13, pp. 700-716Troche, V., Hernandez, E., Neoplasia arising in dysgenetic gonads (1986) Obstet Gynecol Surv, 41, pp. 74-79Krasna, I.H., Lee, M.L., Smilow, P., Sciorra, L., Eierman, L., Risk of malignancy in bilateral streak gonads: The role of the Y chromosome (1992) J Pediatr Surg, 27, pp. 1376-1380Rohatgi, M., Gupta, D.K., Menon, P.S., Verma, I.C., Mathur, M., Mixed gonadal dysgenesis and dysgenetic male pseudohermaphroditism - A critical analysis (1992) Indian J Pediatr, 59, pp. 487-500Rey, R.A., Belville, C., Nhou-Fékété, C., Evaluation of gonadal function in 107 intersex patients by means of serum antimüllerian hormone measurement (1999) J Clin Endocrinol Metab, 84, pp. 627-631Stuchi-Perez, E.G., Lukas-Croisier, C., Castro, M., Evaluation of the tubular and interstitial functions of the testis in 46,XY patients with ambiguous genitalia (2000) J Pediatr Endocrinol Metab, 13, pp. 605-612Chang, H.J., Clark, R.D., Bachman, H., The phenotype of 45,X/46,XY mosaicism: An analysis of 92 prenatally diagnosed cases (1990) Am J Hum Genet, 46, pp. 156-167Rajfer, J., Walsh, P.C., Mixed gonadal dysgenesis: Dysgenetic male pseudoher-maphroditism (1981) The Intersex Child: Pediatric and Adolescent Endocrinology, pp. 103-115. , Josso N, ed.

The fraction of cancer attributable to ways of life, infections, occupation, and environmental agents in Brazil in 2020

Many human cancers develop as a result of exposure to risk factors related to the environment and ways of life. The aim of this study was to estimate attributable fractions of 25 types of cancers resulting from exposure to modifiable risk factors in Brazil. The prevalence of exposure to selected risk factors among adults was obtained from population-based surveys conducted from 2000 to 2008. Risk estimates were based on data drawn from metaanalyses or large, high quality studies. Population-attributable fractions (PAF) for a combination of risk factors, as well as the number of preventable deaths and cancer cases, were calculated for 2020. The known preventable risk factors studied will account for 34% of cancer cases among men and 35% among women in 2020, and for 46% and 39% deaths, respectively. The highest attributable fractions were estimated for tobacco smoking, infections, low consumption of fruits and vegetables, excess weight, reproductive factors, and physical inactivity. This is the first study to systematically estimate the fraction of cancer attributable to potentially modifiable risk factors in Brazil. Strategies for primary prevention of tobacco smoking and control of infection and the promotion of a healthy diet and physical activity should be the main priorities in policies for cancer prevention in the country. \ua9 2016 Azevedo e Silva et al.

COVID-19 no estado de São Paulo: a evolução de uma pandemia

OBJECTIVES: To describe retrospectively severe hospitalized cases and deaths related to the COVID-19 epidemic in the state of São Paulo, starting from the date of the first record with symptoms onset on 02/10/2020 up to 05/20/2021 records. METHODS: This is a descriptive study. The data source used was from the Influenza Epidemiological Surveillance System (SIVEP-Gripe). The rates of incidence, mortality and accumulated incidence in the period were calculated, stratified by age group and Regional Health Department (DRS). In addition, severe cases were geocoded to analyze their spread across the state; and the Effective R, which determines the spread potential of a virus within a population, was calculated. RESULTS: There was a significant increase in severe cases and deaths recorded in the period of one year, with incidence and mortality rates being heterogeneous within the state. The most critical periods regarding the incidence of severe cases occurred between May and July 2020 and between March and April 2021. The DRSs in São José do Rio Preto, Grande São Paulo and Araçatuba concentrated the highest incidence and mortality rates. Severe cases and deaths were more frequent in men and in the population over 60 years, while the main risk conditions related to deaths were heart disease (59%) and diabetes (42,8%). CONCLUSIONS: These results not only provide a detailed profile for more efficient control action plan, but will also allow the historical understanding of the COVID-19 evolution within the state of São Paulo.OBJETIVOS: Descrever, de forma retrospectiva, os casos graves hospitalizados e óbitos relacionados à epidemia de COVID-19 no estado de São Paulo, desde a data do primeiro registro com início de sintomas em 10/02/2020 até registros disponíveis em 20/05/2021. MÉTODOS: Trata-se de um estudo descritivo realizado por meio da base de dados do Sistema de Vigilância Epidemiológica da Gripe (SIVEP-Gripe). Foram calculadas as taxas de incidência, mortalidade e incidência acumulada no período, estratificadas por faixa etária e Departamento Regional de Saúde (DRS). Os casos graves foram geocodificados para análise de seu espalhamento pelo estado e foi calculado o R Efetivo, que estima o potencial de propagação de um vírus dentro de uma população. RESULTADOS: Houve um aumento significativo dos casos graves e óbitos registrados no período de um ano, sendo que as taxas de incidência e mortalidade foram heterogêneas dentro do estado. Os períodos mais críticos em relação à incidência de casos graves ocorreram entre maio e julho de 2020 e entre março e abril de 2021. Os DRS de São José do Rio Preto, Grande São Paulo e Araçatuba concentraram as maiores taxas de incidência e mortalidade. Os casos graves e óbitos foram mais frequentes nos homens e na população acima de 60 anos, e as principais condições de risco relacionadas aos óbitos foram cardiopatia (59%) e diabetes (42,8%). CONCLUSÕES: Espera-se que esses resultados ofereçam embasamento e possam contribuir para uma ação de controle mais eficiente, além de permitir o entendimento histórico da evolução da COVID-19 no estado

Clinical And Molecular Spectrum Of Patients With 17β-hydroxysteroid Dehydrogenase Type 3 (17-β-hsd3) Deficiency [espectro Clínico E Molecular De Pacientes Com Deficiência De 17β-hidroxiesteroide Desidrogenase Tipo 2 (17-β-hsd3)]

The enzyme 17β-hydroxysteroid dehydrogenase type 3 (17-β-HSD3) catalyzes the conversion of androstenedione to testosterone in the testes, and its deficiency is a rare disorder of sex development in 46,XY individuals. It can lead to a wide range of phenotypic features, with variable hormonal profiles. We report four patients with the 46,XY karyotype and 17-β-HSD3 deficiency, showing different degrees of genital ambiguity, increased androstenedione and decreased testosterone levels, and testosterone to androstenedione ratio G novel mutation, and c.277+4A>T mutation, both located within the intron 3 splice donor site of the HSD17B3 gene, were identified in case 3. In addition, homozygosis for the missense p.Ala203Val, p.Gly289Ser, p.Arg80Gln mutations were found upon HSD17B3 gene sequencing in cases 1, 2, and 4, respectively. © ABEM todos os direitos reservados.568533539Andersson, S., Moghrabi, N., Physiology and molecular genetics of 17beta-hydroxysteroid dehydrogenases (1997) Steroids, 62, pp. 143-147Lukacik, P., Kavanagh, K.L., Oppermann, U., Structure and function of human 17beta-hydroxysteroid dehydrogenases (2006) Mol Cell Endocrinol, 248, pp. 61-71Labrie, F., Luu-The, V., Lin, S.X., Labrie, C., Simard, J., Breton, R., The key role of 17 beta-hydroxysteroid dehydrogenases in sex steroid biology (1997) Steroids, 62, pp. 148-158George, M.M., New, M.I., Tem, S., Sultan, C., Bhangoo, A., The clinical and molecular heterogeneity of 17aHSD3 enzyme deficiency (2010) Horm Res Paediatr, 74, pp. 229-240Boehmer, A.L., Brinkmann, A.O., Sandkuijl, L.A., Halley, D.J., Niermeijer, M.F., Andersson, S., 17beta-hydroxysteroid dehydrogenase-3 deficiency: Diagnosis, phenotypic variability, population genetics, and worldwide distribution of ancient and de novo mutations (1999) J Clin Endocrinol Metab, 84, pp. 4713-4721Mendonça, B.B., Inacio, M., Arnhold, I.J., Costa, E.M., Bloise, W., Martin, R.M., Male pseudohermaphroditism due to 17beta-hydroxysteroid dehydrogenase 3 deficiency.

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio
